Regardless of the recent observed warmer winters in Korea, more freeze injuries and associated economic losses are reported in fruit industry than ever before. Existing freeze-frost forecasting systems employ only daily minimum temperature for judging the potential damage on dormant flowering buds but cannot accommodate potential biological responses such as short-term acclimation of plants to severe weather episodes as well as annual variation in climate. We introduce 'dormancy depth', in addition to daily minimum temperature, as a complementary criterion for judging the potential damage of freezing temperatures on dormant flowering buds of grape vines. Dormancy depth can be estimated by a phonology model driven by daily maximum and minimum temperature and is expected to make a reasonable proxy for physiological tolerance of buds to low temperature. Dormancy depth at a selected site was estimated for a climatological normal year by this model, and we found a close similarity in time course change pattern between the estimated dormancy depth and the known cold tolerance of fruit trees. Inter-annual and spatial variation in dormancy depth were identified by this method, showing the feasibility of using dormancy depth as a proxy indicator for tolerance to low temperature during the winter season. The model was applied to 10 vineyards which were recently damaged by a cold spell, and a temperature-dormancy depth-freeze injury relationship was formulated into an exponential-saturation model which can be used for judging freeze risk under a given set of temperature and dormancy depth. Based on this model and the expected lowest temperature with a 10-year recurrence interval, a freeze risk probability map was produced for Hwaseong County, Korea. The results seemed to explain why the vineyards in the warmer part of Hwaseong County have been hit by more freeBe damage than those in the cooler part of the county. A dormancy depth-minimum temperature dual engine freeze warning system was designed for vineyards in major production counties in Korea by combining the site-specific dormancy depth and minimum temperature forecasts with the freeze risk model. In this system, daily accumulation of thermal time since last fall leads to the dormancy state (depth) for today. The regional minimum temperature forecast for tomorrow by the Korea Meteorological Administration is converted to the site specific forecast at a 30m resolution. These data are input to the freeze risk model and the percent damage probability is calculated for each grid cell and mapped for the entire county. Similar approaches may be used to develop freeze warning systems for other deciduous fruit trees.

