The objective of this study is to establish a standard size for clothing construction and to develop a basic bodice pattern for Misses. 1. Seven kinds of pattern generally used in Korea were collected and compared in the aspect of items of necessary measurements and application of measurements to pattern drawing. 2. 209 girls aged 17 to 25 were measured on 22 items. The measurements were analyzed by calculation of means, standard deviations, co-variance, range, maximum, minimum, and correlation co-efficient between each item. the data were classified into four size groups according to bust size. Correlation co-efficient between each item were as follows: 1) Correlation co-efficients of bust to upper bust and waist were very high. 2) Correlation co-efficients of bust to shoulder width, across back and across chest were relatively high (r=.6385, r=.7493, r=.6344, respectively). 3) Bust had little correlation to neck and shoulder slope.

To determine the movement patterns, home range, and use of structural features of captive-bred one- or two-year-old Amur ratsnake (Elaphe schrenckii) juveniles in the natural habitat, we radio-tracked a total of 11 juvenile snakes in a mountain valley in Chiaksan National Park, South Korea, between August 21 and September 20, 2010 and between June 13 and July 13, 2011. During the first week of the release, most juveniles moved short distances, daily, but they increased their distances after the first week. The body weight of the juveniles was negatively related with the movement rate (dividing the number of movements by the number of relocations), which was positively related with the mean daily distances moved and the size of both a kernel 50% and 95% home range. During the study period, the juveniles moved daily, approximately 17 m, and the size of the minimum convex polygon and the 50% and 95% kernel home ranges were 1.8 ha, 0.4 ha, and 3.0 ha, respectively. The released captive-bred juveniles were more frequently confirmed underground or on the ground rather than on rocks or on trees. Our results suggest that the body condition of released individuals, the seasonal time of the release, and the existence of available prey and shelters in the habitat should be carefully considered when releasing captive-bred Amur ratsnake juveniles for the rehabilitation of field populations.

The primary aim of this study is to estimate the home range of a pair of raccoon dogs(Nyctereutes procyonoides koreensis) and to compare with the previous study of raccoon dogs in a rural area of Gurye, the southern part of South Korea. Radiotracking was regularly carried out on 2 raccoon dogs for 2 days every 2 months(in June, August, October and December, 2006). During the 2 days, radiotracking was usually conducted every $1{\sim}3$ hours through day and night. The analysis of tracking data with a total of $46{\sim}64$ bearings showed that the total home range size of the pair was $0.41km^2$, and mean home range size was $0.32km^2$ by 95% minimum convex polygons(MCP) estimate. The home ranges of the male and female were largely overlapping(about $70{\sim}95%$), and the sizes were not very much different from each other. However, there was a big difference between day $(0.01km^2)$ and night-time $(0.35km^2)$ home ranges, and it was largest in summer$(0.56km^2)$ and smallest in winter $(<0.01km^2)$. In addition, the home range of the pair included 1 core area and 4 different feeding areas. In conclusion, our raccoon dog home range data using the same individuals but with more frequent bearings per day and more extended tracking intervals still showed very similar results to the previous study with less frequent bearings per day and more extensive tracking days.

Two different methods (Sieve shaker, Elzone particle size analyzer) were used to investigate rice flour particle size obtained by various milling method. Results of Elzone particle size analyzer were more effective than Sieve shaker in determining particle size, and the distribution of particle size of rice flours was affected by the type of the milling methods used. A rice flour, prepared in a Pin mill had a particle size range of $60{\sim}500$ mesh, and 30.38% of the sample was in the particle size range $200{\sim}270$ mesh. A rice flour, prepared in a Colloid mill had a particle size range of $40{\sim}500$ mesh and more of flour particles appeared in the range $140{\sim}200$ mesh than any other particle size. A rice flour, prepared in a Micro mill had a particle size range of $140{\sim}500$ mesh, and 41.62% of the sample was in the particle size range over 500 mesh. A rife flour, prepared in a Jet mill had a finer flour particle size was over the particle size range 500 mesh. The finer rice flour gave the highest L value and the lowest a value. The wet-milled flour particles were observed as a cluster of starch granules and the particles of rice flour (dry-milling) were observed as fragment of rice grains. Scanning Electron Photomicrographs revealed that visual differences in structure between milling methods, and similar results with Elzone particle size analyzer method in particle size.

This study was to carry out interview and survey of currently marketed foundation garment, focusing on manufacturers, on the basis of data of Year 2004 SIZE KOREA in 2004, to re-establish suitable age range and standard size, to simplify size interval scale and size system and to revise the standard for consumers' easy understanding and availability; The findings of this study are as follows. 1. Considering the age, in which a bra is worn, has reduced socially, the applicable age range was expanded into $8{\sim}80$ years old, which was divided into for junior and for adult. 2. For bra size, the standard title changed into the foundation garments size standard, in which girdle and bodysuit were included. 3. Basic physical parts for establishing for bra size are underbust and bust. Interval scale of under bust and bust was 5cm and 2.5cm, respectively. And basic physical parts are waist and hip girth for girdle, and underbust, bust, and hip girth for bodysuit. 4. For bra size, underbust girth was applied together with bra-cup size without 'cm' unit. For bra-cup size, difference between underbust and bust was represented as English alphabet. In other words, AAA means that difference between under bust and bust is 5cm. AA, A, B, C and D means that the difference are 7.5cm, 10cm, 12.5cm, 15cm and 17.5cm. 5. For girdle size, waist girth was applied together with hip girth without 'cm' unit. And for bodysuit size, underbust girth was applied together with cup size like bra size, and English alphabet represented hip girth range.

