Global warming has mainly occurred from waste energy at combustion process which was one of the cause. Due to this reason, recycling the waste energy technology has developed for years. During combustion process, acid gas which was NOX and SOX etc. was occurred and this was promoted the corrosion. Therefore looking for the suited materials used in heat exchangers, the materials was evaluated in this paper. The materials was Ti/Cu clad which was combined with titanium with high corrosion resistance and copper with high thermal conductivity. Clad materials characteristics depending on manufacture method, thus the clad materials properties according to manufacture method were presented. First, interface of Ti/Cu clad materials which was fabricated by two ways which was cold rolling and explosive welding was evaluated. Interface bonding of cold rolling clad was lower than explosive welding clad a little. However, mechanical properties was better than explosive welding clad. Yield strength and tensile strength of cold rolling clad and explosive welding was 477 MPa, 541 MPa and 314 MPa, 410 MPa respectively. In case of cold rolling, micro Vickers hardness of interface, Ti area and Cu area was 223 Hv, 164 Hv and 116 Hv respectively, but hardness of explosive welding clad was 214 Hv, 135 Hv, 88 Hv respectively. This reason was due to effect of cold working by caused cold rolling. The Corrosion resistance of Ti/Cu clad was following corrosion behavior of Cu. The weight change had a negative number because Cu was dissolved in strong acid.

기독대학생이 지각한 부모의 양육태도와 신앙성숙이 자아정체감에 미치는 영향

박양균 한영신학대학교 상담복지대학원 2011 국내석사

본 연구는 기독 대학생이 지각하는 부모의 양육태도와 신앙성숙의 하위영역, 그리고 자아정체감의 수준이 기독대학생의 일반배경에 따라 차이가 있는지를 알아보고, 기독대학생이 지각한 부모의 양육태도, 신앙성숙, 자아정체감과의 상관관계와 부모의 양육태도와, 신앙성숙이 자아정체감에 미치는 영향에 대하여 검증하고자 하였다. 본 연구에서는 수도권지역에 소재한 4개 교회의 청년 대학부 대학생과, 수도권 모 기독교대학의 학생을 중심으로 216명의 자료를 수집하였고, SPSS 18.0 프로그램을 사용하여 내적 신뢰도(Cronbach α) t검증과 일원분량분석, 상관관계 분석, 회귀분석을 실시하였다. 이러한 과정을 통하여 나타난 연구 결과는 다음과 같다. 첫째, 기독대학생의 일반적 배경에 따른 기독대학생이 지각한 부의 양육태도에서는 부의 수용적 양육태도가 신앙연수, 교회출석시기, 가족신앙상태에 따라 유의한 차이가 있었고, 모의 양육태도에서는 수용적 양육태도가 교회출석시기, 가족신앙상태에 따라 유의한 차이가 있는 것으로 나타났다. 신앙성숙의 하위유형인 신앙고백성에서는 교회출석, 신앙경력에 따라 유의한 차이가 있었고, 교회생활성에서는 월평균 교회 출석, 신앙경력에 유의한 차이가 나타났다. 사회생활성에서는 성별, 신앙경력에 따라 통계적으로 유의한 차이가 있었다. 그러나 기독대학생의 일반적 배경에 따른 자아정체감에는 차이가 없었다. 둘째, 기독대학생이 지각한 부모의 수용적 양육태도는 낮은 정적상관이 있었고, 부모의 거부적 양육태도는 낮은 부적상관을 보였다. 그리고 부모의 양육태도는 신앙성숙의 하위영역인 신앙고백성, 교회생활성, 사회생활성과 낮은 정적 상관이 있는 것으로 나타났다. 셋째, 기독대학생이 지각한 부모의 양육태도와 신앙성숙과 자아정체감관계에서는 부의 수용적 양육태도가 자아정체감에 정적으로 영향을 미치고 있으며, 신앙성숙이 자아정체감의 하위영역인, 교회생활성, 사회생활성이 정적영향을 미치는 것으로 나타났다. 본 연구를 통하여 기독대학생의 지각한 부모의 양육태도와, 신앙성숙이 자아정체감을 높이는 것으로 나타났다. 즉 부모의 양육태도가 거부적 양육태도로 지각될 때보다는 수용적이라고 지각될 때 더 자아정체감에 영향을 주고 있으며, 신앙이 성숙할수록 자아정체감에 영향을 주고 있다는 것을 알 수 있었다. 따라서 제2의 탄생이라고 불리는 이 시기의 기독대학생들의 자아정체감 확립을 돕기 위해서는 부모가 자녀들을 수용적으로 대할 수 있도록 수용적 양육태도에 대한 부모교육 프로그램 개발과 신앙성숙을 도울 수 있는 상담적 접근모델이 필요하다. The study was conducted in order to examine difference in the sub‐factors of parents’ parenting attitude and perceived by Christian university students and the students’ religious maturity and self‐identity level according to the students’ general background, and to analyze the correlation between parents’ parenting attitude perceived by Christian university students and the students’ religious maturity and self‐identity, and the effects of parents’ parenting attitude and religious maturity on self‐identity. For these purposes, we collected data from 216 university students sampled from the Youth and University Part of four churches and a Christian university in the capital area, and analyzed collected data through internal reliability (Cronbach α) t‐test, one‐way ANOVA, correlation analysis and regression analysis using SPSS 18.0. The results obtained from this procedure were as follows. First, as to father’s parenting attitude perceived by Christian university students according to the students’ general background, father’s receptive parenting attitude was significantly different according to the number of years as a Christian, the period of church attendance, and the state of family’s faith. As to mother’s parenting attitude, receptive parenting attitude was significantly different according to the period of church attendance and the state of family’s faith. Confession of faith, one of the sub‐factors of religious maturity, was significantly different according to church attendance and religious experience, and church lifestyle was significantly different according to the monthly average number of church attendances and religious experience. In addition, social lifestyle was statistically significantly different according to gender and religious experience. However, no significant difference was observed in Christian university students’ self‐identity according to their general background. Second, parents’ receptive parenting attitude perceived by Christian university students showed a low positive correlation and parents’ rejective parenting attitude showed a low negative correlation. In addition, parents’ parenting attitude was found to have a low positive correlation with the sub‐factors of religious maturity, namely, confession of faith, church lifestyle, and social lifestyle. Third, as to the relation between parents’ parenting attitude perceived by Christian university students and the students’ religious maturity and self‐identity, father’s receptive parenting attitude had a positive effect on self‐identity, and religious maturity had a positive effect on church lifestyle and social lifestyle among the sub‐factors of self‐identity. According to the results of this study, Christian university students’ self‐identity can be enhanced by parents’ parenting attitude perceived by the students and the students’ religious maturity. That is, the students had stronger self‐identity when they perceived parents’ parenting attitude to be receptive and their religious maturity was high. Accordingly, in order to help university students establish their self‐identity during this period, which is called the 2nd birth, we need to develop parent education programs on receptive parenting attitude so that parents treat their children receptively and to formulate counseling approach models for enhancing religious maturity.

