This study examined Korean employees' meal structure characterized by mealtime, meal places, and companions. The data from 19,692 time diaries, recorded by 9,846 employees aged 19-64 years for two days in the 2014 Korean Time Use Survey, were analyzed for working days and non-working days. Approximately two-thirds of Korean employees ate meals three times a day on both working and non-working days. The breakfast and lunch-times on working days were distributed within two hours, but the dinner time on working days and all three meals on non-working days were dispersed across a three-hour range. Male employees spent three minutes on meal preparation on working days, whereas females spent 30 minutes. On working days, 88% of breakfasts and 67% of dinners were eaten at home. For lunches, 46% were eaten at restaurants, and 42% were at workplaces. The breakfast on working days showed the highest percentage of eating alone (40%) and the dinner on non-working days appeared highest in the percentage of eating with families (69%). The characteristics of Korean employees' meal structure appeared different on working days and non-working days. Such characteristics should be considered in the process of planning nutrition policies and programs for employees.

Augmenting the Wide Field Infrared Survey Telescope (WFIRST) microlensing campaigns with intensive observations from a ground-based network of wide-field survey telescopes would have several major advantages. First, it would enable full two-dimensional (2-D) vector microlens parallax measurements for a substantial fraction of low-mass lenses as well as planetary and binary events that show caustic crossing features. For a significant fraction of the free-floating planet (FFP) events and all caustic-crossing planetary/binary events, these 2-D parallax measurements directly lead to complete solutions (mass, distance, transverse velocity) of the lens object (or lens system). For even more events, the complementary ground-based observations will yield 1-D parallax measurements. Together with the 1-D parallaxes from WFIRST alone, they can probe the entire mass range M ≳ M_⊕. For luminous lenses, such 1-D parallax measurements can be promoted to complete solutions (mass, distance, transverse velocity) by high-resolution imaging. This would provide crucial information not only about the hosts of planets and other lenses, but also enable a much more precise Galactic model. Other benefits of such a survey include improved understanding of binaries (particularly with low mass primaries), and sensitivity to distant ice-giant and gas-giant companions of WFIRST lenses that cannot be detected by WFIRST itself due to its restricted observing windows. Existing ground-based microlensing surveys can be employed if WFIRST is pointed at lower-extinction fields than is currently envisaged. This would come at some cost to the event rate. Therefore the benefits of improved characterization of lenses must be weighed against these costs.

The purpose of this study was analyze how korean adult women\`s swimming suit buying behavior varied according to consumer characteristics. Especially, it was intended to provide basic materials for swimming suit product development and quality improvement appropriate to consumer characteristics with a focus on product evaluation criteria. Questionnaire research was conducted for 850 adult women resident in Seoul, to whom questionnaire were distributed and who were asked to complete their questionnaires. 1. As for buying motive, of swimming suit buying behavior, it was shown that the highest proportion of adult women bought their new swimming suit because their old swimming suit was wornout and most adult women tended to buy their new swimming suit or their own will rather than at others\` suggestion. 2. As for the source of information at a time. of swimming suit purchase, adult women collected information from the product on display most and bought their swimming suit in a planned way in relation to the degree of purchase planning. 3. As for product evaluation criteria, adult women showed the high scores in order of the type and quality of material, activity and functionalism, dimensions and fitness. 4. In many cases actual swimming suit purchasers were the adult women who bought their swimming suit, and they used the department store or the large shopping center as the place of purchasing the swimming suit. Its reason was that the department store or the large shopping center had a diverse assortment of products. As for the degree of their travelling companion\`s influence, it was found that most adult women were influenced by their travelling companions when purchasing their swimming suits. 5. As for the level of satisfaction with swimming suit purchase, it was shown that adult women were generally satisfied with their swimming suit purchase. It was found that their level of satisfaction was higher in order of activity and functionalism, the type and quality of swimming suit materials, and ease in washing management while they showed the low level of satisfaction with price, the fastness of color to washing, light and detergents and durability.

