This study proposes an execution protocol for fashion therapy. Research on fashion therapy are limited and insufficient for the current need for the establishment of a fashion therapy theory. This study introduces cognitive behavior therapy, embodied cognition, and object relations theory as theories that underlie fashion therapy. A fashion therapy system model is provided based on the analysis of art therapy to explore its applicability to fashion therapy. The fashion therapy system model utilizes fashion items to managing pain and stress to better competence, encouragement and self-expression mechanisms to improve social, psychological, emotional and behavioral functions. In addition, 8 phases of the fashion therapy process (inquiry, forming rapport, assessment, goal-objective, observation, selection of strategy and design, practice, and the final evaluation and closing of fashion therapy) are suggested for developing a practical fashion therapy program. This study is to help overcome a negative perspective on fashion that provokes an excessive spending behavior and to make a practical contribution by creating more social value through fashion. The significance of the study is in the attempt to create an interdisciplinary approach of psychotherapy and fashion that can be extend into the fashion and textile discipline.

A high quality, long-term, high-resolution precipitation dataset is an essential in climate analyses and global water cycles. Rainfall data from station observations are inadequate over many parts of the world, especially North Korea, due to non-existent observation networks, or limited reporting of gauge observations. As a result, satellite-based rainfall estimates have been used as an alternative as a supplement to station observations. The Climate Hazards Group Infrared Precipitation (CHIRP) and CHIRP combined with station observations (CHIRPS) are recently produced satellite-based rainfall products with relatively high spatial and temporal resolutions and global coverage. CHIRPS is a global precipitation product and is made available at daily to seasonal time scales with a spatial resolution of 0.05° and a 1981 to near real-time period of record. In this study, we analyze the applicability of CHIRPS data on the Korean Peninsula by supplementing the lack of precipitation data of North Korea. We compared the daily precipitation estimates from CHIRPS with 81 rain gauges across Korea using several statistical metrics in the long-term period of 1981-2017. To summarize the results, the CHIRPS product for the Korean Peninsula was shown an acceptable performance when it is used for hydrological applications based on monthly rainfall amounts. Overall, this study concludes that CHIRPS can be a valuable complement to gauge precipitation data for estimating precipitation and climate, hydrological application, for example, drought monitoring in this region.

본 논문에서는 전파강수계의 운영제어 및 자료처리를 위한 통신 및 자료처리 전략을 개발하였다. 전파강수계는 24GHz 대역의 이중편파 관측을 통하여 반경 1km 이내의 강수장을 산출하고 최종적으로 관측지역내의 면적강수를 산출하고자 하는 소형 시스템이다. 소형 시스템의 특성상 시스템 내의 제한된 자원을 활용하되 정확한 강수측정을 위한 방안이 고려되어야 하고 무인운영 및 원격 관리를 목적으로 하기 때문에 네트워크의 사용도 최소화해야 할 필요가 발생한다. 이러한 제한 사항의 극복을 위하여 자료의 품질관리 측면에서는 비기상 에코의 제거를 위해서 퍼지 논리(Fuzzy logic)을 이용한 품질관리 기법을 적용하였고, 강수강도 산출을 위해서 다양한 강수강도 추정식을 활용한 강수장 가중합성 전략을 개발하였다. 또한 가변 통신데이터를 이용하여 전파강수계와 원격지 관리 컴퓨터간의 통신량을 최소화하는 전략을 개발하였다. 이러한 소프트웨어 자료처리 전략개발을 통해 원격지에 설치되어 운영될 전파강수계를 안정적으로 운영할 수 있는 통신 및 자료처리 시스템을 개발할 수 있을 것으로 기대한다.

