Objective : The objective of this study is to create questionnaires for Social Capital (SCQ) and Built Environment (BEQ) that can be utilized as protective factors for mental health. Methods : A total of 426 adults aged 18 or older, residing in 'D' Metropolitan City in Korea, were included as subjects in this study. Data for subjective evaluation of social capital and built environment were collected through an online survey. Various statistical analyses, such as reliability analysis, exploratory factor analysis, confirmatory factor analysis, and correlation analysis between PHQ-9 and GAD-7, were conducted. Results : The Cronbach's α values for SCQ and BEQ were 0.94 and 0.90, respectively, indicating good reliability. Exploratory factor analysis revealed that SCQ consisted of 4 factors, explaining a total of 71.91%, while BEQ consisted of 4 factors, explaining a total of 62.18%. Confirmatory factor analysis confirmed that both questionnaires had a reasonable configuration, with TLI, CFI, and RMSEA values at an appropriate level. Additionally, both SCQ and BEQ showed negative correlations with depression and anxiety. Conclusion : This study has developed a tool for measuring social capital and the built environment in Korea. It also demonstrates the reliability and validity of this questionnaire. The use of this tool could greatly support preventive mental health interventions within the community.

아미드-아미드 및 아미드-용매 상호작용에 관한 Raman 분광학적인 연구
유정아,최영상,Jeong-A Yu,Young-Sang Choi 대한화학회 1983 대한화학회지 Vol.27 No.6
Raman spectra for the carbonyl stretching mode of the amides, and amide-solvent systems have been recorded to investigate the effect of alkyl substitutions at the carbonyl carbon and at the nitrogen on the amide hydrogen-bonding. The data have shown that the interaction affinities are in the order of amide-amide > amide-water > amide-alcohol in formamide system, and amide-water > amide-amide > amide-alcohol in acetamide and propionamide systems. The strength of the proton acceptor of the carbonyl oxygen is increased by the presence of alkyl group to the carbonyl carbon and the proton donorcity of the amide is decreased by the alkyl substitution at the nitrogen. The above results are in good agreement with the ab initio SCF MO calculation. 아미드와 아미드-용매계의 C=O stretching band에 해당하는 Raman 스펙트럼으로 부터 카르보닐기와 질소에 치환된 알킬기가 수소결합에 미치는 영향을 조사하였다. Formamide 계에서는 상호작용의 세기가 아미드-아미드>아미드-물>아미드-알코올 순으로 감소했으며, acetamide와 propionamide 계에서는 아미드-물>아미드-아미드>아미드-알코올 순으로 감소하였다. 카르보닐기에 알킬기가 치환되면 카르보닐기의 proton acceptor의 세기가 증가되며, 질소에 알킬기가 치환되면 proton donorcity가 감소함을 보이는데 이는 이론적인 계산 결과와도 일치한다.

Little is known about reemployed workers` job quality in Korean labor market. This paper attempts to examine the predictors influencing reemployed workers job quality(reemp1oyment pattern and wage level) by using the data set of 2001 Korean Labor and Income Panel Study. Logistic regression analysis is adopted to identify variables predicting reemployment pattern and multiple regression analysis is adopted to identify variables predicting wage level. For the reemployment pattern, this paper has the following results: sex(male), education (college), prior social security income(+), transfer income(-), prior employment pattern(tenured employment), reasons (voluntary resignation) for unemployment, and unemployment duration(+) are the predictors. On the other hand, for the reemployment wage level, this paper has the following results: sex(male), age(+), age square(-), education(high school and college), prior transfer income(-), prior employment wage, and unemployment duration(+) are the predictors. This paper provides discussions about the structural problems of fragmented labor market in Korea. This paper contributes to expanding and deepening knowledge body about the realities of Korean reemployed workers` job quality in the economic recovery period of Korea. Finally, this paper identifies research areas for further research and develop policy implications for the reemployed workers taking low quality jobs in the labor market.

Purpose: This study aimed to develop an IRT Program in order to train the cadets of the AFNA as prospective military nursing officers to be completely ready to perform their duty under any circumstances in the field. Methods: This study was conducted using a competency-based curriculum development model with four phases. In the analysis phase the educational demands were identified by literature review and interviews with the cadets and nursing officers. In the planning phase based on the data collected in the first step the educational contents were extracted and the educational goals were set with expert reviews. In the development phase a competency profile was made up of key competencies required for the readiness and based on that the IRT Program was developed. The application and evaluation phase was intentionally omitted due to the time frame. Results : The competency profile consisted of 55 competencies which were classified into five categories : Leadership included six competencies such as conflict management and crisis communication ; Medical equipment management skill was comprised of 16 competencies including skills to deal with defibrillators and portable suction devices ; Emergency and trauma care involved 26 nursing care skills including treating gunshot wounds ; Evacuation care included four competencies which were essential while evacuating patients ; Mass casualty management consisted of three competencies including triage. The IRT Program was designed to promote each trainee to achieve the educational goals step by step with self-assessment of their own competency level and accomplishments. Conclusion: This study is expected to contribute to improving and strengthening the cadets` field readiness.

