Objectives: The purpose of this study was to investigate the association between practice and infectious diseases in elementary, middle and high school students. Methods: In 16 metropolitan cities and province of the Korea, the students who from fourth grade of elementary school to third grade of high school were surveyed by personal interviews and an web-based online survey from 5 to 25 September, 2014. We analyzed data with chi-square test and logistic regression analysis. Results: Common cold, diarrhea, and eye infections were more prevalent among students in higher grade than lower grade. In particular, common cold was more prevalent among girls than boys, using hand sanitizer than washing with soaps, and students who wash the dorsal side of hand than not wash the dorsal side of hand. Conclusions: Higher-grade students showed low status of hand washing practice. Hand washing was determined as the fact which influences to increase the prevention of communicable disease such as common cold. Considering the fact that youth groups have higher risk of being infected due to their group life, schools are recommended to provide adequate educations regarding proper hand washing practice with soap.

The purpose of this study was to investigate consumers' perceptions on monosodium L-glutamate (MSG) in social media. Data were collected from Naver blogs and Naver web communities (Korean representative portal web-site), and media reports including comment sections on a Yonhap news website (Korean largest news agency). The results from Naver blogs and Naver web communities showed that it was primarily mentioned MSG-use restaurant reviews, 'MSG-no added' products, its safety, and methods of reducing MSG in food. When TV shows on current affairs, newspaper, or TV news reported uses and side effects of MSG, search volume for MSG has increased in both PC and mobile search engines. Search volume has increased especially when TV shows on current affairs reported it. There are more periods with increased search volume for Mobile than PC. Also, it was mainly commented about safety of MSG, criticism of low-quality foods, abuse of MSG, and distrust of government below the news on the Yonhap news site. The label of MSG-no added products in market emphasized "MSG-free" even though it is allocated as an acceptable daily intake (ADI) not-specified by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). When consumers search for MSG (monosodium L-glutamate) or purchase food on market, they might perceive that 'MSG-no added' products are better. Competent authorities, offices of education and local government provide guidelines based on no added MSG principle and these policies might affect consumers' perceptions. TV program or news program could be a powerful and effective consumer communication channel about MSG through Mobile rather than PC. Therefore media including TV should report item on monosodium L-glutamate with responsibility and information based on scientific background for consumers to get reliable information.

The study aims to examine that regular leisure activity of the elderly has a beneficial effect to enhance their health condition. The elderly subjects of 164 (82 of elderly who do leisure and 82 of elderly who do not leisure) aged over 60 years in Suwon area were employed. Survey questionnaires were administered to investigate general characteristics, life style, mental status, dietary life and nutritional status. From the findings, the elderly who do leisure were highly educated, better in living status and higher employment rate. The mental status of the elderly without leisure activity was very much inferior to that of the elderly with leisure activity, representing higher prevalence rate of depression. Furthermore, the elderly who do not leisure showed higher drinking and smoking rates, irregular eating habits, poor teeth condition and chewing style as well as having eating obstacles. Mean caloric intake of both the elderly was also lower than that of RDA. The elderly who do not leisure have shown lower intakes in most of essential nutrients in contrast to the elderly who do leisure. In conclusion, the elderly with regular leisure activity seemed to have better life style and mental status, dietary life and nutritional status. Therefore, it is critically important to establish the health program combined with various leisure activity for the seniors to promote and energize the later years of life.

The perception of Korean housewives was investigated on commercial Korean basic side dishes. The questionnaires were distributed to 464 housewives in Busan area. According to the survey, the housewives preferred discount stores (44.1%) to purchase basic side dishes. The reasons for purchasing them were convenience (54.6%) and readiness in small amount (23.1%). The housewives had high perception scores on saying cooking time (4.90/5.00), the possibility of purchasing when they need (3.93/5.00), and convenient use (3.85/5.00). However, they doubted the propriety of making use of chemical seasoning (2.15/5.00), the original place of raw food materials (2.21/5.00), and shelf life control (2.44/5.00). The satisfaction scores on the commercial basic side dishes were 3.06/5.00 in braised perilla leaves, 2.98/5.00 in braised soybean, 2.96/5.00 in pickled garlic, and 2.96/5.00 in stir-fried/muchim dried fish. The priorities on the improvement demand for the basic side dishes were appeared in order of the sanitary preparation, the consistent tastes, the proper amounts of chemical seasonings, and sanitary distribution systems.

