This article surveys the fashion forecasting industry in Korean domestic markets. With the rise of new media and devices with high technology, the paradigm of fashion trends forecasting systems has dramatically changed. New perspectives of trend forecasting are required to understand the trend flow and consumer behavior of the MZ generation. The research questions are as follows: 1) Major trend forecasting companies studied the development of their strategies and new forecasting methods. 2) The consumers' needs in the domestic market were analyzed. The influence of the trend companies' forecasting on the market was investigated. The results are as follows: 1) International trend forecasting significantly affected the domestic market. The concordance rate between consumers' online searches about fashion trends was approximately 70.14%. The match rate by category is as follows: The highest rate, 85.06% is from pattern and print, color is 83.92%, the item is 80.39%, and style is 54.32%. 2) Specialized information such as the Pantone color chart is being widely consumed, leading to a trend among the masses. 3) The Korean-specific socio-cultural background has an impact on domestic trends.

Purpose - This study quantifies sources of trade balance dynamics over the business cycle in Korea. Specifically, we quantify the relative importance of domestic and foreign factors on trade balance dynamics using a small open economy real business cycle (SOE-RBC) model and provide policy implications for stabilization policies. Aggregate productivity and interest rate spreads are considered domestic factors affecting the trade balance. A world interest rate (the U.S. interest rate) is considered a foreign factor. Design/methodology - Following Neumeyer and Perri (2005), we build the SOE-RBC model with three types of shocks: aggregate productivity, interest rate spread, and world interest shocks. The model is estimated by the generalized method of moments (GMM) using relevant business cycle statistics. The estimated model is used for quantifying the relative importance of domestic and foreign factors on trade balance dynamics in Korea. Findings - Our main findings can be summarized as follows: 85.64% of the trade balance fluctuations in Korea are explained by domestic factors, the remaining 14.35% by foreign factors. Particularly, trade balance dynamics are mostly accounted for by the change in aggregate productivity shocks (85.58%). World interest rate shocks considerably explain trade balance (14.35%), whereas the role of interest rate spread shocks that represent domestic risks is limited (0.08%). Although aggregate productivity is key in explaining trade balance dynamics in Korea, interest rates still have an essential role. This is because aggregate productivity changes induce interest rate spread variations and, thus, the trade balance significantly. The results suggest that government policies mitigating fluctuations in aggregate productivity would be effective for stabilization policies in Korea by reducing the trade balance volatility. Originality/value - Existing studies on the emerging market business cycle examine mostly Latin American countries, and the main object of the studies is the volatility of consumption rather than trade balance dynamics. Conversely, our study examines Korea rather than Latin American countries. Additionally, we examine sources of trade balance dynamics, which are relatively more important in Korea, rather than those of the volatility of consumption. Hence, we estimate the model to explicitly match moments related to trade balance in the data.

One of the important design issues for IP routers responsible for packet forwarding in computer networks is the route-lookup mechanism. For each incoming packet, IP routing requires that a router performs a longest-prefix-match address lookup in order to determine the next hop that the incoming packet should be forwarded to. In this paper, we present a new scheme which applies the hashing function for IP address lookup. In the proposed scheme, the forwarding table is composed of multiple SRAMs, and each SRAM represents an address lookup table in each prefix. Hashing function is applied in order to find out the matching entries from the address lookup tables in parallel, and the entry with the longest prefix match among them is selected. Simulation using the MAE-WEST router example shows that a large routing table with 37000 entries can be compacted to a forwarding table of 300 Kbytes in the proposed scheme. It is also shown that the proposed scheme achieves one route lookup every 1.93 memory accesses in average.

The two most popular virtual machine allocation schemes, both match making and round robin, do consider hardware specifications such as CPU, RAM, and HDD, but not CPU usage, which results in balanced resource distribution, but not in balanced resource usage. Thus, in this paper a new virtual machine allocation scheme considering current CPU usage rate is proposed while retaining even distribution of node resources. In order to evaluate the performance of the proposed scheme, a cloud computing platform composed of three cloud nodes and one front end is implemented. The proposed allocation scheme was compared with both match making and round robin schemes. Experimental results show that the proposed scheme performs better in even distribution of overall CPU usage, which results in efficient load balancing.

This study aimed to investigate whether breed, sex, and age affected temperament differently (more or less neophobic) in mature horses during a novel object test. The study included Jeju crossbred (n = 12, age = 9.42 ± 4.57 y), Thoroughbred (n = 15, age = 10.73 ± 3.09 y), and Warmblood horses (n = 12, age = 13.08 ± 3.55 y) with the females (n = 22, age = 11.36 ± 4.24 y) and geldings (n = 17, age = 10.65 ± 3.66 y). Jeju crossbreds (Jeju horse × Thoroughbred) are valuable considering their popular usage in Korea, but limited studies have explored temperament of Jeju crossbred horses. A trained experimenter touched the left side of the neck with a white plastic bag (novel object). The test ended when the horse stopped escape response and heart rate (HR) dropped to baseline. Behavioral score and escape duration were measured as behavioral variables. Multiple variables related to HR and heart rate variability (HRV) were measured to reflect emotional state. These included basal HR (BHR), maximum HR (MHR), delay to reach maximum heart rate (Time to MHR), standard deviation of beat-to-beat intervals (SDNN), root mean square of successive differences (RMSSD), and ratio of low to high frequency components of a continuous series of heartbeats (LF/HF). Statistics revealed that Thoroughbreds had significantly higher behavioral scores, and lower RMSSD than Jeju crossbreds (p < 0.05), suggesting greater excitement and fear to the novel object in Thoroughbreds. None of the behavioral or cardiac parameters exhibited sex differences (p < 0.05). Age was negatively correlated with SDNN and RMSSD (p < 0.05), indicating that older horses felt more anxiety to the novelty than younger horses. Thoroughbreds and females had distinct correlations between behavioral and HRV variables in comparison with other groups (p < 0.05), implying that escape duration might be a good indicator of stress, especially in these two groups. These results are expected to improve equine welfare, safety and utility, by providing insights into the temperament of particular horse groups, to better match reactivity levels with specific functions.