2015 개정 교육과정에 따른 화학 Ⅱ 교과서의 본문에 서술된 과학지식의 특성: 법칙, 이론, 가설, 원리, 모형을 중심으로
유정아 ( Jeong-a Yu ) 한국현장과학교육학회 2020 현장과학교육 Vol.14 No.1
과학지식은 탐구의 산물임과 그 생산 과정을 내포한다. 2015 개정 교육과정에 기초한 화학 Ⅱ 교과서 6종의 본문 텍스트에 서술된 법칙, 이론, 가설, 원리, 모형이 제시하는 과학지식의 특성을 분석하였다. 분석결과 각 교과서는 5개~9개의 법칙과 르샤틀리에 원리를, 그리고 일부 교과서에서 기체 분자 운동론, 아보가드로 가설, 소수의 모형을 다루고 있었다. 법칙의 특성으로 특정 조건, 규칙성 및 패턴 발견, 변인간의 인과 관계가 서술되었고, 일반화 과정의 명시적 언급은 없으며, 관찰기반은 일부 법칙에 한하여 서술되었다. 기체 법칙은 적용한계를 제시하지 않아 이어지는 탐구활동의 역할을 제한할 수 있겠다. 또한 관측 자료의 외삽에 의한 예측 구간에 대한 서술은 부족했다. 르샤틀리에 원리는 교과서에 따라 원리와 법칙을 같은 개념 혹은 원리를 보다 넓은 개념으로 이해하게 했다. 기체 분자 운동론은 이론의 제한점을 제시하고, 기체 법칙이나 관찰된 변인의 인과 관계를 분자의 운동으로 설명하는데 한정됐다. 충돌론과 기체 분자 운동론에 기초하고 있음을 명시하지 않고 이들 이론으로 반응 속도를 설명하여, 학생들은 ‘설명’과 ‘사실’을 구분하기 어렵겠다. 아보가드로 가설은 무엇을 설명하기 위한 가설인지 알 수 없었고, 검증 과정을 거쳐 혹은 시간이 지난 후 ‘저절로’ 법칙이 되는 것으로 표현하여 선택한 교과서에 따라 가설에 대한 오개념을 가질 수 있겠다. 모형은 설명하는 현상을 제시하고 있었으나, 기반이 되는 이론의 명시적 언급은 없었다. 종합하면 본문 텍스트는 내용 지식 이외에 과학지식의 특성에 대한 충분한 정보를 제공하고 있지 않았다. 이를 바탕으로 학교현장 수업에서 강조할 부분과 보완할 부분에 대하여 논의하였다. Scientific knowledge is the product of inquiry and its production process. The body texts of six Chemistry Ⅱ textbooks developed under 2015 revised curriculum were examined to analyze how the theories, laws, principles, hypotheses, and models reflect the characteristics of each term. It was found that five to nine laws and LeChatlier’s principle were covered. and some textbooks covered gas kinetic theory, Avogadro’s hypothesis, and few models. The nature of the law is described in terms of specific conditions, regularity and pattern discovery, causality between variables, and descriptions of observation-based are limited to a few laws. The generalization processes of the laws are not explicitly mentioned. Gas’s laws did not specify limitations of the law, which could limit the roles of scientific inquiry. Also, the region of prediction by extrapolation of observed is described deficiently According to the textbooks, Le Chatelier’s Principle have led students to understand principles and laws as the same or broader terms than laws. Gas kinetic theory is suggested the limitation of the theory and is limited to explaining the laws of gas or the causal relationship of observed variables with the motion of molecules. It might be difficult for students to distinguish between ‘explanations’ and ‘facts’ by explaining reaction rates, without specifying that they are based on collision theory and gas kinetic theory. The Avogadro’s hypothesis does not explicitly state what the hypothesis explains. According to textbooks, the hypothesis become the ‘law’ when scientifically naturally after the lapse of time without verification Therefore, depending on the textbook chosen, students may have misconceptions about the hypothesis. The models presented explanatory phenomena, and there was no explicit mention of the underlying theories. Taken together, the body texts did not provide enough information about the characteristics of scientific knowledge in addition to content knowledge. Based on these results, the emphasis and complementary points were discussed from the aspects of teaching Chemistry Ⅱ in classroom.