In the industry of landscape architecture, in which the core of production is manpower, the management of manpower is of utmost importance. The industry of landscape architecture, however, is highly sensitive to economic shifts and policy changes; this sensitivity renders the management of manpower-maintaining the balance between supply and demand-often times difficult. Currently, this vicious circle appears to persist in the sense that the industry suffers from a lack of skilled employees, and a new body of skilled laborers from the paucity of jobs. This study, in analyzing current manpower management as well as the prospective supply and demand in the field, looks forward to the stability of the supply and demand in landscape architecture in the nation. According to this study, the number of new skilled laborers-those who have a higher credential than that of "landscape architect-engineer"-is expected to increase by 10% per year. The number of new skilled laborers being 1,137 in 2008, it can be inferred that there will be a new group of 1,251 skilled laborers in the field in 2009. Meanwhile, estimating that the number of current skilled laborers in the field of landscape architecture is 14,783, the demand for new skilled laborers remains approximately 540. The supply of 1,251 skilled laborers outnumbers the demand of 540 by nearly 230%. Hence, the educational institutions of landscape architecture must be prepared to deal with this imbalance between the excessive supply and the lesser demand of skilled laborers. The issue of the excessive supply of manpower is particularly critical, because it may well undermine the competitiveness of the industry as a whole: compared to other related industries such as architecture and civil engineering, for instance. With the customary validation of long work experience no longer in effect, the need for an engineer's license will keep on increasing. It is time that educational institutions took this issue into full account and helped their students to be better qualified and more competent.

This study traces the development of physic gardens in Korea and explores their significance in the history of landscape architecture. For this purpose, records related to physic gardens from medical sources from the period of the Three States to the Joseon dynasty, when herbal medicine was systematized as a field, were searched. Physic gardens had been developed by the time of the late Goryeo and early Joseon dynasties, in the 13th and the 15th centuries. Yakpo(kitchen gardens for medicinal herbs) were cultivated by a group of new high-level officials in the late Goryeo dynasty, when an increasing interest in hyangyak(native herbs) emerged under the influence of the Neo-Confucian perspective on nature, which emphasized locality. The sources analyzed in this study confirm that physic gardens called jong-yakjeon(royal medicinal herb gardens) were in operation in the early Joseon dynasty when policies to investigate, discover, cultivate, and research native herbs were put into place. It is likely that the jong-yakjeon were established at the beginning of the Joseon dynasty as subsidiary facilities under its central medical institutions, the Naeuiwon and Hyeminseo, and then declined in the late Joseon dynasty. Jong-yakjeon can be confirmed to have existed in the mid-15th century. Physic gardens were located in several places outside the Fortress Wall of Hanyang, such as Yakhyeon, Yuldo, Yeoudo, and Saari. The total area encompassed by physic gardens was about 160,000 square meters in the early 18th century. In jong-yakjeon, dozens of medicinal herbs were cultivated, including Schizonepeta tenuifolia var. japonica, Rehmannia glutinosa, and Glycyrrhiza uralensis Fischer, and these gardens were operated by physicians dispatched from the Naeuiwon and dozens of provincial slaves. In conclusion, the jong-yakjeon were similar to the physic gardens of Renaissance medical universities in that they reflected the interest in and development of theories about new herbs, and were similar to the physic gardens of medieval castles and monasteries in terms of species types, location, and function. This paper has limitations in that it does not present the specific spatial forms of the yakpo or the jong-yakjeon. Nevertheless, this paper is significant for the field of garden history because it shows that physic gardens in Korea appeared in the late Goryeo and early Joseon dynasties concomitantly with the development of medicine towards native herbs and functioned as utilitarian gardens to cultivate community remedies.

Purpose : The purpose of this study was to evaluate the outcome of children with juvenile myelomonocytic leukemia(JMML) treated with allogeneic hematopoietic stem cell transplantation(allo-HSCT). Methods : Eleven JMML patients aged 8-39 months underwent allo-HSCT. The sources of grafts were unrelated donors(n=7), HLA-matched siblings(n=3) and an HLA 1-antigen mismatched familial donor. All patients had received chemotherapy ${\pm}13$-cis-retinoic acid(CRA) before transplant, and CRA was used, posttransplant, in six patients. Results : Only three patients were in complete remission(CR) at the time of transplantation. Initial chimeric status revealed complete donor chimerism(CC) in five patients, mixed chimerism(MC) in five and autologous recovery(AR) in one. One patient with MC having persistent splenomegaly eventually turned to CC and CR after rapid tapering of cyclosporine, combined with daily use of CRA. An AR case relapsed shortly after transplant but was rescued with second, unrelated cord blood transplantation. Ultimately, six patients are alive, event-free, with a median follow-up of 15.5 months posttransplant. All three deaths occurred in patients who failed to achieve CC, leading to disease progression. Conclusion : We suggest that graft-versus-leukemia effect play an important role and CRA a possible role in posttransplant leukemic involution in JMML. In patients whose leukemic burden is still high with MC after transplant, early tapering of immunosuppressants and introduction of CRA might provide a chance of a cure for some patients.

