Tomato fruits(Lycopersicon esculentum $M_{ILL}$.) picked at mature (from mature green to breaker) and ripe (from pink to red) stage were packed into two layers in corrugated fiberbox and transported 200km and 400km from the harvested site. Loss (abrasion + cracking) in marketability was lowest (11.0%) from mature + 200km transport, followed by mature + 400km transport(13.5%), ripe + 200km transport(28.5%), and ripe + 400km transport (45.5%). When data were pooled by fruit maturity, firmness of mature fruit was 1.55 times higher than ripe fruit. However, vitamin C content was 1.25 times higher in ripe fruit than in mature fruit. Fruit transported longer distance and packed in bottom layer within a box exhibited lower firmness and vitamin C content in both maturity. It was concluded that it is desirable to transport relatively shorter distance for ripe tomato and longer distance for less ripe fruit.

This study was designed to determine the best cultivar of kohlrabi for making pickles among KM-1 (Worldcol), KM-2 (Bejo), KM-3 (Takii), and KM-4 (Monsanto) cultivars. The initial pH of pickles was different in all cultivars; however, they all had a pH in the range of 3.81~3.86 after 28 days of storage. The pickles made from KM-4 had the lowest acidity, while there was no significant difference in acidity among the KM-1, KM-2, and KM-3 pickles. The salinity of all kohlrabi pickles was consistent during the storage period. The changes of color values were accelerated in the following order: KM-4>KM-1>KM-2>KM-3. Though kohlrabi pickles were non-fermented, the change in reducing sugar contents was similar to that of a fermented pickle. The highest value of reducing sugar content was found in pickles made with KM-4. In all cases, the firmness of the pickle decreased as time of storage increased. On the initial day, KM-4 pickle showed the highest firmness with 807.4 g. KM-4 also showed the highest firmness on the 28th day of storage with 602.3 g. In sensory evaluation, the KM-4 pickle exhibited the highest texture (hardness) among the pickles. The pickle made with the KM-4 cultivar showed relatively higher firmness of texture than other cultivars, suggesting that KM-4 could be utilized in other kinds of processed foods, in addition to being pickled.

Thermal spatial representativities of meteorological stations over Korea have been investigated using land surface temperature (LST) based on MODerate resolution Imaging Spectroradiometer (MODIS) satellite observation. The linear regression method was used to estimate air temperatures from MODIS LST product. To compare MODIS LST with observed air temperatures at six meteorological stations, the mean values of MODIS LST with nine given window sizes were calculated. In this case, the position of centered pixel in each given window size is correspond to that of each meteorological station. We also applied $4^{\circ}C$ threshold for RMSE comparison, which is based on a analogous study on daily maximum air temperature model using satellite data. In this study, the results showed that each station has a different representativity; Deajeon $15km{\times}15km$, Chuncheon $11km{\times}11km$, Seoul $7km{\times}7km$, Deagu $5km{\times}5km$, Kwangju $3km{\times}3km$, and Busan $3km{\times}3km$.

In order to explore a relationship among KM context, KM effects, and sustainability of competitive advantage of organizations, a contingency model of KM, which is based on resource-based as well as knowledge-based theory, is developed from the information systems and strategic management literature. To put it concretely, our motivation for this paper was to answer the following questions: (1) What factors affect the degree to which an organization achieves KM effects? (2) Is there a positive relationship between KM effects and organizational performance achieved by linking KM to competitive advantage? A detailed exploratory analysis of survey responses from 79 Korean companies provides the following significant findings: (1) This study found support for the proposed research model. (2) The organization's degree of process and organizational outcomes of KM effects is determined by technical and social resources and its capabilities. Furthermore, the influence of technical and social resources of KM context on process and organizational outcomes of KM effects is controlled by different types of organizational perspectives on KM. (3) There is a relationship between process and organizational outcomes of KM effects and organizational performance enhanced by linking KM to competitive advantage.

Backgrounds: The demand of complementary and alternative medicine (CAM) including Korean Medicine (KM) is increasing worldwide. But cancer patients (CP) still have a difficulty in gathering CAM information or communicating with their doctors, and clinical status in cancer care is unclear in the field of KM in Korea especially. The aim of this study is to examine clinical status of KM for cancer symptom care by KM doctors in medical service institutions. Methods: Total forty nine KM doctors completed the site survey questionnaire. The questionnaire items were to list chief symptom complaints of CP treated with KM and effective KM therapies. Results: The majority of the respondents were general physicians without KM specialist board (67.4%) who have 10-20 years clinical experience with CP (55.1%). Primary cancer lesion, diagnostic status, and treatment period were not different in KM clinical service institutions. In chief symptom complaints of CP treated with KM, gastrointestinal (32.9%), musculoskeletal (19.9%), circulatory & respiratory (16.2%), psychiatric (14.1%), urinary (5.8%) symptoms were in turn. In effective KM therapies assessed by KM doctors, xerostomia (45.7%) and cancer-related fatigue (44.8%) were more effective with herbal treatments. Peripheral neuropathy (43.4%), depression, insomnia (38.2%), and cancer pain (31.9%) were preferred to treat using acupuncture. Conclusion: The CP treated with KM used evenly KM medical service institutions regardless of hospital size, and there will be further survey for CP treated KM in the future.

66 samples of underground waters at the town Onyang were collected and analyzed from August 19 to November 5, 1969. Fluorine more than 1.0 mg/l is contained in the under ground waters in the region 0.9 km away from the Onyang hot springs, fluorine more than 0.3 mg/l in the waters in the region 1.2 km away from the hot springs, and 0.04-0.29 mg/l fluorine in the waters in the region from 1.2 km to 3.9 km away from the hot springs. It is advisable that the residents in their teeth growing ages must not drink the underground waters in the region 1.2 km away from the hot springs because the waters cause dental trouble (mottled teeth) and they may drink the waters in the region from 1.2 km to 3.9 km away from the hot springs for the fluoridation of their teeth. It is reasonable to suppose that the high fluorine contents of the underground waters are caused mainly by the contamination of the hot spring waters in which fluorine and calcium in rock are dissolved, in the region 1.2 km away from the hot springs, and that the waters in the region from 1.2 km to 3.9 km away from the hot springs contain much fluorine produced by the decomposition of organic substances.

This study is an attempt to present a model of the effective service area for branch library system planning in Dae Gu city as one of large urban public libraries in Korea. This model is built up through the analysis of the distribution of population and characteristics of community structure, based on the standard for the branch library system of a public library. The results are summarized as follows: 1. Under the circumstances of this country, each radius of the effective service area for branch libraries are as follows; $1{\sim}1.5km$. is adequate for the central library and major branches; 1km. for neighborhood branches; $0.5{\sim}0.8km$. for sub-branches. 2. Population within the radius of the effective service area of a given branch may range from 80,000 to 100,000 for major branches, from 50,000 to 60,000 for neighborhood branches, and from 20,000 to 30,000 for sub-branches. 3. The radius of the outer boundary for the effective service area may be between 4km. and 5km. from the heart of the city, and the inner boundary, 13.km. 4. Areas with the radius between 2km. and 3km. from the heart of the city may be selected as the most effective locations for branch libraries, and between 3km. and 4km. as the next priority. 5. The number of service areas may be 14, that is, 7 major branches(Sinam, Sinchun, Susung, Daemyung, Naedang, Dalsung, Rowon), 2 neighborhood branches (Pyungri, Nambu), and 5 sub-branches(Chimsan, Sangiuk, Bongduk, Hyomok, Dongchon)
