성장저해는 만성신부전 (chronic renal failure, CRF) 소아환자나 실험동물에게서 나타나는 합병증의 하나로, 그 발생기전이 잘 알려져 있지 않다. 성장저해를 일으키는 원인으로 비내분비적 요인 (metabolic acidosis, renal osteodystrophy, anemia)과 내분비적 요인의 복합적 결과로 생각하나, 비내분비적 요인들은 약물투여로 그 증세를 완화시켜도 성장저해에 대한 궁극적 치료효과는 나타나지 않는다. 따라서 성장 호르몬 (Growth Hormone, GH)이 관여하는 내분비적 요인의 변화에 그 병리기전이 있을 것으로 연구되어 왔다. GH는 직접적 성장 효과와 Insulin-like growth factor-1(IGF-I)을 간으로부터 유리시켜 나타나는 간접적 성장효과를 가지고 있다. 그런데 CRF환자의 GH 및 IGF-I 의 혈중 농도는 정상이거나, 흑은 오히려 증가상태에 있음에도 볼구하고 성장저해가 일어나는 것으로 보아, 환자의 말단기관 (end-organ)에 원인을 알 수 없는 저항성 (resistance)이 있다고 규정되어진다.

Since the late 1990s, mixed-use apartment, armed with high qualities and large scales with a high ratio of TFA(Total Floor Area) have been continuously provided accommodating exclusive community facilities along with high-tech securities, not to mention excellent skyline view. However, especially in mid-small cities, there have been only a few supplies. As a result, none of the mixed-use housing provided by high-end brands has ever been built in non-metropolitan area. But constructors couldn't plan the projects which aims to build the mixed-use apartment in local city, because they couldn't get the basic data or advanced research for feasibility analysis. Therefore, to suggest the useful price for mixed-use apartment supply project of local city, the PSM(Price Sensitivity Method) widely used for determining the price preferences as a market research tools has been applied. As analysis results, the estimated price of mixed-use apartment is 10.8% higher than general apartment, and mixed-use apartment has lower price sensitivity than general apartment. As price determinants, the age, education level and family size influence on UTP in significant level. It is expected that these research findings can be applied for establishing the solid marketing strategy of mixed-use apartment development project in local city.

The lifestyle of the new consumer class of people with diversified social structures and tastes is affecting society as a whole. As of now, emerging lots of complex cultural space with unique sensibility and individuality, this paper is about proposing the branding of a complex cultural space. I selected Sounds Hannam as a cultural complex and conducted in-depth interviews about brand experience and Ethnography. The study found that Sounds Hannam needs sense of hearing and smell because the sensory factors of the Sounds Hannam are concentrated in the visual field, and also, there is a need to create an appropriate communication channel through SNS. The Sounds Hannam had the characteristic factors of sensibility, relaxation and content based on a diversity different from the existing one. Throughout research, it was derived that planning space as a place to inspire people through spatial composition that triggers behavior and creative thinking is the goal of a complex cultural space and at the same time, an effective way to reflect the lifestyle of those in 20s.

In general, slope failures are occurred by the interaction among various factors(slope shape, hydraulic condition, and geologic condition, etc.). Hydraulic condition was a very important factor of a stability in cut slope and a dangerous of road passing. In this study, two cut-slope case on prescription of spring out water present. And this study data is used at practical affairs.