A survey was carried out in Seoul Metropolitan area during December of 1993 and January of 1994. The objective of the survey was to provide a useful information for the development and improvement of recycling policies, regulations and systems in Korea. Of the 782 individuals contacted, 473 individuals completed and retured surveys, of which 437 were usable. The results were analyzed using a statistical package SAS(Statistical Analysis System). The results indicated that 86% of apartment area has recycling bins, while only 33% of individual house(detached dwelling) area has those. About half of the respondents felt that food waste is the major source of household waste. The most serious problem to recycle more household waste is to provide space to store recyclables at the source. The majority of Seoul Metropolitans(78.5%) are willing to participate in recycling programs, while 14.4% want to participate only when there are economic incentives or benefits. Respondents who want economic incentives appeared to be low income people. 66.1% of total respondents said that they do not use disposables. However, only 53,0% among respondents under 30 years old answered they do not use disposables. People who graduated from middle high school only and are under 30 years old have tendency to dispose of used milk cartons without rincing and drying, while those who are over 40 years old and graduated from university prefered to rinse and dry used milk cartons before disposal. Regarding disposal of newspapers, only 43.9% of the total respondents separated newspaper from other types of used paper. In the case of alumium cans, 22.5% of the total respondents answered that used aluminum cans are not recyclables. Much higher portion (30. 4%) of the respondents who graduated from middle high school only felt that aluminum cans have no value to recycle. The results indicated that education and information regarding recycling are highly desirable.

The 9.11 demonstrated that terrorist attack could be more serious problem than the war in our modern life. No countries in the world have evaded being a target for terrorists today. As well as South Korea, the whole world must share attentions and responsibilities for fighting against the terrorism. Since the international terrorist groups have expanded their targets from Western countries to Koreans, civilian hostages are no longer other's affair; it became a serious threat to public. Increased Korean investment, trade, missionary, and travel overseas also expanded activity regions worldwide. It also result increased terrorist threats and possible abduction. The number of kidnapping crisis has increased since the terrorists use it as an effective method of sending a message. Piracy refers to a broad range of violent acts at sea, and has traditionally been regarded as common enemies. Piracy constitutes a great threat to the security of navigation as well as to the safety of vessels and crews. Lessons from hostage issues such as Korean hostage crisis in Somalia and Afghanistan show that it can cause criticism on moral issues if armed rescue missions fail or hostages are killed, so the governments and related corporations try to solve it by paying ransom. Terrorists and use these advantages in order to put a huge pressure on the governments. In this study we will look at essential characteristics and types of hostage abductions and recognition of national safety, lessons and solutions to previous Korean hostage cases in overseas. At the same time, it provides a guidelines of the direction in the fighting against terrorist groups and Piracy.

This study is conducted to evaluate economical value of Jeju grassland and validity of its preservation, and draw up several measures to support. To measure its economical value, this study examined its environmental value and social and cultural value. For environmental value, this study used replacement method while it applied CVM method, a widely used method, to assess social and cultural value and two-level two-best choice selection method, which ask questions by assuming virtual circumstances to avoid reflecting some biased opinions. Jeju grassland has multiple functions-environmental functions such as preventing soil corrosion and flood, handling animal excrement, and purifying air, and social and cultural functions such as promoting physical and mental health and providing recreation places. From the results of the feasibility study, Jeju grassland's annual multiple functions are assessed to have a total $397,115{\sim}418,995$ million won worth. In addition, it is found that Jeju visitors recognize Jeju grassland for its functions to contribute to public interests. That is, they think it can provide attractive views and educational and recreational places and promote emotional development. Especially, many people presented their ideas that it be continuously preserved since it is worthwhile for us and our next generations. To preserve grassland's cultural resource, which create a huge economic value like this, the Government has to support a certain amount of financial aid for turning to a better grassland environment and its maintenance to realize environment-friendly livestock farming on Jeju Island and promote its tourism industry and consequently, add more value to Jeju.