A project has recently begun to reintroduce endangered Asiatic black bears to the Jirisan National Park. However, information on home range that is necessary to maintain the Minimum Viable Population (MVP) of those bears does not exist. Based on point data of two bears that were released for trial in Jirisan in 2001, we identified the movement pattern of bears and estimated their home ranges with two different methods Finally, the possibility of conserving the MVP of bears was evaluated by comparing the location and size of the home range with habitats which have been found to be suitable for bears. The frequency of bears' appearance reduced drastically as road densities of both paved roads and legal trails increased. The midpoint of home ranges of the two bears was 376.85 $km^2$ and 50.76 $km^2$ based on 100% MCP (Minimum Convex Polygon) and 95% AK (Adaptive Kernel Home Range Method), respectively, with an overlapped area of 126.0 $km^2$ and 3.99 $km^2$ each. The core areas of their home ranges are located not in the no-entry zone, where major trails were open to the public - despite being designated as no -entry zone - but in areas where most trails were closed to the public. A discrepancy between core areas of home ranges and potentially suitable habitats suggests the effects of vehicles and tracking people through roads within the park. Thus, for the success of in situ conservation of endangered bears, well-planned management of habitats is needed to protect bears and to ensure the home ranges to support the MVP.

In this paper, we propose a Designed and Developed home router management system. Through the fourth industrial revolution and development of IoT technology, now people can experience a wide range of IoT related services at their workplace or daily lives. At the industrial site, IoT devices are used to improve productivity such as factory automation, and at home, IoT technology is used to control home appliances from a remote distance. Usually IoT device is integrated and controlled by the router. Home router connects different IoT devices together at home, however when security issues arise, it can invade personal privacy. Even though these threats exist, the perception for home router security is still insufficient. In this paper, we have designed and developed home router management system using DEVS methodology to promote the safe use of home router. Through the DEVS methodology, we have designed the system and developed the mobile application. This management system enables users to set up security options for home router easily.

Migratory birds use a variety of breeding and wintering sites, and it is particularly important to understand more information on breeding and feeding sites for the conservation and management of endangered species. Black-faced spoonbills (Platalea minor) are an international endangered species distributed in East Asia. The majority of black-faced spoonbills breed on uninhabited islets off the west coast of the Korean Peninsula during the breeding season, and they are distributed in East Asia such as Taiwan, Hong Kong, southern China, Japan, and Jeju island during the winter season. In this study, we used a wild animal location tracking system to analyze and compare home ranges of three black-faced spoonbills spending the post-fledging stage in Gujido islet in Incheon and Chilsando islet in Yeonggwang each in 2015. The tree black-faced spoonbills in Guji islet showed a home range in coastal areas in Hwanghaenam-do and Gangneung-gun. The home range size (mean±SD) was estimated to be 425.49±116.95 ㎢ using 100% MCP, 43.61±18.51 ㎢ using KDE 95%, and 7.46±3.68 ㎢using KDE 50%. The tree black-faced spoonbills in Chilsando islet showed a home range in the Baeksu tidal flat and the Buan Saemangeum area with a size of 99.38±55.29 ㎢ using 100% MCP, 19.87±6.05 ㎢ using KDE 95%, and 1.16±0.53 ㎢ using KDE 50%. The figured indicated that the tree black-faced spoonbills breeding in Gujido islet had a wider home range than those breeding in Chilsando islet. During the post-fledging stage, the home ranges of black-faced spoonbills were mostly breeding in mudflats. Therefore, it is necessary to minimize human intervention, such as the construction of roads and structures and the human access, to protect the habitats during the period.

This study was conducted to analyze the actual wearing conditions and body fit preferences of the middle-aged women's ready-to-wear lower body clothing. The aim was also to analyze lower body recognition, lower body satisfaction, fit preferences and size satisfaction according to age and degree of girth size. A questionnaire was developed and administered to 300 middle-aged women aged 34 to 59. Statistical tests such as descriptive analysis, crosstabs, and X²-tests were conducted to analyze the data and ascertain the differences between the ages. Lower body satisfaction and recognition were compared by T-test. Also, Anova was used to analyze lower body recognition, satisfaction, fit preferences, and size satisfaction according to age and degrees of girth size. The results indicated that women aged 50 to 59 were more dissatisfied with the ready-to-wear sizing system and because of their body shapes had changed, their need for a larger size range system had also increased. Moreover, the element that most affected their purchase of ready-to-wear lower body clothing was the design followed by the size. The women, especially of the ages 50 to 59, showed a tendency to he dissatisfied with their lower bodies and they recognized that their lower bodies had thickened compared to women aged 34 to 39 and 40 to 49. Analysis of body satisfaction, recognition, and fit preference according to girth size showed that the group of larger girth size recognized that their lower bodies were thicker and were more dissatisfied and preferred looser fittings than the groups of smaller women.
