Sloshing of LNG cargo can cause high impact loads on the supporting and containing structures. This is particularly critical for membrane-type tanks since these will have flat surfaces and corner regions which can lead to increased peak pressures for sloshing impacts. The membrane-type containment system is much more flexible compared to the steel hull structure. As a result, fluid-structure interaction plays an important role in the structural analysis of the containment system under sloshing load. This study is based on the direct calculation method of applying sloshing loads to the KC-1 basic insulation system using finite element analysis. The structural analysis of KC-1 basic insulation system considers the dashpot as fluid-structure interaction between liquid cargo and the LNG containment system. The maximum stress of the polyurethane form for KC-1 insulation system is 1.5 times lower than one without dashpot.

Fatigue crack was detected from a temperature change around surface crack using the thermographic technique. Thermal gradient across the crack decreased very much due to thermal resistance of contact surface in the crack. Heat diffusion flow passing through the discontinuity was visualized in temperature by infrared camera to find and locate the crack. A fatigue crack specimen(SM-45C), which was prepared according to KS specification and notched in its center to initiate fatigue crack from the notch tip, was heated by halogen lamp at the end of one side to generate a heat diffusion flow in lateral direction. A abrupt jump in temperature across the fatigue crack was observed in thermographic image, by which the crack could be located and sized from temperature distribution.

On January 27, 2005, the central government of the Republic of Korea designated Jeju Island as an Island of World Peace based on Article 12 of the Special Act for the Jeju Free International City, and the WHO designated Safe Community Jeju in July, 2007. Whenever an industrial accident occurs on Jeju Island, reports in the media raise the question of whether Jeju is a safe city or not. But due to the characteristics of construction sites in Jeju, it is very difficult to employ workers of a certain level. For the safety of workers, it is also thought that owners should make a decisive investment to introduce an education and reward system in order to improve the consciousness level of workers. This research focuses on first-aid on construction sites. It then surveys the level of construction safety management, and suggests improvements in construction safety control and first-aid.

A gas chromatography-mass spectrometric (GC-MS) method was developed for determining 25 semivolatile organic compounds in water. A 1.0 L water sample was placed in a separatory funnel and saturated with NaCl, and the solution was extracted two times with 40 mL of methylene chloride. Under the established condition, the linear quantification range was 0.02-800 ng/L and the relative standard deviation was less than 15%. The method was used to analyze 16 surface water samples collected from various regions in Gum-River. The samples revealed SVOC concentrations in the range of 0.02-96.8 ng/L. Maximum concentrations of VOCs detected were not exceeded the EPA or Germany guidelines in any of the samples. The developed method may be valuable for monitoring SVOCs in water.

This is the comparative study about analyzing the methodologies of building ontology with IEEE Standard 1074-1997. The methodologies are chosen to be analyzed. They are OTK, CommanKADS, ONIONS and Noy & McGuinness's Ontology Development 101. On the basis of analyzing, the ontology development process is proposed after the strong points of four methodologies are accepted but the weak points of them are supplemented. The sixth development steps are following: 1) Conducting the feasibility study about ontology building as the pre-development process 2) Setting up the purpose of the ontology development as the starting point of the building 3) Considering the integration of the existing ontologies for the knowledge reuse 4) Constructing the ontology by defining the concepts and relations 5) Evaluating and testing the ontology for the completeness 6) Containing the ontology maintenance for the sustainable use.

The development of science and technology to accompany the convenience of civilization but in addition to nuclear, gas, explosion, accident and spill all over the world with the possibility of a chemical or biological terrorism response efforts collectively as a response to the urgent task of a nation. In this study major economies such as the U.S. and Canada analyzed to investigate the CBRN training programs to fit the reality in Korea CBRN training programs were developed. also the development of training programs to CBRN Korean Activity-Action Diagram technique utilized by CBRN scenarios corresponding to each event needs to be taken when the Activity is defined by its detailed definition of corrective actions for the CBRN Activity to define context-sensitive actions in particular to enable the functionality of the structure in case of CBRN emergency initial response was to establish education and training programs.

This research has investigated the cyber university students' awareness of the portal service of the digital library. In order to identify characteristics of the cyber university students, the research examined demographic characteristics of the students and library usage status. Awareness on the portal service was also analyzed in accordance with the characteristics of the users. The analysis showed that the most needed service was concise/full search service, which was the most frequently used service. The students were most satisfied with the liaison service; service awareness of several libraries showed statistically significant results depending on age, occupation. Based on the analysis, the research proposed the following measures to increase the use of the digital library of cyber university students: active PR on library service, and intensifying the library user education.

For the development of a curriculum of the serious game for the elderly in preparation of senior society, we have surveyed students of both college of humanity and college of engineering for their perception of importance and necessity on the subjects prepared by this team. We analyzed their common points and different points, and developed a new interdeciplinary curriculum for students in both college. The curriculum has been opened in the last semester successfully.

The purpose of this study was to identify converged factors influencing subjective health status of patients with depression. The subjects of this study are 117 people answered that depression years of the 2013 National Health and Nutrition Examination Survey subjects. The results of this study were that the factors influencing subjective health status were education level, number of family member, quality of life, subjective body awareness, stress and they explained 55.9% of the variance. Therefore the intervention is considering various converged influencing factors should be done when the primary care for the promotion of subjective health status of patients with depression. This study identified a complex convergence of factors influence the subjective health status of patients with depression could be helpful on developing nursing intervention programs. It is necessary to identify forward more various social religious factors and disease influence the subjective health status of patients with depression.

This study attempts to suggest a theoretical basic frame that is needed for nursing intervention regarding the sexual experiences of the mentally disabled. The data were collected through a series of interviews with 14 participants. With permission of the mentally disabled, the interviews were recorded and transcribed. The data were analyzed using the framework of grounded theory mapped out by Strauss & Corbin(1998). The following 3 theories were confirmed on the basis of repetitive relations: becoming nest type, exercising self-restraint type, getting tangled type. Therefore, it is necessary to develop a realistic sex education that is relevant to hospital, community mental health center, and culture. The nurse is required to activily participate in educating the mentally disabled with a diverse approach to instill and nurture the sober perspective about sex such as the pleasure, life, intimacy based on sexual equality.
