목적: 신축건물 재실자들의 안구건조증을 조사하고, 안구건조증이 작업생산성 및 일상적인 활동에 미치는 영향에 대해 알아보았다. 방법: 신축한지 3개월이 지난 건물에서 일 평균 8시간 이상을 근무하는 사무직 근로자 33명을 대상으로 하였다. 실내공기질은 알데하이드류와 온습도를 측정하여 평가하였다. 안구건조증은 Ocular Surface Disease Index(OSDI)를 이용하여 정상, 경도, 중등도 및 중증으로 분류하였고, 라식수술, 눈 화장, 일일 컴퓨터와 스마트폰 사용시간, 그리고 일일 평균 근무시간을 조사하였다. 작업생산성과 일상활동 관련 설문은 Work Limitation Productivity 설문을 사용하여 손실정도를 10점 척도로 체크하였다. 결과: 사무실의 폼알데하이드 농도는 $42.42{\pm}6.30{\mu}g/m^3$ 이었고, 온습도는 각각 $26.2{\pm}0.7^{\circ}C$와 $40{\pm}1%$ 였다. 안구건조증은 정상, 경도, 중등도 및 중증이 각각 15.2%, 18.2%, 18.2%, 48.5%였다. 안구건조증의 심한 정도와 작업생산성 및 일상적인 활동의 손실 정도는 각각 0.599와 0.655의 높은 상관성을 보였다(p<0.001). 안구건조증이 중증인 경우는 정상에 비해 유의하게 높은 작업생산성 손실과 일상활동 저해를 나타냈다(p<0.001). 안구건조증이 심한 경우는 정상에 비해 작업생산성 손실과 일상활동 저해가 3점 이상일 확률이 각각 3.26배(p=0.032)와 2.25배(p=0.045) 높았다. 결론: 신축건물 사무직 근로자들의 안구건조증은 작업생산성과 일상적인 활동에 영향을 미치는 것을 확인할 수 있었다.

The paper presents the results of a study on the determinants of customer satisfaction for a retail bank using the data of 2009 NCSI(National Customer Satisfaction Index, KPC). In doing so, it uses a revised version of the traditional analyses based on derived measures of attribute importance. The need for a revised methodology is prompted by the insights of the two- and three-factor theories of customer satisfaction, such as Kano's framework. Indeed, the evidence from 1635 customers of 6 Korean banks confirms an asymmetric relationship between attribute performances and overall customer satisfaction. The results from both a traditional and our revised approach are compared. While this approach can be applied across different industries, it should not be assumed that the numerical results presented in the paper apply to contexts with substantially different underlying characteristics. General trends and practical implications for banking services are reported in the conclusions.

This paper selects length of berth, area of yard, unloading capacity and number of berth as the input indexes, and cargo turnover as output index to research the source of TFP(Total Factor Productivity) growth of 23 main ports in Korea. The major conclusions are as follows. The TFP of the trade ports in Korea is at the fluctuating stage, but it generally displays a rising trend, and it’s growth originate from the growth of technical efficiency. The Growth rates of TFP of trade ports in the different areas are different, and the sources of growth are also different, but the changing trends are basically the same. Four major factors to the increase of TFP are following: competition between ports, reform of property system, harbor-hinterland economic and international trade, modeling, imitation and innovation in management, technology and system.

This study aims to estimate the production function and total factor productivity (TFP) of Vietnamese seafood processing firms. At the same time, the study analyses the impact of internal factors of firms and the quality of economic institutions on the TFP of the Vietnamese seafood processing industry. The study uses the Function Control (FC) approach in TFP estimation and the Feasible Generalized Least Squares (FGLS) regression model in the analysis of factors affecting TFP. The study was carried out on the census data of enterprises of the Vietnamese seafood processing industry collected by the Vietnamese General Statistics Office and Provincial Competitiveness Index data of Vietnam Chamber of Commerce and Industry in the period from 2013 to 2018. Estimated results from the models show that: i) Vietnamese seafood processing firms are, currently, mainly labor-intensive, the TFP contribution and output is only about 2.258. ii) Factors such as the firm's age, firm's size, and the firm's ownership affect TFP. In which, firms that have few numbers of years of operation, small and medium firms, and private firms have low TFP. iii) Institutional quality and the provincial business environment have a positive impact on the TFP of Vietnamese seafood processing firms in this period.

본 연구는 동계사료작물의 무인기기반 생육모니터링을 위하여 호밀, 총체보리, IRG를 대상으로 다중분광영상으로 건물수량을 예측하기 위한 최적식생지수를 테스트하였다. 2019년 2월부터 4월까지 나주의 실경작지에서 무인기 다중분광카메라로 분광영상을 수집하여 4종류의 식생지수(Normalized Difference Vegetation Index; NDVI, Green Normalized Difference Vegetation Index; GNDVI, Normalized Green Red Difference Index; NGRDI and Normalized Difference Red Edge Index; NDREI)를 산출하고 지상에서 건물수량을 조사하여 식생지수와 건물수량의 상관관계를 조사하였다. 호밀, 총체보리, IRG에 대하여 건물수량과 NDVI의 상관관계(R2)는 0.91~0.92, GNDVI는 0.92~0.94, NGRDI는 0.71~0.85, NDREI는 0.84~0.91로 GNDVI가 가장 효과적이었다.

This study identified vulnerable regions in the national parks of the Republic of Korea (ROK). The potential vulnerable regions were defined as areas showing a decline in forest productivity, low resilience, and high sensitivity to climate variations. Those regions were analyzed with a regression model and trend analysis using the Enhanced Vegetation Index (EVI) data obtained from long-term observed Moderate Resolution Imaging Spectroradiometer (MODIS) and gridded meteorological data. Results showed the area with the highest vulnerability was Naejangsan National Park in the southern part of ROK where 32.5% ($26.0km^2$) of the total area was vulnerable. This result will be useful information for future conservation planning of forest ecosystem in ROK under environmental changes, especially climate change.

Food procurement practices were assessed in 31 general hospital's dietetics in terms of the level of processing for purchased food. The level of processing before purchase by the institution was noted by a numerical value. a Food Processing Index (FPI). Labor productivity measured in terms of labor minutes per meal served averaged 12.59 minutes. Responsible persons for procurement practices were mostly dietitians, but effective purchasing methods as well as inventory control techniques were not fully systematized. Dietetic directors anticipate the large increase in the use of convenience foods in the future mainly due to the improved labor productivity, and also a highly increasing demand for completely pre-prepared food items (FPI 3). The grand mean of FPI scores for purchased foods in surveyed hospitals was 3.34, which indicates partially pre-prepared to completely pre-prepared food items. Significant negative correlation was found between the grand mean of FPI scores and the number of beds in a hospital.

This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to spring framework 2.5. Non EJB and the EJB architecture to resolve the problem with benefits to support the new architecture is a lightweight container architecture. This architecture, such as the EJB, but not heavy, to provide all of the architecture is possible. The lightweight container architecture is most often used in business spring framework is well-known architecture. Therefore, this research has the Non EJB and the EJB to solve the advantages and disadvantages developed to support the latest spring framework 2.5 lightweight container architecture based on the design and implementation of a pilot system with the objective through the specification of the software previously to provide guidance to development productivity.
