The purpose of this study was to develop a tolerance promotion program for middle school students and to examine its effect. The following research questions were posed to serve the purpose: 1. Is it possible to construct a tolerance promotion program geared toward middle school students in a valid manner? 2. Is it possible to prove the effectiveness of the tolerance promotion program geared toward middle school students in an experiential way? The subjects in this study were 33 students who were in their first and second year at middle schools respectively located in the cities of G and S, South Jeolla Province. After they were randomly divided into three groups of 11 students each, two groups were selected as the experimental groups that were respectively going to participate in the tolerance promotion program and the self-regulation program, and the third was selected as a control group. The instrument used to address the research questions was Kim Sung-hyun(2011)'s Tolerance Scale for Youth that was based on tolerance theories and techniques of earlier studies. The tolerance promotion program for middle school students was built on Kim Sung-hyun(2010)'s DMCCP. To address the research questions, the statistical package for the social science SPSS/WIN 15.0 was employed. The findings of the study on the research questions were as follows: 1. The tolerance promotion program for middle school students was constructed in a valid way in order to improve the tolerance of middle school students. 2. The tolerance promotion program for middle school students was found to improve the tolerance of the middle school students, and that consequently turned out effective. The significance of this study could be described as below: First, the tolerance promotion program for middle school students that was developed in this study is expected to be of use for the improvement of the tolerance of middle schoolers who face difficulties in interpersonal relationships or are in conflicts with others. Second, the tolerance promotion program for middle school students that was developed in this study is expected to prevent possible interpersonal conflicts at school, to relieve students of egoism and to improve their interpersonal relationships. 본 연구의 목적은 중학생용 관용성 증진 프로그램을 개발하고 그 효과를 검증하는 것이었다. 이러한 연구목적을 달성하기 위해 설정한 연구문제는 다음과 같다. 첫째, 중학생용 관용성 증진 프로그램은 타당하게 구성하여 경험적으로 그 효과성이 검증될 것인가 이었다. 둘째, 중학생용 관용성 증진 프로그램은 관용성 전체 및 각 하위요인(타인존중, 개방성, 자기조절)을 증진시킬 수 있을 것인가 이었다. 이를 위해 본 연구에서는 맞춤형 상담 프로그램 개발 모형(DMCCP: 12단계)을 근거하여 연구목적과 내용에 부합되도록 수정 및 보완하여 구안된 중학생용 관용성 증진 프로그램 개발 모형에 따라 프로그램을 구성하고 개발하였다. 본 연구의 대상은 전라남도 G시와 S시에 재학 중인 중학교 1-2학년 남․여 학생 33명이었고, 각각 11명씩 3개 집단으로 무선배치한 후에 2개 집단을 실험집단(관용성 증진 집단), 비교집단(자기조절 집단)으로 설정하고 나머지 1개 집단을 통제집단으로 설정하였다. 본 연구에서는 중학생용 관용성 증진 프로그램의 효과검증과 프로그램 자체에 대한 평가를 실시하기 위해 사용된 평가 도구와 분석방법은 측정시기별(사전-사후-추후 1-추후 2)로 청소년용 관용성 척도(김성현, 2011), 자기통제력 척도를 이용하여 수집한 자료에 대해 일원 및 이원분산분석을 실시하여 검증하였다. 본 연구의 결과는 연구문제별로 제시하면 다음과 같다. 첫째, 중학생용 관용성 증진 프로그램은 중학생용 관용성 증진 프로그램 개발 모형에 따라 체계적이고 순환성을 보완하여 개발되었기에 그 타당성이 확보되었다고 볼 수 있다. 둘째, 중학생용 관용성 증진 프로그램은 관용성 전체 및 각 하위영역(타인존중, 개방성, 자기조절)에서 실험집단(관용성 집단)이 통제집단보다 중학생들의 관용성을 증진하는 것으로 나타났으며, 실험집단이 비교집단(자기조절 집단)보다도 중학생들의 관용성을 증진시키는데 효과가 있는 것으로 나타났다. 마지막으로, 본 연구의 제한점 및 추후연구의 시사점을 논의하였다.