Purpose: This micro-ethnographic study aimed to understand coping experiences of Korean-American (K-A) women after diagnosis with breast cancer due to a hereditary gene mutation. Methods: Participatory observation and in-depth interviews were performed at one breast cancer screening center in Southern California, in 2005 with eleven first generation K-A immigrant women. All transcribed interviews and field notes were analyzed using ethnographic methodology. Results: K-A women's experience varied based on acculturation risk factors including: limited English speaking ability; disrupted family relationships, individualistic family values, or intergenerational communication barriers; lack of Korean speaking nurses; and Korean physicians' who lacked knowledge about hereditary breast cancer risk. These risk factors led to isolation, loneliness, lack of emotional and social support. In comparison to Korean homeland women in a similar medical situation, these K-A immigrants felt disconnected from the healthcare system, family support and social resources which increased their struggling and impeded coping during their survivorship journey. These women were not able to access self-support groups, nor the valuable resources of nurse navigator programs. Conclusion: Professional oncology associations for nurses and physicians have a moral obligation to support and promote knowledge of hereditary cancer risk and self-help groups for non-native speaking immigrants.

하이브리드 로켓 연소에서 발생하는 산화제 난류 유동과 연료의 기화로 인한 분출유동 사이의 상호 간섭은 매우 복잡하고 특별한 유동 간섭을 일으킨다. 이를 연구하기 위하여 연소반응을 제외하고, 산화제의 난류 유동과 연료 벽면에서의 분출 유동을 모사한 채널 유동에 대한 LES 해석을 수행하였다. 고체추진 로켓의 연소 과정에서 관찰되는 현상과 매우 흡사하게 벽면 근처에서 특정주파수로 진동하는 유동 현상이 존재한다는 것을 확인하였고, 산화제와 분출 유동의 간섭에 기인한 유동의 진동현상은 벽면 근처의 매우 얇은 영역에서만 존재하였다. 큰 길이 스케일의 유동현상을 보여주는 압력 섭동장으로부터 채널 내 주유동이 특정 주파수 특성을 갖고 하류로 진행해 가는데, 이는 산화제 유동이 분출유동과 상호작용을 하면서 발생된 전단유동의 특성을 나타낸 것이다. 그러나 하이브리드 로켓 연소실 유동의 진동 특성은 고체 추진 로켓에서 관찰되는 유동 특성과는 달리, 진동의 강도가 벽면에서 온도 구배를 변화시켜 열전달의 향상을 발생시키기에는 충분하지 못한 것으로 보인다. 그러나 벽면 근처에서 특정 주파수 특성을 갖는 유동현상이 존재한다는 사실은 비슷한 크기의 주파수를 갖는 음향 가진과 같은 외부교란이 작용한다면 공진으로 발전할 수 있는 가능성을 의미한다.

Seasonal fluctuations of physico-chemical and biological aspects of the environment were studied in Vladivostok harbour (Golden Horn Bay, the East Sea/Sea of Japan). The benthic community structure was described with a focus on size-spectra (bacteria, meio- and macrofauna) related with the chemical environment and chemical fluxes in sediment and to reveal their possible ecological role in the process of bioremediation of the environment. Samples from two sites with different concentrations of heavy metals (Fe, Zn, Cu, Pb, Mn, Cr, Ni Cd, Co) and petroleum hydrocarbon were assessed by a number of methods. These included plate counts of culturable bacteria, observation through a scanning electron (SEM) and transmission electron microscope (TEM). These approaches were complemented with microscopic assessments of the diversity of the benthic community. The specific communities had a limited number of species, tolerant to abnormally high levels of toxic compounds. The dominant species were presented by several sho.1-lived small polychaetes (Capitella capitata) and nematodes (Oncholaimium ramosum). The highest population density was recorded in microbenthos, in various diatoms, various physiological groups of bacteria which participate in biomineralization: marine heterotrophic bacteria, which oxidized oil, black oil in addition to groups resistant to heavy metals. They have the entire set of mechanisms for neutralizing the negative effect of those compounds, forming the detrital food web and biogeochemical circulation of material in sediments, which results in the biological self-recycling of sea basins. Macro- and meiobenthic organisms were more sensitive to a greater extent of $H_2S$ and petroleum hydrocarbons than to metal content, but the within-site rankings were the same as those achieved for microbiological analyses.

