Promoted in places like Korea, the central government and the local governments that can provide information on which to base investment policy to attract foreign direct mutation-specific gravity model (Shift-Share Model) In this study, the decrease of foreign direct investment performance using factors looked up in the industry. The sample period of 2009, 2010, 2011 nationwide (metropolitan and non-metropolitan separated) of foreign direct investment performance for Industry Standard Industrial Classification (Division) was conducted. Factors to look at the results of the National Growth Effect(NS), the industrial structure effect (IM), local allocation effect(RS) to decrease foreign direct investment in 2010 and 2011 non-metropolitan, metropolitan national growth effect(RS) is negative(-) has a value. Because it appears to be the aftermath of the global recession, the impact on the domestic economy Metropolitan area and the Industrial Mix Effect(IM) to the development of education, culture, business, and transportation, etc. in the development of service industries than in non-metropolitan valid environment. In the sector of services (food accommodation, business services, entertainment), We did it, was able to find the function. However, the Regional Share Effect(RS) be competitive in the manufacturing sector in metropolitan areas in the metal and chemical sectors have been identified. These results seems to enhance the competitiveness of the region, such as the metropolitan area's excellent workforce. Shift-Share analysis technique based on competitive factors of the region, to find the failure has limitations.

The purpose of the current study was to validate Fetzer Institute & National Institute on Aging Working Group[NIA](1999)'s Brief-Multidimensional Measure of Religiousness/Spirituality Scale (BMMRS) in Korean adults. The Korean version of BMMRS, Spiritual Well-Being Scale(SWS), Korean Sprituality Scale(KSS), Penn State Worry Questionnaire(PSWQ), and Intolerance of uncertainty Scale(IUS) were administered to the 286 students and community samples. A principle axis factoring analysis with direct oblimin rotation and Kaiser normalization identified a six-factor solution accounting for 66.24% of the variance in scores, labeled as: positive spiritual experience, negative spiritual experience, forgiveness, religious practices, negative congregational support, and positive congregational support. Confirmatory factor analysis results showed that 6 factor model of BMMRS have a good fitness. Also, the internal consistency(.64~.97) and the test-retest reliablity was adequate.(.72~.88) Korean version of BMMRS has adequate psychometric characteristics so it can be used to verify the effects of various compassion-related psychotherapeutic approaches.

Sub 100 nm의 Complementary Metal-Oxide-Semiconductor (CMOS) 소자를 구동하기 위해서는 2.0 nm 이하의 $SiO_2$ oxide에 해당하는 전기적 특성이 요구된다. 그러나 2.0 nm 이하의 $SiO_2$에서는 누설 전류가 너무 크기 때문에 이를 대체하기 위해서 유전 상수 (dielectric permittivity)가 높은 $HfO_2$ (${\varepsilon}=25$), $Al_2O_3$, $HfO_2/Al_2O_3$ laminate 등의 high-k dielectric 물질들이 연구되고 있다[1]. High-k dielectric 물질의 전기적 특성은 박막 조성, 두께 및 전극과의 계면에 생성되는 계면 층이나 불순물(Impurity) 거동에 크게 의존하므로 High-k dielectric/전극(Metal or Si) 구조에서 조성 및 불순물의 거동에 대한 정확한 평가가 주요 쟁점으로 부각되고 있다. 이를 평가하기 위해 일반적으로 $Ar^+$ ion에 의한 depth profiling 분석이 진행되나 Oxygen 원자의 선택적 식각에 기인된 분석 깊이 분해능(Depth Resolution) 왜곡으로 계면 층의 형성이나 불순물의 거동을 정확하게 평가할 수 없다. 이러한 예로는 $Ta_2O_5$ 및 $SrBi_2Ta_2O_9$와 같은 다 성분 계 산화막에 $Ar^+$ ion 주사 시 발생하는 선택적인 식각(Preferential Sputtering) 때문에 박막의 실제 조성 및 거동을 평가하는 것은 어렵다고 보고된 바 있다[2,3]. 본 연구에서는 $90{\AA}$인 적층 $Hf_xO_y/Al_xO_y/Hf_xO_y$ 구조에서의 불순물 거동 분석 능력 확보 상 주요 인자인 깊이 분해능 개선을 Secondary Ion Mass Spectroscopy(SIMS)의 primary ion 종, impact energy 및 주사 각도를 변화시켜 ~1 nm 수준까지 구현하였다. 이러한 분석 깊이 분해능의 개선은 Low Impact Energy, 입사 이온의 glancing angle 및 Cluster ion 적용에 의존하며 이들 요인의 효과에 대해 비교/고찰하고자 한다.

This study made linked Energy IO Table 00-05-08 of 76 sectors in intermediate sectors and analyzed structural decomposition analysis in energy consumption change in industrial sector with both by aggregate data and micro data. Structural decomposition analysis focused value added level change, value added share change of each industry, output structural change of each industry and energy intensity change of each industry as factors. Supply side model based on Ghosh inverse matrix was applied as empirical model because Korea has export driven industrial structure. Empirical results with aggregate data showed that value added change increased energy consumption and output structural change of each industry decreased energy consumption in both 2000~2005 and 2005~2008. However value added share change and energy intensity change caused opposite direction in energy consumption change with time. Policy based on aggregate data can not evaluate effort of each industry in energy efficiency and make effective results because aggregate data delete character of each industry.