H∞ Output-Feedback LPV Control for Systems with Input Saturation

김성현 제어·로봇·시스템학회 2012 International Journal of Control, Automation, and Vol.10 No.6

This paper investigates the problem of designing a dynamic H∞ output-feedback controller under an L∞ performance representing componentwise input constraints. In order to derive a less conservative stabilization condition therein, this paper introduces a Lyapunov function-based polytopic control law and proposes a method capable of applying the information on interpolation parameters appearing in the procedure of representing saturation nonlinearity as convex polytope. Through this paper, the resultant H∞ /L∞ problem is efficiently solved based on the set invariance condition formulated in terms of linear matrix inequalities (LMIs).

일반균형동학모형을 이용한 국가채무 증가의 거시경제적 영향분석

김성현,김소영 한국계량경제학회 2013 계량경제학보 Vol.24 No.4

This paper uses a dynamic general equilibrium model with government sector and analyzes short-run and long-run macroeconomic effects of government debt caused by either increases in government spending or decreases in various tax rates. The simulation results suggest several channels that government debt can negatively affect the economy: First, liquidity premium caused by an increase in government debt increases interest rate and decreases investment, and therefore lowers output and welfare in the long run. This is the most significant negative channel in this model. Second, when government spending builds up public capital, an increase in government debt temporarily crowds out private sector capital, which reduces output and welfare in the short run. Third, when government spending affects neither public sector capital nor household utility, an increase in government debt reduces consumption and increases labor input, thereby reducing social welfare. In addition, if the increase in government debt is caused by a decrease in tax rates, positive effects can dominate. 본 연구는 정부 부문을 포함한 일반 균형 동학 모형을 이용하여 정부 소비와 투자 지출의 증가, 소비 및 소득 세율의 감소 등으로 인한 국가 채무의 증가가 중장기적으로 경제에 미치는 영향을 분석하였다. 정부 지출 증가에 따른 국가 채무의 증가는 다음의 경로로 경제에 부(-)의 영향을 미칠 수 있다.첫째, 재정 적자로 인한 유동성 할증은 이자율을 상승시키고 투자를 구축시켜 중장기적으로 생산량을 감소시키고 경제의 후생을 악화시킬 수 있다. 시뮬레이션에 따르면 0.5%의 이자율 상승을 일으키는 정부지출의 증가는 (GDP대비 10%) 장기적으로 생산량을 4.7% 가량 감소시킬 수 있다. 둘째, 정부 투자 지출이 공공 자본을 형성하는 경우 정부 투자 지출의 증가는 단기적으로 민간 자본을 대체하게 되고 소비와 후생을 감소시킬 수 있다. 셋째, 공공 자본 축적에 도움이 안되고 가계의 효용에 직접적으로 영향을 미치지 못하는 정부 지출의 증가는 소비를 감소시키고 노동 투입을 증가시켜 경제 전체의 후생을 감소시킬 수 있다. 하지만 세율의 감소에 의한 국가 채무의 증가는 일반적으로 정부 지출에 의한 국가 채무 증가의 경우보다 정(+)의 효과가 크다.

우리나라의 輸入市場構造가 國內物價에 미친 影響

金成炫 漢陽大學校 1972 論文集 Vol.6 No.-

In order to achieve the goal of economic growth envisioned in the Five year Economic Development Planning initiated in 1962, raw materials and equipment of diverse kinds have been brought over from overseas in great guantities. As a result, the differences on demand and supply of raw materials and the fluctuation of their import prices have excerted a great deal of influence on the prices of the domestic products. This paper classifies the influx structure of imported generally. These four categories determine the influx structure of the imported goods depending on what kinds of goods they are. Then the paper discusses in general terms the structure of Price fluctuations and then explains the discrepancy between the wholesale price index and the consumer price index so as to clarify the trend of the wholesale prices on imported goods. in further explains the relationship between the market structure and the price fluctuations, and while discussing the various problems of the influx margin on imported good, tries to show how margin is formed through the intermediate process of influx by the time each of the imported goods reaches the consumer through the adovementioned four influx routes and how intimately, this is related to the upward of domestic price indexes.

Controlling Charge Transport by Using a Mixed Hole Transport Layer in Phosphorescent Organic Light-emitting Diodes

김성현,송기국 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.62 No.2

The device performances of green phosphorescent organic light-emitting diodes (PHOLEDs) with a mixed hole transport layer (HTL) and either of two host materials were compared as a function of the mixed HTL composition. The mixed HTL was prepared using N,N’-di(1-naphthyl)-N,N’- diphenylbenzidine (NPB) and 4,4’,4”-tris(N-carbazolyl)triphenylamine (TCTA), which were combined with either a hole-transport-type host material, (4,4’-N,N’-dicarbazole)biphenyl (CBP) or an electron-transport-type host material, PH1. The maximum quantum efficiency of the PHOLEDs was attributed to the charge balance in the emitting layer (EML) and to the blocking of the triplet excitons caused by increasing TCTA composition in the mixed HTL.