We investigated the prevalence of canine brucellosis in companion and stray dogs between March 2015 and December 2016 and determined the disease characteristics based on the geographic distribution, sex and age of the dogs in South Korea. We conducted a large-scale survey using serological and bacteriological tests. Samples were collected from 2,394 dogs (1,825 companions and 569 strays). Thirty (1.3%) samples were positive for Brucella canis antibodies including 16 (0.9%) from companion dogs and 14 (2.5%) from stray dogs. Two (1.0%) of the 196 samples cultured from the stray dogs were positive. When compared with male dogs, the female companion and stray dogs had a significantly higher prevalence of brucellosis. Moreover, the prevalence of canine brucellosis was significantly higher in stray dogs older than 6 years and the prevalence of the disease in companion dogs was highest in Incheon (2.1%) and Jeolla (2.1%) provinces. Stray dogs from the Daejeon metropolitan area had the highest prevalence of brucellosis (7.9%). National control measures for canine brucellosis have not previously been implemented. Our findings suggest that appropriate screening tests and control measures are necessary to improve the health of dogs and to protect public health in Korea, particularly with the rapid growth of the companion animal industry.

The mass measurement of neutron stars or black holes is of fundamental importance in our understanding of the evolution of massive stars and core-collapse supernova explosions as well as some exotic physics of the extreme conditions. Despite the importance, however, it's very difficult to measure mass of these objects directly. One way to do this, if they are in binary systems, to measure their binary motions (i.e., Doppler shifts) which can give us direct information on their mass. Recently many new highly-obscured massive X-ray binaries have been discovered by new hard X-ray satellites such as INTEGRAL and NuSTAR. The new highly-obscured massive X-ray binaries are faint in the optical, but bright in the infrared with many emission lines. Based on the near-infrared spectroscopy, one can first understand the nature of stellar companions to the compact objects, determining its spectral types and luminosity classes as well as mass losses and conditions of (potential) circumstellar material. Next, spectroscopic monitoring of these objects can be used to estimate the mass of compact objects via measuring the Doppler shifts of the lines. For the former, broad-band spectroscopy is essential; for the latter, high-resolution spectroscopy is critical. Therefore, IGRINS appears to be an ideal instrument to study them. An IGRINS survey of these new highly-obscured massive X-ray binaries can give us a rare opportunity to carry out population analyses for understanding the evolution of massive binary systems and formation of compact objects and their mass ranges. In this talk, we will present a sample near-infrared high resolution spectra of HMXB, IGR J19140+0951 and discuss about its spectral feature. These spectra are obtained on 13th July, 2014 from IGRINS commissioning run at McDonald 2.7m telescope. And at final, we will introduce the upgrade plan of IGRINS Operation Software (IGOS), to gather the input from IGRINS observer.

The recent increase in the number of dogs in high-density urban environments causes conflicts between dog owners and non-dog owners and the access of dogs to urban parks has been controversial among park users. A lack of exercise and socialization, however, can cause canine behavior problems such as aggression and hyperactivity which are potential dangers to people and there has increased demand for a place where people and their dogs can interact and exercise together. In many developed countries, off-leash recreation areas (OLRA) are considered as safe and effective places that dogs can exercise, play, and socialize with other dogs while reducing conflicts between dog owners and other park users. This study aimed to review the issue of dogs' access to public parks and to examine the perception of park users on OLRA to provide insights and guidelines in establishing OLRA in Korea. The survey respondents, even non-dog owners, perceived that it is necessary to provide a separate space for dogs from other park users by providing OLRAs in urban parks and showed the willingness to use. Most of dog owners consider their dogs as companions or family members and feel the lack of places to exercise their dogs. As local government plays a major role in urban animal management which emerge as a social issue at present, more active interventions of municipalities are necessary to support various needs and activities of park users. An experimental OLRAs based on community participations would be a meaningful starting point to effective urban animal management.
