Objective-According to previous social survey, a high number of North Korean refugees (NKRs) in South Korea had suicidal ideation. The purpose of this study is to examine the related factors for suicidal ideation among NKRs by gender in South Korea. Methods-We examined the sample of NKRs, 701 subjects (men=160, women=-541) residing in South Korea, the participants were enrolled from October 2008 to May 2014. The related factors with suicidal ideation in NKRs were analyzed via a logistic regression analysis. Results-Refugee women were more likely to have suicidal ideation than men were. Although thoughts of suicide do not necessarily mean that they will follow through, however, there is an association that the higher rate of suicide also results in a higher rate of attempted suicide. In both genders, they tended to think more frequently about suicide who had stayed in South Korea for more than 5 years. In addition, higher frequencies of suicidal ideation also associated with higher level of perceived stress in both genders. Conclusion-The gender difference should be addressed when designing suicide prevention interventions among the North Korean population in South Korea.

The biosorption characteristics of SRCM 120569 biomass on anionic Congo red (CR) dye. SRCM 120569 strain isolated from Korean turbid rice wine (makgeolli) was identified by 16S rRNA sequence analysis as Bacillus licheniformis. Bacillus licheniformis SRCM 120569 (Genbank Accession No. MW819861) showed superior CR dye biosorption capacity in an aqueous solution. Maximum adsorption capacities of 61.2 and 133.1 mg/g were obtained at pH 3.41 and 0.01 g/50 mL dried cell dosage, respectively. The CR dye adsorption properties by the Bacillus licheniformis SRCM120569 strain were characterized by Fourier transform infrared spectroscopy (FT-IR), point of zero charge (pH<sub>pzc</sub>) analysis, and phylogenetic analysis. The biosorption isotherm and kinetic models are well described with the Langmuir adsorption isotherm and pseudo-second-order kinetic models.
A House Design Automation System Based on the "Design-by-Novice" Paradigm
Kim, Uk,Choi, Jinwon,Kim, SungAh Architectural Institute of Korea 1999 Architectural research Vol.1 No.1
This research investigates a system for house design automation. The system is based on an object-oriented building data model, aiming to support the house design process conducted by non-expert users. Its object model, with simple yet powerful user interfaces, enables a CAD system to handle a complicated building system with much ease. Hence, the model dramatically simplifies the design process beyond just the automatic document generation. In this paper, we discuss the aspects of the building data model, introduce critical concepts such as grid objects and structured floor plan, and present a prototype system called GPLAN. The system is implemented in the framework of our building data model, and it provides a host of intelligent features that have been proved useful for house design automation.

Lipids, which along with carbohydrates and proteins are among the most important nutrients for the living organism, have a variety of biological functions that can be applied widely in biomedicine. A fatty acid, the most fundamental biological lipid, may be classified by length of its aliphatic chain, and the short-, medium-, and long-chain fatty acids and each have distinct biological activities with therapeutic relevance. For example, short-chain fatty acids have immune regulatory activities and could be useful against autoimmune disease; medium-chain fatty acids generate ketogenic metabolites and may be used to control seizure; and some metabolites oxidized from long-chain fatty acids could be used to treat metabolic disorders. Glycerolipids play important roles in pathological environments, such as those of cancers or metabolic disorders, and thus are regarded as a potential therapeutic target. Phospholipids represent the main building unit of the plasma membrane of cells, and play key roles in cellular signaling. Due to their physical properties, glycerophospholipids are frequently used as pharmaceutical ingredients, in addition to being potential novel drug targets for treating disease. Sphingolipids, which comprise another component of the plasma membrane, have their own distinct biological functions and have been investigated in nanotechnological applications such as drug delivery systems. Saccharolipids, which are derived from bacteria, have endotoxin effects that stimulate the immune system. Chemically modified saccharolipids might be useful for cancer immunotherapy or as vaccine adjuvants. This review will address the important biological function of several key lipids and offer critical insights into their potential therapeutic applications.
Kim, Jinwon Smart Tourism Research Center 2021 Journal of smart tourism Vol.1 No.4
Although Geographic Information Systems (GISs) have commonly been employed as powerful tools for manipulating and displaying spatial data in community-based tourism, a variety of GIS functions still lack the capabilities required to assist multiple decision makers to come to consensual decisions. In this study, I propose an alternative approach: spatial multicriteria decision analysis (SMCDA) that could reflect diverse decision makers' preferences by integrating GISs and multicriteria decision analysis (MCDA). I review the small number of case studies that have employed SMCDA, with a focus on the roles of GISs and MCDA. The methodological integration of GISs and MCDA into multi-spatial decision support systems offers the potential to implement participatory decision-making to solve complex spatial problems in community-based tourism planning, development, and management.
Link Selection Algorithm of UWB Communications Considering Fading Statistics
Jinwon Choi,Yu-Suk Sung,Jeong-Wook Kim,Seong-Cheol Kim 대한전자공학회 2007 ITC-CSCC :International Technical Conference on Ci Vol.2007 No.7
This paper presents the link selection algorithm of Ultra Wide Band (UWB) communications considering fading statistics. In this algorithm, UWB devices decide the wireless link considering not only received signal strength but also fading statistics. Fading statistics follows the proposed channel model to the existence of line-of-sight (LOS).