"떡"을 대표로 하는 중국 밀 문화는 선사시기의 야생 식물 재배는 역사상의 가공과 이용으로부터 현대 사회의 정밀 가공, 더 깊은 가공의 광범위한 이용에 이르기까지 수천 년의 긴 역사과정을 거쳤다. 그러나 20세기말 이전까지만 해도 밀가루는 중국 사람의 주식 원료 구성에서 그다지 중요하지 않은 위치에 있었다. 하지만 분명해야 할 것은 어떤 종류의 곡물이 한 민족의 주식 원료 구성에서의 높고 낮은 비중이 결코 간단하게 그 사회 의미와 문화가치의 높고 낮음과는 동일시할 수 없다. 중국 사람의 밀 식용 역사가 바로 하나의 전형적인 사례이다. 선진(先秦)시기, 밀의 재배와 식용은 주로 식량 공급이 줄곧 긴장된 상태에 처해있는 각 정권의 "接濟靑黃"(구제식량)하는 전략적 물자였다. 그러나 선진(先秦)시기에서 밀은 경제가치가 아주 높은 곡물은 아니었다. 그 원인은 밀의 무(畝)생산량이 상대적으로 낮을 뿐만 아니라 종자의 수요량도 상대적으로 크기 때문이다. 묵은 곡식은 다 사용되고 새 곡식이 무르익지 않은 공백기에 있는(청황불접) 시기에 전략적 곡식의 사회와 정치 의미 외에 강한 적응성, 광범위한 분포와 낮은 단가가 또한 밀의 상대적 장점으로 될 수 있다. 밀의 경제와 문화가치는 주로 한대(漢代)이후 차츰 드러났다. 혁명적인 변화는 바로 가루 음식의 섭취와 계속적인 확대이다. 밀을 가루로 내어 식용한 후 차츰 기타 곡물의 편의식품 전통 공간을 대체하였고, 한대(漢代)의 딤섬류 식품 "한구(寒具)(고대에 곡물가루 튀김 음식물 현재의 타래떡 등)"에 사용되는 재료도 거의 밀가루를 사용하였다. 오늘날 중국 사람이 자랑으로 여기는 전통식품인 국수, 만두, 혼돈(餛飩), 포자(包子), 소맥(燒麥), 떡, 찐빵(饅頭), 고(糕) 및 공업화 식품인 과자, 빵, 라면, 햄버거 등은 모두 밀가루를 기본 원료로 사용하고 있다. 나아가서 더욱 정밀하고, 다양한 딤섬 종류도 밀가루를 기본 원료로 한 주요 무대이다. 20세기말 이후 밀 소비 인구가 계속 확대되는 추세였으며 높은 소비량은 밀의 재배 면적 확대와 재배지역 확장을 결정하였다. 밀 소비량은 중국 사람의 주식 원료 소비에서 이미 근근이 벼 뒤를 잇는 지위에 올랐다. 통계 자료에 따르면 1949년 중국 밀 면적은 2,185만 헥타르로, 전국 식량 작물 총 면적의 19.6%, 총 생산량 1,380만 톤으로 전국 식량 작물 총 생산량의 12.2%에 달한다. 1980년에 이르러 면적은 2,884만 헥타르로, 총 생산량은 5,416만 톤에 달하였으며, 각각 식량작물 총면적의 24.8%, 총 생산량의 17.0%를 차지하였다. 1981이후 중국 밀 생산량은 또한, 새로운 발전을 가졌으며, 주로 단위 면적 생산량이 비교적 크게 증가되었고 총 생산량도 큰 폭으로 증가되었다. 1981~1985년과 1976~1980년의 5년 평균치를 비교한 결과 재배 면적은 같았으나(단지 0.2%만 증가), 단위 면적당 생산량 및 총 생산량은 46% 증가하였으며, 연평균 증가율이 9.2%에 달하여 50년 이래에 증가 속도가 가장 빠른 시기였다. 비록 지금 중국인의 "배부르게 먹기"문제는 이미 기본적으로 해결되었으나 장기적으로 "배부르게 먹기"의 물질적 보장은 여전히 취약하다. 농사가 가능한 경지면적의 급속한 격감으로 단위 면적당 생산량의 압력을 증가되었다. 국가 표준에 따르면 품질이 좋은 밀은 "탄력이 강한 고품질 밀"과 "탄력이 약한 고품질 밀" 두 가지로 구분된다. 지금 중국 시장의 추세를 보면 밀 품종의 선택에서 주로 탄력이 강한 고품질 밀을 선택하는데 즉 글루텐량이 높고 탄력이 강하며 품질이 좋은 전문 용도에 사용되는 밀을 선택한다. 탄력이 강한 고품질 밀은 주로 빵, 라면, 만두 등 밀가루 탄력을 요구하는 음식을 만드는데 사용된다. 그 중에서 모든 빵은 탄력이 강한 고품질 밀을 사용하고 밀에 대한 품질 요구도 또한 높다. 빵가루의 품질을 높이기 위하여 일부 전문 밀가루 생산 공장에서는 국산 고품질 밀에 수입 고품질 밀을 첨가하여 사용한다. 만두가루를 가공할 경우도 고품질 밀을 첨가하여 밀가루의 품질을 높이고 음식을 맛을 증가한다. 일부 품질이 떨어진 밀에 대하여 고품질 밀을 첨가하여 내부의 품질을 개선하고 찐빵이나 기타 밀가루 음식으로 가공한다. 예를 들면 중국 동북 지역에서는 고품질 밀과 봄밀을 섞어 밀가루의 봄밀의 품질을 개선한다. 총괄적으로 밀에 대한 욕구는 계속 장기적으로 벼에 버금가는 위치를 유지할 것이며 고품질 밀에 대한 욕구는 더욱 강한 추세로 발전할 것이다.

