Nanoencapsulated Phase-Change Materials: Versatile and Air-Tolerant Platforms for Triplet-Triplet Annihilation Upconversion.

Efficient and long-term stable triplet-triplet annihilation upconversion (TTA-UC) can be achieved by effectively protecting the excited organic triplet ensembles from photoinduced oxygen quenching, and discovery of a new material platform that promotes TTA-UC in ambient conditions is of paramount importance for practical applications. In this study, we present the first demonstration of an organic nonparaffin phase-change material (PCM) as an air-tolerant medium for TTA-UC with a unique solid-liquid phase transition in response to temperature variation. For the proposed concept, 2,4-hexadien-1-ol is used and extensively characterized with several key features, including good solvation capacity, mild melting point (30.

Upconverting Oil-Laden Hollow Mesoporous Silica Microcapsules for Anti-Stokes-Based Biophotonic Applications.

A recyclable, aqueous phase functioning and biocompatible photon upconverting system is developed. Hollow mesoporous silica microcapsules (HMSMs) with ordered radial mesochannels were employed, for the first time, as vehicles for the post-encapsulation of oil phase triplet-triplet annihilation upconversion (TTA-UC), with the capability of homogeneous suspension in water. In-depth characterization of such upconverting oil-laden HMSMs (UC-HMSMs) showed that the mesoporous silica shells reversibly stabilized the encapsulated UC oil in water to allow efficient upconverted emission, even under aerated conditions.

Decision Making Regarding Key Elements of Korean Disaster Psychiatric Assistance Teams Using the Analytic Hierarchy Process.

Objective: The purpose of this study was to determine the key components of Korean disaster psychiatric assistant teams (K-DPATs), to set up new mental health service providing system for the disaster victims.

Methods: We conducted an analytic hierarchy process (AHP) involving disaster mental health experts, using a pairwise comparison questionnaire to compare the relative importance of the key components of the Korean disaster mental health response system. In total, 41 experts completed the first online survey; of these, 36 completed the second survey.

Flexible and Micropatternable Triplet-Triplet Annihilation Upconversion Thin Films for Photonic Device Integration and Anticounterfeiting Applications.

Triplet-triplet annihilation upconversion (TTA-UC) has recently drawn widespread interest for its capacity to harvest low-energy photons and to broaden the absorption spectra of photonic devices, such as solar cells. Although conceptually promising, effective integration of TTA-UC materials into practical devices has been difficult due to the diffusive and anoxic conditions required in TTA-UC host media. Of the solid-state host materials investigated, rubbery polymers facilitate the highest TTA-UC efficiency.

System effectiveness of detection, brief intervention and refer to treatment for the people with post-traumatic emotional distress by MERS: a case report of community-based proactive intervention in South Korea.

Background: Korea has experienced diverse kind of disasters these days. Among them the 2015 middle eastern respiratory syndrome (MERS) outbreak imposed great psychological stress on almost all Korean citizens. Following the MERS outbreak, government is reviewing overall infectious disease management system and prioritizing the establishment of mental health service systems for infectious disease.

A Molecular Dynamics Study on Controlling the Self-Assembly of β-Sheet Peptides with Designer Nanorings.

Recently, a rational approach for constructing β-barrel protein mimics by the self-assembly of peptide-based building blocks has been demonstrated. We performed molecular dynamics simulations of nanoring formation by means of the self-assembly of designed β-sheet-forming peptides. Several factors contributing to the stability of the nanoring structures with respect to size were investigated.

How can a change in the operating system of the mental health review board promote the discharge of long-term hospitalized psychiatric patients? A case study of Seoul city.

Background: One of the most typical and chronic problem in Korean mental health system is the prolonged length of hospital stay. In contrast to there are many components which leads to long length of stay of psychiatric patients in Korean situation such as low and fixed medical fee for psychiatric inpatient treatment, shortage of community resources, lack of care-givers' awareness and so on, there are just few mechanisms to handle this issue such as Mental Health Review Board (MHRB) which is based on Mental Health Act since 1995. However, the discharge order rate was very low and there community care system after discharge order is still very weak.

Patterns of antipsychotic prescription to patients with schizophrenia in Korea: results from the health insurance review & assessment service-national patient sample.

This study aimed to analyze the patterns of antipsychotic prescription to patients with schizophrenia in Korea. Using the Health Insurance Review & Assessment Service-National Patients Sample (HIRA-NPS), which was a stratified sampling from the entire population under the Korean national health security system (2009), descriptive statistics for the patterns of the monopharmacy and polypharmacy, neuropsychiatric co-medications, and prescribed individual antipsychotic for patients with schizophrenia were performed. Comparisons of socioeconomic and clinical factors were performed among patients prescribed only with first- and second-generation antipsychotics.

Caregivers' acceptance of alternatives to long-term psychiatric hospitalization; lessons and debates from the South Korean situation.

Background: A political movement towards building alternatives to long-term hospitalization of psychiatric patients in Korea has gained momentum. We aimed to provide sturdy foundation needed to formulate the most rational policy by review of caregiver's opinion to the political alternatives under discussion for facilitating discharge of long-term stayed psychiatric patients in Korea.

Discussion: Caregivers in Korea, whose family members had been hospitalized longer than 6 months and all of whom applied to the Mental Health Review Board (MHRB) for an examination required for extended stay, have shown reluctance to take their patients back home.

The Association between Economic Status and Depressive Symptoms: An Individual and Community Level Approach.

Objective: The study was conducted to investigate the association between economic status and depressive symptoms by comparing the prevalence rates of depressive symptoms at community level and analyzing the possibility of depressive symptoms at individual level.

Methods: A survey was conducted from November, 2006 to November, 2007 on 966 and 992 representative subjects recruited by stratified clustered sampling in two regions located in Seoul. We used a standardized questionnaire including the Center for Epidemiologic Studies-Depression and questions on the socioeconomic characteristics.

Service priority and standard performance of community mental health centers in South Korea: a delphi approach.

Objective: The role of community mental health centers (CMHCs) in Korea is quite different than that of these centers in Western countries due to nation-specific health care system characteristics. For example, CMHCs of Korea are expected to provide services for serious mental illness in addition to other services in response to community needs, such as internet addiction of adolescents. Consequently, it is important to determine service priorities of CMHCs and to define standard service performances in order to maximize their effectiveness with limited resources.

[Medical care utilization status and associated factors with extended hospitalization of psychiatric patients in Korea].

Objectives: This study was performed to examine medical care utilization of psychiatric patients and to explore patients' characteristics associated with extended hospitalization.

Methods: Data were extracted from information of Korean Health Insurance Review and Assessment Service. All data associated with admission and outpatient clinic visit were analysed by patient characteristics.

The upward spiral of drug costs: a time series analysis of drugs used in the treatment of hemophilia.

Background: Hemophilia is an expensive disease because its treatment is heavily dependent on costly clotting factor drugs. Over the last nine years,a consortium of three Comprehensive Hemophilia Treatment Centers and other hospitals, which purchased clotting factors for their patients, has seen treatment costs escalate on average 17% annually. Currently, new, even more expensive drugs are entering the market.
