With the renewed definition of "office". it's function and role has been reduced. Therefore. home oofices are beginning to draw people's attention. Office within the home is called SOHO (Small Office Home Office). SOHO has become possible with the development of information and telecommunication network technology. Recently. companies are adopting the SOHO system along with the trends of business restructuring. The SOHO offers workers to enjoy more flexible work time and enhance concentration thus improving jop efficiency. Companies will be able to cut down on fixed expenses and increase productivity. In addition. such working conditions will contribute to relieve traffic and environmental problems and furthermore it will make it possible to take advantage of potential workforce of women. the elderly and the handicapped. "Home Office" is expected to be one of the prevailing work system in the near future. Therefore. it is all the more important to study design problems including space design and furniture arrangement in order to improve work efficiency and provide a creative working environment. Moreover. architects and interior designers as well as experts on related fields such as information network. telecommunications. management and employment should continue to carry out joint researches for reasonable home office furniture and environment design.nd environment design.

Translational research (TR) as high quality research can accelerate collaboration strongly between biotechnology-based researchers and clinical-research experts for overcoming diseases. TR facilitates basic science translated to clinical efficacy and effectiveness from bench (basic science) to bedside (clinical practice) for the enhancement of human health. Disease-oriented TR programs were defined as unilateral, bilateral and multilateral TR in this patent performance analysis. Patent performance was measured in a R&D project on Health and Medical Technology to enhance the productivity of R&D investment on disease-oriented TR in Health Technology (HT). Patent Map (PM) analysis and Bibliometrics were conducted to collect information for the assessment of research patents of TR programs. Futhermore, PIAS (Patent Information Analysis System) and Thinklear programs were applied for quantitative and qualitative analysis successfully. These indicate that multi-dimensional analysis of patent performance for disease-oriented TR could promote the connection of R&D-IP (Research and Development-Intellectural Property) and R&BD (Research and Business Development) supporting system significantly.

Korea has the tenth largest film industry in the world; however, detailed analyses using the factors contributing to successful film commercialization have not been approached. Using big data, this paper analyzed both internal and external factors (including genre, release date, rating, and number of screenings) that contributed to the commercial success of Korea's top 10 ranking films in 2011-2015. The authors developed a WebCrawler to collect text data about each movie, implemented a Hadoop system for data storage, and classified the data using Map Reduce method. The results showed that the characteristic of "release date," followed closely by "rating" and "genre" were the most influential factors of success in the Korean film industry. The analysis in this study is considered groundwork for the development of software that can predict box-office performance.

A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the determination of caffeine in forensic aqueous sample. The centrifuged sample ($100{\mu}l$) was diluted 50-fold with distilled water. The diluted sample ($400{\mu}l$) was then diluted further with $200{\mu}l$ of 0.1% formic acid solution and $400{\mu}l$ of acetonitrile containing 500 ng of caffeine-(3-methyl-$^{13}C_3$) prior to LC-MS/MS analysis. The mobile phase was composed of 0.1% formic acid in distilled water (A) and acetonitrile (B). Chromatographic separation was performed by using a Zorbax SB-C18 ($100mm{\times}2.1mm$ i.d., $3.5{\mu}m$) column and caffeine was eluted within 1.1 min. Linear least-squares regression with a 1/x weighting factor was used to generate a calibration curve with the coefficients of determination ($r^2=0.9983$). The lower limit of quantification was $25ng/ml$ for the analyte. The process efficiency was 98.6~100.1%. Intra- and inter-day precisions were not more than 2.1% and 1.7%, while intra- and inter-day accuracies were ranged from -6.8 to 4.5%, respectively. The suitability of the method was examined by analyzing unknown forensic aqueous samples.

The Office of Science and Technology Innovation (OSTI) was created by a different method of organizational change from that of precedent administrative reforms. According to results of the new method, the OSTI case can be widely applied to other ministries as an alternative model for governmental reform. The theory part introduced two approaches of organizational reform, namely structural approach which focuses on the level of hierarchial authority and process approach which emphasizes the flow of information/expertise in organizational operation. It also discussed various ways of understanding for S&T policy coordination. After this, the paper reviewed details of the OSTI reform with special reference to implications for the mode of S&T policy coordination. It concludes that the OSTI may offer an opportunity to strengthen the coordination mechanism of the process approach.

Background: This study investigated the relationship between depressive symptoms and physical fitness, obesity indices, and vitamin D status in office workers. Methods: The subjects were 514 adults with more 30 years of experience as office workers in the city of Seoul. Lifestyle risk factors, obesity indices, physical fitness, and serum vitamin D levels were assessed with a standardized protocol. The Beck Depression Inventory (BDI) was used to assess depression status. Vitamin D status was assessed by measuring serum 25-hydroxyvitamin D concentrations. Based on the BDI scores, participants were classified into no depression (ND, $BDI{\leq}9$), mild depression (MiD, $10{\leq}BDI{\leq}15$), and moderate depression (MoD, $16{\leq}BDI{\leq}23$) groups. Results: Compared with the high cardiorespriatory fitness group, the low cardiorespiratory fitness (men OR=2.618, women OR=1.596) an middle cardiorespiratory fitness group (men OR=1.256, women OR=1.110) had significantly higher odds ratio for having depressive symptoms, even after adjustment for age, hypertension, diabetes, hyperlipidemia, cardiovascular disease, alcohol intake, smoking, body mass index (BMI), percent body fat (%BF), and waist circumference (WC). Compared with the insufficient or deficient vitamin D group , the sufficient vitamin D group had significantly lower odds ratios for having depressive symptoms (men OR=0.121, women OR=0.114), even after adjustment for age, hypertension, diabetes, hyperlipidemia, cardiovascular disease, alcohol intake, smoking, BMI, %BF, and WC. Conclusion: Vitamin D supplementation and outdoor activities should be key components of a lifestyle intervention against office workers' depression.

The outbreak of apple scab was found on the apple seedlings growing in Korea which were imported from Marylang, U.S.A. in 1972. Symptom of apple scab is much similar with pear scab caused by Venturia pirina except that the round spot on leaves, more lesions on upper side of leaves and much severe symptoms appeared on both side of leaves. About $14\%\; and \;12\%$ of plants were infected in 1972 and 1973, respectively.

This study was conducted to establish the research direction of heat stress in dairy cows by searching papers and patents. Research papers published before 2014 through National Digital Science Library (NDSL) and patents registered with United States Patent and Trademark Office (USPTO), Japan Patent Office (JPO), European Patent Office (EPO) and Korean Intellectual Property Office (KIPO) were investigated using the key words of heat stress index, genetics, facilities and feed. The research trend for heat stress in dairy cows was analyzed with 182 papers and 282 patents. Global warming due to increased atmospheric concentration of greenhouse gases is a major interest in recent years. The papers related with heat stress in cattle were increased after 2006. Besides, patents connected with facilities and feed will be increased due to development of ICT. In particular, the various studies including patents about heat stress in dairy cows will be needed to conduct because the climate of southern Korean peninsula is changing from temperate to subtropic.