The nutrient contents of pumpkins depend on many factors, including the species, climate, soil type, and plant part. The nutritional compositions of five pumpkin cultivars (red boujjang, mini hong, mini gold, boujjang, and yakhobak) were investigated. To analyze the nutrient contents of the edible parts, the other parts (seeds, skin, and stem) of each pumpkin were removed. The results showed that the proximate compositions of the edible parts of the pumpkins ranged from 74 to 87 g per 100 g for moisture, 1.6 to 3.2 g per 100 g for crude protein, 10.1 to 20.7 g per 100 g for carbohydrate content, and 2.0 to 3.4 g per 100 g for total dietary fiber. The proximate contents of the pumpkin samples were not significantly different. The thiamine contents of the pumpkins, except for red boujjang, varied from 0.03 to 0.15 mg per 100 g, but that of red boujjang had the highest level (0.60 mg per 100 g). The vitamin C contents of the pumpkins, except for boujjang, ranged from 13.0 to 14.0 mg per 100 g, but that of boujjang was the highest (49.0 mg per 100 g). In particular, yakhobak showed the highest total carotenoid and folate levels (279.5 and $74.0{\mu}g$ per 100 g, respectively). These results will be useful for coming up with better pumpkin varieties through breeding, and established the nutrient compositions of pumpkins.

Burglary (also called breaking and entering and sometimes housebreaking) is a crime, the essence of which is illegal entry into a building for the purposes of committing an offence. It is one of the most common types of crime and also a serious issue for every society. A house that is left insecure is an accessible and attractive target for burglars and therefore burglary resistance test & certification system for doors and windows has been developed in many countries. This paper explores several advanced foreign burglary resistance test/certifcation cases (the British SBD, the Dutch KOMO SKH/SKG, the Japanese CP mark, the Australian Standard Certification) for security products and domestic test/certification systems for fire safety products as a comparative study so that any improvement points can be gained for South Korea in the field of security product performance. The comparative analysis results show that South Korea is far behind the security product certification system and needs a lot of improvement in the system by benchmarking foreign cases. The domestic test/certification systems for fire safety products also give some insights for burglary-related security products' performance certification system in Korea. Overall, the need for relevant rules and regulations, the establishment of standards regarding testing and certification, including certified security +hardware product in building security certification system, performance testing as well as production testing (i.e. quality management system evaluation), the basic competency of testers, incentive system for certified/high quality security products were suggested in order to make an optimal model for the security production performance testing and certification system in Korea.

NCS education was created to realize a society in which skills and abilities are respected, such as transcending specifications, establishing recruitment systems, and developing and disseminating national incompetence standards. At the university level, special lectures and job training are being strengthened to raise industrial experts. Especially, in the field of animation, new technologies are rapidly emerging and demanding convergent talents with various fields. In order to meet these social demands, there is a limit to the existing one-class teaching method. In order to solve this problem, it is necessary to participate in a variety of specialized teachers. In other words, rather than solving problems of students' job training and job creation, It is aimed to solve jointly, Team teaching was suggested as a method for this. The expected effects that can be obtained through this are as follows. First, the field of animation is becoming more diverse and complex. The ability to use NCS job-related skills pools can be matched with professors from other departments to enable a wider range of professional instruction. Second, it is possible to use partial professorships in other departments by actively utilizing professors in the university. This leads to the strengthening of the capacity of teachers in universities. Third, it is possible to build a broader and more integrated educational system through cooperative teaching of professors in other departments. Finally, the advantages of special lectures and mentor support of college professors' pools are broader than those of field specialists. A variety of guidance for students can be made with responsible professors. In other words, time and space constraints can be avoided because the mentor is easily met and guided by the university.