The present study empirically confirmed Korean elder's four major pains consisted of poverty, disease, role loss, loneliness and investigated the mediating role of depression between the four major pains and the elder's suicidal thought. To investigate the cause and effect of factors, we conveniently collected 309 samples from 16 Gyungrodangs evenly located in Jeonju and 291 samples, survived the data cleaning such as missing values, outliers, normality and covariance conditions, were analyzed by frequency, factor analysis, reliability, confirmatory factor analysis and structural model analysis. Followed were the selected contributions of the present study. First, the constructs of four major pains such as poverty, disease, role loss, loneliness were predictors of suicidal thought mediated by depression. Second, the elder's poverty, that was the heaviest factor of the four major pain constructs, was a predictor of role loss leading to loneliness. Third, four major pains were predictors of the elder's depression. Note that poverty were not direct but indirect predictor of depression. The present study confirmed the concept of four major pains. Also those who practice in the area of the elderly care should consider the four major pains as well as depression while intervening in the elderly's suicidal thought.

To meet sectoral emission target by 2020 and prepare for the emission trading scheme from 2015, decomposition analysis of energy consumption and GHG emission is required by 18 subsectors in industry sector where emission targets are established. Log Mean Divisia Index decomposition method was used to analyze factors' effects on energy and emission in the industry sector and by 18 subsectors from 2004 to 2011. Industrial energy consumption was increased due to the production effect and energy intensity effect. However structure effect contributes to the decrease of energy consumption. In terms of emissions (including indirect emission due to electricity consumption) in the industry sector, only structure effect contributed to the emission reduction. Factors' effects by subsectors were different. Cement industry, which is included at Nonmetal shows different results from those of Nonmetal industry and machinery industry, which is a subsector of Fabricated Metal, was also similar. In this regard, we should not apply the policy implications from decomposition analysis of aggregated industry such as Nonmetal or Fabricated Metal to its subsectors uniformly and develop a differentiated policy for each subsector industry.

This study aims to understand how human capital is related to the inter-regional wage gap between the capital region and the non-capital region in Korea. We focus more specifically on whether the inter-regional wage gap is due to high levels of human capital in the capital region or due to high returns to human capital in the capital region. The decomposition method based on the unconditional quantile regression was used to examine how the relationship between human capital and the inter-regional wage gap varies along the wage distribution. When first estimating earnings functions from the two regions to apply this decomposition method, we included not only conventional indicators of human capital, such as education and on-the-job training, but also occupational skills including cognitive-interactive skills, technical skills, and physical skills. As a result, other things being equal, a large part of the inter-regional wage gap was explained by the human capital variables. Although the composition effect of the human capital variables existed in all the wage quantiles, the more important factor was the wage structure effect of the human capital variables. In addition, among the various human capital variables, the wage structure effect of years of education was a key factor in explaining the inter-regional wage gap. This study is meaningful in that it shows that the relationship between human capital and the inter-regional wage gap may vary depending on the wage quantiles.

적외선 소자의 재료로 쓰이는 액상 에피 성장법(Liquid phase epitaxy: LPE)으로 성장된 HgCdTe (MCT)박막의 Hg 분위기 열처리에 따른 구조적 변화를 고 분해능 투과 전자 현미경으로 관찰하였다. 일반적으로 LPE방법으로 성장된 MCT박막은 성장 방법의 특성상 Te 과다 영역의 성장용액이 사용되므로 상온 냉각 과정에서 박막 내 국부적인 Te 석출물을 형성 시킬 가능성이 높다. 또한, 성장 과정시 높은 Hg 증기압으로 인해 Hg-vacancy가 존재하므로 품질을 저하시키는 요인이 된다. 따라서, 본 실험에서는 Hg-vacancy와 국부적인 Te 석출물의 제거를 위해 Hg 분위기 열처리 공정을 실시하여 박막의 결정성 변화 및 국부적인 조성 변화를 관찰하였다. 실험결과, 열처리에 따른 Hg의 박막 내 공급으로 인한 이차상의 형성 등이 관찰 되었으며 부피 팽창으로 인해 격자의 변형이 관찰 되었다. 이는 투과 전자 현미경의 고 분해능 이미지 와 Gaussian mask filtering 기법으로 보여진 격자 줄무늬상 (lattice fringe)으로 확인 하였다. 또한, 열처리에 따른 국부적인 조성 편기의 해소는 high angle annular dark field scanning TEM(HAADF-STEM)을 이용하여 관찰 하였다.

This study defines the biotechnology industry, examines its position in the domestic economy, and analyses its structure with I-O tables of year 1985, 1990 and 1995. Structural decomposition analysis is used in order to estimate the impact of different sources of growth. We classifies Korean biotechnology industry into 6 sectors, based on the survey of domestic biotechnology industry by Bioindustry Association of Korea. Empirical results indicate that each sector of bioindustry has various sources of growth and industrial demand has led the growth in all sectors except for food-bio and agriculture-bio. For the growth of the industry, each sector needs to cope with the change of the private demand and to improve the import and export structure.
