Using the data from 1980 to 2017, I show the long-term trends in the gender wage gap in Korea and analyze factors using decomposition method. It tended to decline until the 1990s, but gradually slowed after the 2000s. Gelbach(2016)'s decomposition method is used as an alternative rather than Blinder-Oaxaca decomposition. The results show that the proportion of explanation of traditional factors, such as age, education, firm size, industry and occupation, are continuously decreasing in explaining the gender wage gap. Expecially, the proportion of explanation of age and that of education have decreased, and that of industry tended to decrease in the 1990s but to increase after the 2000s.

매일 7,000명의 젊은이들이 HIV에 감염된다. 우리나라에서도 10대 감염자가 20여명에 이르는 것으로 알고 있다. 앞으로도 젊은이 비중이 늘어날 것으로 보여 젊은이들의 역할의 중요성이 늘어나고 있다.

In general, specific gravity (SG) and urinary creatinine (CR) have been used to adjust urinary cadmium (Cd) concentrations. However, the validity of correction methods has been controversial. We compared the two adjustments to evaluate associations between urinary Cd and various renal damage markers and to evaluate the relationship between urinary Cd concentration and renal disease markers, such as estimated glomerular filtration rate (eGFR), in a relatively large general population sample. Among the 1,086 volunteers who were enrolled in this study, 862 healthy volunteers who did not have kidney disease were included in the final analysis. Urinary Cd, malondialdehyde (MDA), and N-acetyl-${\beta}$-D-glucosaminidase (NAG) concentrations were measured, the creatinine-based eGFR was calculated, and the relationships between these markers were subsequently analyzed. This study showed the use of urinary Cd concentration adjusted with SG rather than with urinary creatinine may be appropriate in studies evaluating renal function based on Cd exposure. Urinary Cd concentration adjusted with SG had a positive correlation with urinary MDA levels and a negative correlation with eGFR. This relationship was relatively stronger in women than in men. This study showed that urinary Cd level was associated with decreased eGFR in the general population, and oxidative stress was likely to act as an intermediator in this process. These results suggest that eGFR can be a very good indicator of kidney damage caused by Cd exposure in the general population.

The purposes of this study were to 1) develop fluid intake enhancing program for the institutionalized elderly and 2) examine the effect of fluid intake enhancing program on amount of daily fluid consumed, urine specific gravity, and urine color. Data were collected from 39 nursing home residents in a nursing home located in urban Chung-chung providence. With a convenient sample of 39 nursing home residents, consecutive three days of 24 hour fluid intake, were measured and recorded. Urine samples were obtained and urine specific gravity, urine color were analyzed at pre-intervention, 4 weeks, and 6 weeks following the intervention. When compared to pre-intervention, the average amount of daily fluid intake was significantly increased at 4 weeks and 6 weeks following the intervention. The proportion of subjects who consumed less than Adequate Intake(AI) was 35.9% at pre-intervention and was decreased to 10.3%, 7.7%. In conclusion, inadequate fluid intake among institutionalized elderly is prevalent. From careful employment of the fluid intake enhancing program, increase in fluid consumption among institutionalized elderly can be expected.

The urinalysis is an essential part of the diagnostic work-up for kidney disease and other renal system disorders. The dipstick test allows rapid and simultaneous chemical analyses of urine, including factors such as pH, specific gravity, protein, glucose, ketones, occult blood, bilirubin, urobilinogen, nitrite, and leukocyte-esterase. The chemical reactions on dipstick are complicated and can be affected by oxidizing, reducing, and discoloring substances in the urine. Therefore, false positive and false negative results are common in dipstick testing. To obtain reliable results with the dipstick, it is necessary to collect urine cleanly and examine the urine carefully. It is mandatory to clearly understand the principles of dipstick testing to evaluate abnormal findings. If the urine dipstick results suggest hematuria, proteinuria, or urinary tract infection, microscopy of the urine should be performed to confirm the findings.