This study utilized the 1/25,000 topographic map of the upper area from the Geum-ho watermark located at the middle of Geum-ho river from the National Geographic Information Institute. For the analysis, first, the influence of the size of critical area to the hydro topographic factors was examined changing grid size to $10m{\times}10m,\;30m{\times}30m\;and\;50m{\times}50m$, and the critical area for the formation of a river to $0.01km^2{\sim}0.50km^2$. It is known from the examination result of watershed morphology according to the grid size that the smaller grid size, the better resolution and accuracy. And it is found, from the analysis result of the degree of the river according to the minimum critical area for each grid size, that the grid size does not affect on the degree of the river, and the number of rivers with 2nd and higher degree does not show remarkable difference while there is big difference in the number of 1st degree rivers. From the results above, it is thought that the critical area of $0.15km^2{\sim}0.20km^2$ is appropriate for formation of a river being irrelevant to the grid size in extraction of hydro topographic parameters that are used in the runoff analysis model using topographic maps. Therefore, the GIUH model applied analysis results by use of the river level difference law proposed in this study for the explanation on the outflow response-changing characters according to the decision of a critical value of a minimum level difference river, showed that, since an ogival occurrence time and an ogival flow volume are very significant in a flood occurrence in case of not undertow facilities, the researcher could obtain a good result for the forecast of river outflow when considering a convenient application of the model and an easy acquisition of data, so it's judged that this model is proper as an algorism for the decision of a critical value of a river basin.

Studies on the role of agricultural science colleges are mostly divided into agricultural production, which is the primary function of agriculture, and other functions, which have recently begun to be emphasized as a result of social needs. With the green revolution and the aging of the farming population, there is a strong view that the role of agricultural science colleges should remain as it is. However, agriculture is expanding in terms of concept and content by converging with other industries not traditionally associated with agricultural production. Thus, the fields that now need to form part of agricultural science knowledge are becoming more detailed and expansive. The government's perception remains at the level of merely fostering farmers. This was evident in a survey on the employment rate, a factor used to evaluate colleges, in which the role of agricultural science colleges was limited to fostering farmers. Agro- industry fields, other than agriculturalists, include general industries in which the academic fields of agricultural science are combined with other academic fields. Thus, even when someone is employed in an industry that requires background knowledge of agricultural science, there is often a perception that he or she is employed in a field that is irrelevant to the major. This study examines the role of agricultural science colleges in agriculture and farm villages by focusing on the employment of graduates of these colleges within agro-industry. We categorize academic research on agricultural science into 16 fields, based on the medium level of the National Standard Science and Technology Classification Codes. Then, we categorize the employment fields into 168 fields, based on the small classification level of the inter-industry relations classification. Thus, we investigate 220 departments of 37 colleges, nationwide. Our findings show that the average employment rate of graduates of agricultural science colleges is 69.0%. Furthermore, 33.0% of all employees work in agro-industry fields that require background knowledge in agricultural science, which is one out of three job seekers. Then, 3.6% of employees work in business startups in agro-industry. The aforementioned government survey showed that only 0.1% of all college graduates in Korea were employed as agriculturalists in 2013. However, our results showed that 13.3% of graduates were working as agriculturalists, which is significantly different to the results of the government survey. These results confirm that agricultural science colleges contribute greatly to the employment of graduates, including farmers, agro-industry, and business startups in agro-industry fields.

This study investigated the correlation between eating behavior patterns, including eating-habits, food preferences, snack intake levels, and eating-out frequency and stress levels in high school students (males 174 and females 122) in Seoul. Analysis of eating-habits showed that eating-irregularity and eating-speed increased with elevated stress levels in both males and females under stress. The size of meals decreased in males, whereas it increased in females under getting stress (P<0.01). Preferences for sugar, hamburgers, and pizza also increased in both males and females under stress. Eating-out frequency decreased in males with a high stress level (P<0.01), whereas it increased in females. As for eating-out partners, males did not show any changes, whereas females preferred friends to family when under stress. Eating-out expenses also increased in both males and females, particularly in females with a high stress level (P<0.05). Males under increased stress showed effective stress reduction by increasing food intake, whereas females under increased stress showed less effective results. Consequently, high school students under high stress, particularly females, showed negative changes in eating behavior patterns, including irregular eating-habits, increased instant food and snack intakes, and increased frequency of eating-out. Therefore, development of appropriate programs for reducing stress and persistent nutrition education to promote good dietary behaviors are required.