박양균 全南大學校 大學院 1986 국내석사

쌀보리 품종인 송학과 영산 전분의 NaOH 및 KSCN에 의한 cold gelatinization과 리올로지 특성은 품종간에 차이를 보였다. 알칼리 용액에 의한 겉보기 정도와 초기호화속도는 송학이 영산에 비해 낮았으며, 전분 농도와 초기호화속도와의 관계에서 알칼리 농도가 증가 할수록 두 전분간의 초기호화속도의 차가 커졌다. 알칼리 호화에 의한 광투과도에서 송학이 영산 보다 호화 시작 및 완료시간이 걸었으며, KSCN에 의한 겔 부피는 송학이 영산 보다 적었다. 3.5.7및 9% 전분 호화액의 리올로지 특성에서 모두 의가소성의 거동을 냐타냈고, 점조도지수 및 항복응력은 송학이 영산 보다 높았으며 농도 의존성도 컸다. 5% 농도 부근에서는 전분 호화액의 구조적 특성이 달라 졌으며, 활성화에너지는 송학 4.098, 영산 3.710 Kcal/g·mole 이었다. Cold gelatinization with NaOH and KSCN, and rheological properties were investigated in naked barley starches. The two types of barley were Songhak and Youngsan. The apparent viscosity and initial gelatinization rate of Songhak starch treated with NaOH were lower than those of Youngsan starch. As alkaline normality increased, the difference between the initial gelatinization rate for the two types of starch increased at all starch concentrations. The initial and finished gelatinization times of Songhak starch are later than those of Youngsan starch when the transmittance was measured in starch suspension with alkaline gelatinization. Gel volume of Songhak starch treated with KSCN was less than that of Youngsan starch. The two barley starches showed pseudoplastic behavior in 3% ,5%, 7% and 9% starch suspension. The consitstency index, yield stress and effect of starch concentration in Songhak starch were higher than those in Youngsan starch. The structural properties of gelatinized starches changed at 5% starch concentration, and activation energies of starches were 4.098 and 3.710 Kcal/g mole for Songhak and Youngsan barley starches, respectively.

This study seeks to examine the corporate governance and firm performance. Korean corporate governance were changed not by corporation but by government. Before 1997, Korean financial crisis, Korean government focused on the promotion of capital markets and firm's public offerings. After Korean financial crisis, the government has focused to change corporate governance system, to protect minority shareholders and investors, to improve the management transparency, to prohibit the controlling shareholder’s tunnelling, etc. But there are various corporate governance structures that exist around the world. They have been affected by the country-specific political, economical, social, cultural environments. But many policy makers still believe that corporate governance is important for firm’s performance, and the government perseus to change the corporate governance system in 2013. And then I investigates whether a series of recent economic reforms on corporate governance influence the firm’s performance. This study uses the balanced panel data for 235 manufacturing firms listed in KOSPI during 2002-2011. And I sheds light on this question while taking accounting the firm size, SMEs and medium-sized firm, large-sized firms. I find that controlling shareholders decreases the firm performance, but statistically insignificant. In addition, outsider directors have the negative effects of the performance. This empirical result is inconsistent with policy makers opinions, and indicates that corporate governance is not important in corporate performance. And then it implies that policy makers are cautious for the current legal reform and strict enforcement of corporate governance.