Synthesis and Characterization of Nanocrystalline Yttria-stabilized Zirconia for an Electrolyte in a Solid-oxide Fuel Cell

김성현,G. Y. Jin,M. Kim,양용석 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.61 No.6

We synthesized various sizes of nanocrystalline yttria-stabilized zirconia (YSZ) for an electrolyte in solid-oxide fuel cell (SOFC) by using the sol-gel method. The surface morphology and the thermomechanical properties for different nano-grain sizes were characterized. The YSZ grains were found to grow non-linearly, as well as non-logarithmically, with increasing sintering temperature. The surface morphology shows that the grains of nano-sized YSZ are well dispersed in the measured area, with a narrow size distribution and without significant aggregation. The values of the thermal expansion coefficient of nano-grain YSZ obtained in this study are close to those of the other components of the electrodes and the interconnects used in the SOFC. The effect of the grain size on the thermo-mechanical property is also found to be negligible.

An artificial diet for the swallowtail butterfly, Papilio xuthus

김성현,홍성진,박해철,이영보,박관호,최원호,김남정 한국잠사학회 2014 International Journal of Industrial Entomology Vol.28 No.1

The effect of an artificial diet on developmental rate, a life history parameter, was examinedfor the swallowtail butterfly Papilio xuthus. Artificial insect diets are an essential componentof many insect rearing systems that produce insects for research purposes. Complex agargelleddiets are generally prepared in large batches and used shortly after preparationbecause the degradation of perishable diet ingredients, such as vitamins and fatty acids,can adversely affect insect quality (Brewer 1984). However, the timing of diet preparationmay be inconvenient, and large batches wasteful, if the unused excess is discarded. Thepercentage of pupation varied considerably, with no significant differences among diets,on which a maximum pupation percentage of 83% was observed. Pellet-type diets wereinvestigated with the aim of developing a more easily prepared diet. The extrusion of theartificial diet under high temperature and pressure may induce desirable chemical andphysical changes in the extruded product. The purpose of the present study was to developan artificial diet for rearing P. xuthus.

Effect of temperature on the development of the Common Grass Yellow, Eurema hecabe

김성현,박해철,박인균 한국잠사학회 2015 International Journal of Industrial Entomology Vol.31 No.2

The developmental responses of insects to temperature are important considerations in gaining a better understanding of their ecology and life histories. Temperature-dependent phenology models permit examination of the effects of temperature on the geographical distributions, population dynamics, and management of insects. Measurements of insect developmental and survival responses to temperature pose practical challenges that depend on the chosen modality, variability among individuals, and high mortality rates near the lower and upper threshold temperatures. Different temperature levels can significantly affect larval development of Eurema hecabe. The development of E. hecabe reared on leaves of Lespedeza cuneata was investigated at three temperature regimes (20, 25, and 30°C), a relative humidity of 60%, and a light:dark photoperiod of 14:10 h. The developmental time from larva to adult was 34.3, 20.6, and 17.9 d at temperatures of 20, 25, and 30°C, respectively. Pupal rate was 47.6%, 47.6%, and 61.9% at temperatures of 20, 25, and 30°C, respectively. The developmental threshold temperature estimated from larva to pupae was 8.1°C with 381.7 degree-days. There is an increasing need for a standardized manual for rearing this butterfly species based on adequate knowledge of its ecology

Credit Rationing and Signalling Effects of Trade Credit: Theory and Evidence from Korean Firms

김성현,Sang Ah Lee 한국계량경제학회 2014 계량경제학보 Vol.25 No.4

We examine interaction among bank credit, trade credit and internal wealth. Our theoretical model derives borrowers' optimal patterns of credit uses depending on internal wealth levels, subject to credit rationing. In particular, the model incorporates signalling effects of and nonlinear interest schedules for trade credit to account for stylized facts from Korean data that are at odds with previous models. Our empirical results are broadly consistent with presence of signalling effects as well as theoretically predicted interaction patterns. The results could be interpreted as a rough estimate of the extent of credit rationing among sample firms.