In this research, an empirical analysis was performed to determine the correlation between management performance and R&D investment for domestic venture businesses in each industry. Specifically, an empirical analysis for each industry was attempted not only to clarify the general hypothesis on the relationship between management performance and R&D investment for venture businesses but also to demonstrate that differences exist for each industry. Empirical analysis was conducted for eight industries with respect to the $2002{\sim}2006$ panel data extracted as investigative results from the "Investigation Report on Science and Technology R&D Activities" published by the Ministry of Science and Technology. Industrial classification was limited to the middle-level classification (2-digit) in the Korea Standard Industry Code (KSIC) owing to the limited number of panels. Although this research only verified the overall positive effect of R&D activities and funds for existing research on corporate value or productivity and management performance, it was able to document the difference for each individual industry and each business size unlike existing research.Furthermore, the reliability of the research results was enhanced by targeting companies that have been continuously conducting R&D and management activities using consistent 5-year panel data in the analysis. Again, this was something that existing research did not have. Finally, through the use of recent data from 2002 after the IMF economic crisis up to 2006 in the empirical analysis, this research proposed the problems due to the prevailing circumstances at the time of entering the advanced nation stage based on an empirical analysis; the prevailing problems during the pursuit of advanced nation status before the IMF crisis broke out were not tackled. The key empirical analysis yielded several results. First, capital and size of the labor force have a positive correlation with the management performance for the entire company or the venture business. This applies to all eight industries as the subjects of the analysis. Second, although the number of years since a company has been established can have positive or negative correlation with management performance for the entire company or venture business in specific industries, a definite overall trend cannot be identified. Third, R&D investment can be said to have an overall positive effect on corporate management performance. Fourth, the size of the research staff cannot be said to be a factor unilaterally affecting the management performance of the entire company or the venture business. Fifth, the number of years a research institute has been in operation, which was assumed to have a positive effect on the management performance of a company because of the accumulated R&D know-how -- definitely acts as a positive factor contributing to the management performance of a company.

The use of information on natural resources is indispensable to most agricultural activities to avoid disasters, to improve input efficiency, and to increase lam income. Most information is prepared and managed at a spatial scale called the "Hydrologic Unit" (HU), which means watershed or small river basin, because virtually every environmental problem can be handled best within a single HU. South Korea consists of 840 such watersheds and, while other watershed-specific information is routinely managed by government organizations, there are none responsible for agricultural weather and climate. A joint research team of Kyung Hee University and the Agriculture, forestry and Fisheries Information Service has begun a 4-year project funded by the Ministry of Agriculture and forestry to establish a watershed-specific agricultural weather information service based on "high definition" digital climate maps (HD-DCMs) utilizing the state of the art geospatial climatological technology. For example, a daily minimum temperature model simulating the thermodynamic nature of cold air with the aid of raster GIS and microwave temperature profiling will quantify effects of cold air drainage on local temperature. By using these techniques and 30-year (1971-2000) synoptic observations, gridded climate data including temperature, solar irradiance, and precipitation will be prepared for each watershed at a 30m spacing. Together with the climatological normals, there will be 3-hourly near-real time meterological mapping using the Korea Meteorological Administration's digital forecasting products which are prepared at a 5 km by 5 km resolution. Resulting HD-DCM database and operational technology will be transferred to local governments, and they will be responsible for routine operations and applications in their region. This paper describes the project in detail and demonstrates some of the interim results.