Objectives: The objective of this study is compare the rate of marginal bone resorption around hydroxyapatite-coated implants given different loading times in order to evaluate their stability. Materials and Methods: The study was conducted retrospectively for one year, targeting 41 patients whose treatment areas were the posterior maxilla and the mandible. Osstem TS III HA (Osstem Implant Co., Busan, Korea) and Zimmer TSV-HA (Zimmer Dental, Carlsbad, CA, USA), which employ the new hydroxyapatite coating technique, were used. The patients were divided into two groups - immediate and delayed loading - and the bone level at the time of loading commencement and after one year of loading was measured using periapical radiography. Differences between the groups were evaluated using Mann-Whitney (${\alpha}$=0.05). Results: For all patients as a single group, the survival rate of the implants was 100%, and the mean marginal bone loss was $0.26{\pm}0.59mm$. In comparison of the differences by loading, mean marginal bone loss of $0.32{\pm}0.69mm$ was recorded for the immediate loading group whereas the delayed loading group had mean marginal bone loss of $0.16{\pm}0.42mm$. However, the difference was not significant (P>0.05). Conclusion: Within the limited observation period of one year, predictable survival rates can be expected when using immediately loaded hydroxyapatite-coated implants.

다양한 암석에서 발달하는 풍화혈은 기반암의 암석학적 특징과 형성과정에 대해 활발하게 논의되고 있는 지형이다. 사천시 다평리 해안은 이암과 사암의 호층이 분포하는 곳으로 사암이 노출된 지역의 쇼어플랫폼과 해식애에서 다양한 풍화혈이 발달하였다. 절리의 발달, 광맥의 관입, 암석의 물리 화학적 특성에 따른 풍화혈의 발달 특성과 분포의 공간적 한계를 분석하기 위해 지형조사, XRD분석, 편광현미경 관찰을 수행하였다. 조사 및 분석결과 이곳은 타포니와 나마가 동일한 지역에 분포하는 지역적 특성을 보이며, 절리의 확대, 성장에 의해 기존 풍화혈이 파괴되고 새로운 타포니가 형성되고 있다. 석영맥으로 밝혀진 광맥은 절리와 결합하여 풍화혈의 발달을 가속화시키기도 하지만, 풍화혈의 성장방향에 수직으로 관입한 광맥은 성장을 방해하기도 한다. 일반적으로 풍화혈은 암석의 종류에 관계없이 발달하는 것으로 알려져 있으나, 암석학적 특성을 분석한 결과 이암과 같이 쪼개짐과 깨짐이 발달한 미립질의 암석에서는 풍화혈의 성장이 제한된다.

Due to the difficulties for measuring flood discharge in the dangerous field conditions, conventional instruments with relatively low accuracy such as float still have been widely utilized for the field survey. It is also limited to use simple stage-discharge relationship for assessment of the flood discharge, since the stage-discharge relationship during the flood becomes complicated loop shape. In recent years, various non-intrusive velocity measurement techniques such as electromagnetic wave or surface images have been developed, which is quite adequate for the flood discharge measurements. However, these new non-intrusive techniques have little tested in the flood condition, though they promised efficiency and accuracy. Throughout the field observations, we evaluated the validity of these techniques by comparing discharge and velocity measurements acquired concurrently during the flood in a mountain stream. As a result, the flood discharge measurements between electromagnetic wave and surface image processing techniques showed high positive relationship, but velocities did not matched very well particularly for the high current speed more 3 m/s. Therefore, it should be noted here that special cares are required when the velocity measurements by those two different techniques are used, for instance, for the validation of the numerical models. In addition, authors assured that, for the more accurate flood discharge measurements, velocity observation as well as stage height is strongly necessary owing that the unsteady flow occurs during the flood.
