심부 처분환경조건에서 붕규산유리고화체의 장기침출거동을 규명하기 위하여 3종의 모의붕규산유리고화체에 대한 장기침출실험이 1997년에 착수되었다. 5년간의 침출결과는 붕소가 본 붕규산유리고화체의 장기침출지표물질로 사용될 수 있음을 확인시켜 주었고, 비록 고화체들의 조성은 약간씩 다르지만, 초기 1년여 기간동안의 침출률을 제외한 장기침출률은 S/V에도 무관하게 0.03g/$m^2$-day 에 근접하는 경향을 보여주고 있다.

본 논문은 차등 RSSI(DRSSI: Differential Received Signal Strength Indicator)를 이용하여 자원을 효율적으로 사용할 수 있는 핸드오프 처리 방안에 대해 제안한다. DRSSI는 이동국의 이동 방향을 예측하는데 사용할 수 있다. 즉, 이동국의 움직임이 바뀌는 경우 DRSSI의 극성(+, -)이 바뀌는 특성을 이용하여 이동국이 셀 사이의 중첩 지역에 머무는 동안 극성의 변화를 우선적으로 판단하여 다수의 단말기의 방향을 예측함으로써 핸드오프 및 자원을 예약할 이동국을 예측하고, 자원의 우선적인 사용권을 부여하는 방안을 제시하여 자원의 유효 상태를 극대화하는 방안을 제시한다. 또한, 수학적 모델링 분석을 통해 핸드오프 차단 확률이 기존의 방법보다 우수함을 보여준다.

새로 분류된 잠재노동력을 유휴노동력에 포함시켜 산출한 고용보조지표와 실업률의 차이를 밝히기 위해 미취업자를 실업자, 잠재노동력 및 이외 비노동력으로 분류하고 노동시장 행태를 분석하여 분류 간 차별성 여부를 파악하였다. 노동시장 상태간 연간 이행률을 토대로 노동력 진입 및 이탈 행태에서 잠재노동력은 이외 비노동력과 다르며 일하려는 욕구가 작지 않은 유휴노동력임을 확인하였다. 인적 특성을 통제한 다항로짓모형 분석 결과는 잠재노동력과 실업자가 동일 집단이라는 가설을 기각하여 고용보조지표와 실업률을 동일 관점에서 해석할 수 없다는 것을 확인하였다.

본 연구는 공공도서관 사서들의 혁신행동이 조직 성과인 서비스 품질에 미치는 영향을 분석하였다. 이를 위하여 본 연구는 수도권 공공도서관 7곳의 사서 및 이용자를 대상으로 설문조사를 실시하여 사서 데이터 77건, 이용자 데이터 309건을 분석 대상으로 삼았다. 사서를 대상으로 혁신행동을, 이용자를 대상으로 서비스 품질을 조사하였다. 분석 결과, 혁신행동의 완성 단계인 아이디어 구현은 정보통제 차원에 정적(+) 영향을 미치는 것으로 나타났다. 다만, 혁신행동의 첫 단계인 아이디어 생성은 서비스의 영향력과 정보통제 차원에 부적(-) 영향을 미치는 것으로 나타났다. 아이디어 생성에 머무르고 아이디어 홍보와 구현 등 다음 단계로 나아가지 않는 상황은 서비스 품질을 저하시키는 것으로 해석되었다. 본 연구는 공공도서관에 혁신행동 개념을 적용하였으며 공공도서관 사서들의 혁신행동이 서비스 품질에 미치는 영향을 실증 연구를 통해 제시하였다는 데에서 의의를 찾을 수 있다.

While health information-seeking behavior as an indicator of health communication of patients including cancer survivors has been researched, few studies have focused on how socioeconomic position and media use combine to influence health-related information seekers. This study examined social characteristics of health information-seeking behavior taking into account an individual's socioeconomic position and their media use in Korea, a developed country. The data for this study came from a survey of 1,010 respondents drawn from a nationally representative sample in the Republic of Korea. We conducted multivariate logistic regression analyses for gender-specific effects. We found that men who reported high household income were one and half times more likely to seek health information than those with low income status. We also found that women who performed Internet searches by computer at home were almost two times more likely to seek health information than those who did not. Similar results were found for men as well. Our analyses revealed that socioeconomic position and media use are associated with health information-seeking behavior by gender. Studies on information seekers may bring us more effective health promotion and relevant intervention for people with chronic conditions including cancer survivors.