This study, based upon the Sturges' crisis stages, examines the crisis response communication strategies of Korea Professional Football League(KPFL) for the K-league match-fixing case as well as the frequency of related news articles and the source of information. To explore the crisis response communication strategies the Korea Professional Football League used, a total of 118 news articles were analyzed using the content analysis and frequency analysis. The unit of analysis for crisis response communication strategies is sentence. The frequency of news articles based upon the crisis stages shows highest rate at the acute crisis stage. The source of information for news reports shows that KPFL was one of the major sources of the news reports. KPFL's crisis response communication strategy throughout all stages of the crisis stage shows that corrective action strategy was used highest ratio. In particular, the crisis response communication strategy between team, player and KPFL was shown lack of consistency throughout all crisis stages. Implication and future research direction for the results are discussed.

Pusan and Seoul(158 people) and 6 high schools(131 people). And these results were derived from percentage and cross analysis of Person Chi-square test ann interview and 47 questioned paper based on this purpose of study. 1. There were no significant differences between high school students and university students in the comprehension of physical therapy and injury occurrence by technique. 2. According to the relation between satisfaction of life as a player and injured part, the injury of soft tissue ranked high among satisfied and unsatisfied people. and the satisfaction or unsatisfaction of practicing place also derived same result. 3. $46.8\%$ of Ssirum players got the injury of soft tissue during practice. the articular injury and bone injury in regular sequence. But there were no relations between the time of injury and the sort of injury. 4. There were no statistical differences ortho sort of injury by technique.(p=0.399). 5. According to the part of injury by using techniques, the injury of soft tissue ranked high$(50.0\%)$, articular injury ranked high$(42.6\%)$ in the leg technique, bone injury ranked high in the leg technique, and nerve injury ranked high in hand technique. 6. The injury of soft tissue ranked high during the practice$(46.8\%)$, practice on the purpose of a match$(50.0\%)$ and match$(41.7\%)$ but there were no relations between the time of injury and son of injury. 7. The part of injury by technique ranked high in the soft tissue$(50.0\%)$, articular injury by leg technique$(42.6\%)$, bone injury in leg and waist technique and nerve injury in hand technique high. 8. The time of injury ranked high during the practice$(65.7\%)$, and $66.1\%$ of injury occurred in the afternoon. 9. During the practice, the cold weather ie related on the rate of injury because $67\%$ of injury occurred in winter, but there are no statistical significance. 10. There were no relations between the satisfaction of place far practice and time of injury. 11. The particular part of injury occurred very much during the match between defense and offense. 12. In the relation between the degree of understanding of physical therapy and the experience of physical therapy, the people who know physical therapy had much experiences of physical therapy(p=.000) And independent of the physical therapy experiences, the effectiveness of physical therapy therapy to players was $48.8\%$, no idea was 42.65 and no effectiveness was $8.7\%$(p=.000). 13. $59.6\%$ of the people admitting the physical therapy effectiveness answered they would follow the order of the doctor and $56.6\%$ of the people not admitting the physical therapy effectiveness answered no.

Proportion of senior population living alone in South Korea has exceeded over 20.2% in 2012, and it is anticipated that the proportion would increase every year. Poverty rate of seniors living alone in Korea is also anticipated to increase the highest rate (76.6%) among OECD countries. In particular, seniors lacking family support are having greater difficulty and isolated due to high housing costs and housing instability. Therefore, they need a new housing alternatives for considering their economical difficulty and lacking family and social support. This study attempted to examine possibility to develop a new housing alternatives for Korean seniors, especially living urban area. For this purpose, this study identified the attitudes and preference for a new house alternatives(Senior Shared House) by Korean seniors living alone. The key findings of this study were as follows: 1) Eighty-five percent of seniors participated in this study responded the senior shared house was needed. 2) It should be developed by utilizing or renovating and renting out existing housing in city areas. 3) Pre-residence checklist can be developed to connect and match prospect residents. 4) Professional workforce (e.g. housing welfare professional) is absolutely necessary to perform the role of coordinator understanding the various characteristics of the seniors, and their living requirements. Recommendations and directions for future development of senior shared house were suggested.

Ch1 a abundance, Ch1 a-specific productivity and phytoplankton growth rate in each size fraction (pico, $<2{\mu}m$; nano, $2-10{\mu}m$; micro, > $10{\mu}m$) in the waters around the South Shetland Islands (Ant-arctic Peninsula Area) were analysed. Although Ch1 a-specific productivity and growth rate were highest in micro-size fractions, ChI a abundance was highest in pico-size fractions. Selective removal of nano- and micro-size phytoplankton especially by krill and salp grazing, but not limitation of phytoplankton growth, seemed to be the major reason to explain this miss match between productivity and abundance of the phytoplankton community.