COVI-19 이후 콜드체인 시스템의 중요성이 증가함과 함께 냉동물류센터에 대한 중요성도 부각되고 있다. 향후 냉동물류센터의 양적·질적 팽창은 불가피하며 그에 따른 위치선정의 중요성도 커지고 있다. 하지만, 대다수의 국내 냉동물류센터는 단순보관의 역할 위주에, 도심이나 주요도로와 멀리 떨어져 있고, 노후화의 문제를 가지고 있다. 또한 냉동물류센터는 에너지 소비가 많은 만큼 위치선정에 따른 비용문제도 큰 영향을 미친다. 따라서 본 연구는 AHP를 활용하여 부산 경남 냉동 물류 센터의 위치 경쟁력 결정 요인을 분석하고자 한다. 시설요인, 서비스 요인, 위치 요인, 그리고 비용 요인의 네 가지 영역과 이를 세부적으로 나누어 19개의 항목을 계층화하여 상대적 중요도를 평가하였다. 연구결과는 냉동물류센터의 입지결정요인과 기존에 냉동물류센터에 요구되던 기본적인 요소에 입지경쟁력 분석을 위한 우선 순위를 계층화하였다. 비용요인이 국내 냉동물류센터 입지경쟁력의 결정요인 중 가장 높은 비중을 차지하였다. 실제 시설인프라와 물류연결성은 관련 업종 근무자들이 가장 민감하게 받아들이는 사항이기도 하며 새로운 냉동물류센터의 도입 시에도 필수적으로 참고가 되어야할 것으로 보인다. 본 연구는 냉동물류센터 종사자 및 관련업계 종사자들이 어떠한 요인을 냉동물류센터의 입지경쟁력 결정요인으로 비중 있게 고려하고 있는지를 도출하였고, 향후 입지경쟁력 향상을 위한 전략적 시사점을 제공한다.

The urban representative landscapes play a leading role in establishing city identity via a symbol of the city and a mediator to make the city all the more worthy of being peculiarized. The study aims at evaluating the perceptive factors in the representative landscapes around the metropolitan Seoul derived from the preliminary researches through questionnaire surveying, in an attempt to analyze their characteristics by type and reason, while further proposing progressive management plans. This study was mostly focused on the visibility factor, activity factor, aesthetic factor and cultural factor influencing on the cognition of urban representative landscapes. The important findings discovered in this research are as follows. First, it was found that people were being interested more on the cultural factors and the activity factors these days rather than visibility factors in the cognition of urban representative landscapes. Second, it was found that the priority rank of urban representative landscapes revealed in this study based on the total account of more diverse perceptive factors, showed so much alteration compared to the previous researches focused mostly upon the visual image.

Using survey data and the Heckit model that adequately controls the sample selection bias, we analyze shoppers expenditure through two major emerging shopping channels: Internet shopping and TV home shopping channels. Age, Internet experience, daily Internet usage, the number of computers are factors that affect the ratio of consumers' expenditure through Internet shopping relative to the expenditure through TV home shopping. Shopping frequency which represents the shoppers' incentives to reduce transaction costs also has a positive effect on the proportion of shoppers' expenditure through the Internet shopping. Shoppers' perceptions of convenience, reliability, speed, and diversity are also shown to affect shoppers' relative expenditure ratio through Internet shopping. In contrast, shoppers' perception of prices does not seem to affect their purchasing behavior.

India has been service-led economic growth during 50 years and turned to the so-called 'service economy' which means that the services sector takes over 50% in GDP since 2000 year. This study aims to find the factors in the existing hypotheses for service economy in India and tries the empirical analysis with the 1953~2003 annual time series data. As a result, the service economy in India has been accelerated by the hypotheses of demand bias, productivity bias and demand increasing of services as the intermediates simultaneously. This implies that the phenomenon of service economy will be continued and furthered in India.