The purposes of this study were to find the difference of clothing life-style and to examine clothing buying behaviors on personality types. Personality types were identified using Myers-Briggs Type indicator(MBTI). The data were collected from 360 female adults using a questionnaire to clothing lifestyle and clothing buying behavior. The data were analysed with factor analysis, one- way ANOVA and Duncan＇s multiple range test. Results are summarized as follows: First, ＇Fashion-oriented＇, ＇self-regulate-oriented＇, ＇activity-oriented＇, ＇economic-oriented＇, ＇social-oriented＇, ＇leisure-oriented＇ and ＇conservationoriented＇ clothing life-style had a significant difference of psychological types. Second, Extroverted(E) or Sensation(S) or Feeling(F) types regarded significantly higher in ＇VMD＇, ＇store atmosphere＇, ＇famous brand name and store name＇ as criteria for store selection than combination types(IN, IT, NT) of Introverted(Ⅰ), iNtuition(N), Thinking(T). Third, Sensation Judgement types(SJs) of a patron temperament preferred a ＇plan-oriented＇ life-style and considered ＇famous brand name and store name＇ important. Sensation Perceiving types(SPs) of an artist temperament had an ＇unplanned＇ clothing life-style and a significantly higher impulsive buying orientation than SJs.

The detection of human behavior from social media revolutionized health, business, criminal and political prediction. Significance of it, in incentive transformation of public opinion had already proven for developed countries in improving democratic process of elections. In $3^{rd}$ World countries, voters poll votes for personal interests being unaware of party manifesto or national interest. These issues can be addressed by social media, resulting as ongoing process of improvement for presently adopted electoral procedures. On the optimistic side, people of such countries applied social media to garner support and campaign for political parties in General Elections. Political leaders, parties, and people empowered themselves with social media, in disseminating party's agenda and advocacy of party's ideology on social media without much campaigning cost. To study effectiveness of social media inferred from individual's political behavior, large scale analysis, sentiment detection & tweet classification was done in order to classify, predict and forecast election results. The experimental results depicts that social media content can be used as an effective indicator for capturing political behaviors of different parties positive, negative and neutral behavior of the party followers as well as party campaign impact can be predicted from the analysis.

Objectives: This study was performed to identify the socioeconomic factors, the psychosocial factors and the heath behavior factors that have an influence on abdominal obesity, as measured by using the waist circumference. Methods: Data was obtained from individuals aged above 20 years who had their waist circumference measured on the Korean National Health and Nutrition Examination Survey 2001, which was a cross-sectional health survey. Results: Regression analysis of the factors that affect abdominal obesity showed that the education level, income, smoking, duration of smoking, drinking consumption, frequency of exercises and sleeping were the associated factors for abdominal obesity. For men, the duration of smoking, education level, income and drinking consumption were the associated factors for abdominal obesity. For woman, the education level, income, duration of smoking, drinking consumption and frequency of exercise were the associated factors for abdominal obesity. Conclusions: Abdominal obesity is a risk factor for morbidity and mortality, and it is associated with chronic diseases, including cardiovascular disease and diabetes. Based on the findings, it is essential to modify heath behaviors for preventing abdominal obesity, which is a condition associated with the incidence of chronic disease.

This study was conducted to comprehensively identify factors that potentially influence corporate investment behavior, including micro, macro, and sectoral variables. Furthermore, investment behavior was studied across nations based on their participation in the global value chain (GVC), which was evaluated based on commodities, limited manufacturing, advanced manufacturing, and innovative activities. The study uses the dynamic panel data analysis and Generalized Method of Moment (GMM) estimation for a sample of 800 corporations, with data spanning over 2000-2019. The study result shows that in all types of countries, the coefficient lag indicator of capital expenditure statistically has a significant effect on capital expenditure. Sales growth, exchange rate, and GDP have a significant positive effect on corporate investment growth, while DER has a negative effect. In commodity countries, corporate investment is influenced by sales growth, exchange rate, and FCI. The variables that influence corporate investment in manufacturing countries are the FCI, exchange rate, sales growth, GDP, and DER. In innovative countries, variables that significantly affect capital expenditure are DER, GDP, and Tobin Q. In each type of country, the interaction terms between exchange rate and commodity price are positive and statistically significant.