본 연구는 고객 지향적 통시서비스 품질기준 정립을 위한 기초연구 과제로서 크게 통신 고객의 감 성파악 및 감성실험 부분으로 이루어졌다. 우선, 전형적 감성공학적 접근법에 의해 화상회의 시스템 을 사용할 때 느낄 수 있는 206개의 감성어휘가 추출되었으며 이를 어의적 기준과 상대적인 중요도를 기준으로 하여 10개의 주요 감성으로 정리하였다. 사용자의 불만사항 등으로부터 감성실험을 위한 설계변수를 추출하였으며 실험환경 구축을 위한 simulator가 구성되었다. 실험은 음성지연, 음성에코, 화면의 초당 프레임수 그리고 통화주제를 인자로 하는 2$^{4}$요인배치법에 의해 실시되었으며 16명의 피실험자와 Magnitude Estimation방법을 이용하여 파악된 각 감성이 주관적으로 평가되었다. 분산분석 결과, 음성지연은 모든 주요 감성들에 유의한 영향을 미쳤으며, 화상프레임 수는 거리감과 안정성을 제외한 모든 사용자 감성에 주인자로 작용하였다. 또한 요인분석을 실시한 결과 동적인 요인과 정적인 요인으로 전체 감성을 구분지을 수 있었으며 속도감과 깨끗함이 각각을 대표하는 감성으로 나타났다. 주관적이고 복합적인 통신 사용자의 여러 감성을 단일 품질 평가지수로 나타내어 통신소비자의 시스템 선호도 평가에 사용할 수 있는 방법이 제안되었다.

At a time when trend called complex cultural space has recently been taking place in public libraries, this study analyzed the importance-performance of users regarding the use factors of public library's complex cultural space. Based on the results of the analysis, this study attempted to broaden the understanding of the library users' use of this space, and to suggest directions on which factors should be improved. The results of the study were as follows: First, only 5 of 41 factors for library complex cultural space have higher satisfaction than importance, so it is necessary to promote balanced development with focus on priority improvements rather than a specific sector. Second, it is necessary to provide various programs and services in consideration of visit characteristics, such as the users of the library complex cultural space are mainly used by themselves (42%) or with their families (18.2%), also more people (50.5%) use weekday afternoons than 35%, including weekend mornings and afternoons. Third, among the five use factors related to space, the remaining items except for 'Compatibility of Computer / Equipment Use' are located in the first quadrant where both importance and satisfaction are high or in the fourth quadrant which shows higher satisfaction than importance. This is a result that shows that the library is fully performing the diversification and complexion of the space basically aimed as a complex cultural space. Fourth, it is necessary to improve the public library's complex cultural space in the future based on the analysis results of the result of analysis of the importance-satisfaction the use of factors using the IPA analysis.

This study investigates convergent factors associated with occupational stress among General Hospital Administrative Staff(GHAS). The survey was administered to 221 staffs from 11 general hospitals located in J city from November 1st, 2016 to January 31st, 2017, using structured self-administered questionaries without respondents' personal information. The hierarchical multiple regression analysis shows the following results. The occupational stress of respondents turned out to be significantly higher in following groups: a group in which organizational justice-distributive is lower, a group in which self-esteem is lower, a group in which self-efficacy is lower. The results show explanatory power of 39.5%. The results of the study indicate that the efforts, to increase organizational justice-distributive, to increase self-esteem, to increase self- efficacy, are required to decrease the occupational stress among GHAS. These results are expected to be utilized for organizational and personnel management to reduce occupational stress in GHAS. In the following study, the research of additional factors and the analysis of structural equation model about the occupational stress among GHAS will be needed.

The purpose of study was to test the effects of CEO' transformational leadership and learning organization on innovative behavior in the Knowledge-based Service Organization showing the characteristics of convergence service and the moderating role of learning organization between transformational leadership and innovative behavior. For this study, the data were collected from 348 Knowledge-based Service industrial employees in metropolitan area by using structured questionnaires. Collected data were analyzed by hierarchical regression technique. The results showed that both of CEO' transformational leadership and seven learning organization building factors had a positive effect on employees' innovative behavior. And also found out the only four out of the seven learning organization building factors, namely 'Create continuous learning opportunities', 'Promote inquiry and dialogue', 'Encourage collaboration and team learning', 'Provide strategic leadership for learning' had the moderate roles between CEO's transformational leadership and employees' innovative behavior. The theoretical and practical implications of the findings were discussed and the directions for future research were presented.