박양균 한영신학대학교 대학원 2016 국내박사

본 연구의 목적은 중년기 여성의 자아분화, 사회적지지, 성역할갈등과 자아정체감의 관련성을 살펴보고, 자아분화, 사회적지지와 자아정체감과의 관계에서 성역할갈등의 매개효과를 확인하는 것이다. 이에 선행연구를 토대로 중년기 여성의 자아분화와 사회적지지가 성역할갈등을 매개로 자아정체감에 영향을 미치는 구조모형을 설정하고 검증하였다. 본 연구의 대상자는 서울, 경기, 인천 지역에 거주하는 중년기 여성 320명으로부터 자료를 수집하였다. 연구를 위한 통계방법으로 기술통계, 상관분석, 구조모형검증, 매개효과검증을 실시하였다. 이러한 연구결과는 다음과 같다. 첫째, 주요 변인들은 유의한 상관관계를 나타냈는데, 자아분화와 자아정체감과의 관계는 유의한 정적상관관계가 있었고, 자아분화와 성역할갈등은 유의한 부적상관관계가 있었다. 그리고 성역할갈등과 자아정체감과는 유의한 부적상관관계가 있고, 사회적지지와 성역할갈등은 상관이 없는 것으로 나타났다. 또한 사회적지지와 자아정체감과는 유의한 정적상관관계가 있는 것으로 나타났다. 둘째, 자아분화와 사회적지지가 성역할갈등을 매개로 자아정체감에 미치는 구조모형은 적합한 것으로 나타났다. 또한 자아분화, 사회적지지와 자아정체감의 관계에서 성역할갈등이 매개효과를 갖는지 살펴본 결과, 사회적지지가 성역할갈등을 통해 자아정체감에 영향을 미치는 매개효과는 유의하지 않았고, 자아분화가 성역할갈등을 통해 자아정체감에 영향을 미치는 매개효과는 유의하였다. 그리고 자아분화가 자아정체감에 미치는 직접효과 또한 유의하였다. 따라서 자아분화와 자아정체감과의 관계를 성역할갈등이 부분매개 하는 것으로 나타났다. 중년기 여성의 외적요인(사회적지지)보다 내적요인(자아분화)이 성역할갈등을 통해 자아정체감에 영향력이 있음을 의미한다. 본 연구는 중년기 여성의 자아정체감에 대한 탐색적 연구로 성역할갈등이라는 주요한 매개변인의 발견과 향후 중년기 자아정체감 혼란을 경험하는 여성들의 상담과 교육적 측면에 함의점을 제공하였다는 것에 의미가 있다. This research aims for structural investigation of variables that influence self-identity of middle adulthood. Through theoretical argument, the research herein set up the variables as differentiation of self, social support, and gender-role conflict, and examined whether or not gender -role conflict has a mediating effect on the relationship with self-identity, dependent variable, by making differentiation of self as inner variable of middle adulthood and social support as outer variable for independent variable. In this research, data were collected from 320 female participants in middle adulthood living in Seoul, Gyeonggi, and Incheon regions, and data processing used descriptive statistics, correlation analysis, structural equation modeling, the mediating effects of structural model. Results derived from this process are as follows. First, to investigate the correlation between major variables, the relationship between differentiation of self and self-identity had a significant positive correlation, the relationship between differentiation of self and gender role conflict had a significant negative correlation. Further, the relationship between gender role conflict and self-identity had a significant negative correlation, while the relationship between social support and gender role conflict had no correlation. Further, the relationship between social support and self-identity had a significant positive correlation. Second, results derived from the research on the effect of differentiation of self, and social support on self-identity by the mediating effect of gender role conflict revealed that a structural model where the effect of differentiation of self on self-identity by the mediating effect of gender role conflict had a significant mediating effect by the mediating variable of gender role conflict, and the direct effect of differentiation of self on self-identity was also significant. Gender role conflict served as partial mediator of differentiation of self and self-identity. Meanwhile, gender role conflict had no mediating effect on the relationship between social support and self-identity, and no significance in directly affecting social support and self-identity. For the factors that influence self-identity of middle adulthood, inner factors were more significant than outer factors, and the mediating effect of gender role conflict was also significant only in the relationship with differentiation of self, inner variable. This research has its significance in that it is a probe study on the self-identity of middle adulthood, offering findings of a major mediating variable which is gender role conflict, counseling of female clients experiencing conflict of self-identity of middle adulthood, and implicit points in educational aspects.
