Sixty wild rate (fifty eight of Rattus norvegicus and two R rattus) were caught from Seoul, Kyonggi, Kangwon, Honam, and Yongnam areas between August and October 1992. From liver homogenates of the wild rats, isoenzyme patterns were analysed by starch gel electrophoresis. Using 9 enzyme systems, eight electrophoretic types were identified among wild rats with genetic diversity per locus between 0.00 and 0.49 (Mean 0.15). R rattus from Kyonggi (Kanghwa) and Kangwon (Cholwon) were distinct from R norvegicus from nine regions with 0.581 in genetic divergence. Therefore genetic divergence was different not only in interspecies(0.581) but also in intraspecies(0.111~0.375). These data suggested that isoenzyme electrophoresis could be used as a potential application in taxonomic studies of wild rats.

Sixty eight wild rats, Rattus norvegicus, were caught from Seoul city, Kyonggi, Kangwon, Cholla, and Kyongsang-provinces. All sera collected from rats were examined by immunofluorescent test to find antibody against murine typhus. The antibody prevalance to murine typhus was 4.4%(3/68). Sero-positive rate was 12.5%(2/16) in Kyonggi province and 12.5%(1/8) in Cholla province. The sero-positive rate difference between sexes of rats was not recognized. Three Rattus norvegicus having antibody to murine typhus were morphologically classified as subadult with 8.3%(1/12), middle-aged adult with 5.9%(1/17), and old adult with 4.8%(1/21), respectively.

Diseased leaves of Job's tears were collected at six locations in Korea to isolate and identify the pathogen causing leaf blight. Conidia were brown, fusoid, and slightly curved. They were $25{\sim}46{\times}10{\sim}15\;{\mu}m$ in size, and had mostly 4 septa which were characteristic of pseudosepta. A few conidia had slightly protruding hila, whereas most had no hilum. Conidial germ tubes were produced mostly from both polar end cells (bipolar), and progressed in semiaxial direction. When seedlings of Job's tears were inoculated with conidia, long, spindle-shaped, and brown lesions were produced on leaves, and entire leaves became blighted 15 days later. Based on the aggressiveness in pathogenicity, the isolates could be divided into two groups. Considering the mycological characteristics and pathogenicity of the fungus, the pathogen causing leaf blight of Job's tears was determined to be Bipolaris coicis (Nisikado) Shoemaker.

This study was carried out to determine distribution and tuberization characteristics of tubers of water chestnut(Eleocharis Kuroguwai Ohwi) which is a dominant weed species and diffult to control during 1993 to 1994. By early planting of E. kuroguwai tubers, more and heavier tubers were developed, but the tubers were tended to distribute at the upper soils. Large proportion of tubers was remained at the upper 0 to 10cm soil layer and a few tubers were formed below 20cm. Tubers developed earlier tended to be at deeper layer, while later developed tubers were at upper layers. Tuber weight was increased from the surface to 20cm soil depths, but that formed below 20cm was almost same. No tillage resulted in more tuber formation which were distributed at upper soil layers when compared to conventional tillage. Cool water irrigation pumped from ground water resulted in less tuberization but smaller tubers when compared to control. Shading with color cellophan films resulted in smaller tuber formation with lower in sprouting percentage. Among the films tested, the most significant effect was obtained with green color.

A bacteriocin-producing lactic acid bacterium with inhibitory activity against the growth of Lactobacillus plantarum was isolated from kimchi, a traditional Korean fermented vegetable. For the identification of the isolate, its 16S rDNA was sequenced. As a result, the sequence showed $99\%$ homology with those from Lactobacillus paraplantarum, Lb. plantarum, and Lactobacillus pentosus. For further identification of the isolate, the sequence of its 16S/23S rDNA spacer region was determined, and the sequence matched perfectly with that of Lb. paraplantarum. SDS­PAGE fingerprinting of whole-cell proteins of the isolate was almost identical with that of Lb. paraplantarum. The isolation and identification of Lb. paraplantarum suggest that Lb. paraplantarum is one of the lactic acid bacteria involved in kimchi fermentation.

An ecological survey of early childhood nutrition was conducted from January 23 to February 18, to study the feeding method and weaning practice in Whaseong-gun, Kyonggi-do. This study covered a total of 283 children. Seventy three percent of the subjects had been breast-fed; 10% had been bottle-fed; others had been combination-fed before the introduction of supplementary foods. Only 26.9% of the subjects began to be fed supplementary food before the age of 6 months. The supplementary food used most frequently by the majority of children at the beginning of weaning was plain cooked rice; rarely special preparation, or different from the food eaten by the family. As for age of termination of breast feeding, 42.7% of the subjects were before 12 months; 32.8% were between 13 and 18 months of age; 24.5% were more than 19 months old. As for methods of stopping breast feeding, 44.5% of the subjects were naturally terminated while 38.5% were forced to terminate by the application of sticking plaster or medicines to the mother's nipples. The results indicate a need for nutrition and hygiene intervention to improve the weaning practice of rural area through the community nutrition education.

In the past, commercial advertisements were produced mainly by advertisements that introduced functions, descriptions, or brands that the product had. However, the current advertising market appeals to the product by projecting emotion into the product in line with the consumer's expanded role of storytelling. Nudge effects can help you make the right choice in an economic and behavioral sense. Storytelling, which includes these nudge effects, allows people to communicate with people, thereby allowing consumers and businesses to move in the direction they want. This study understands the concept of nudge effect through commercial advertisement of Seoul Milk and studies the impact of corporate commercial advertisement on the analysis of the interactions between nudge effect and storytelling on the company's perception change as a consumer. The purpose of this study is to study the influence of the nudge effect. The results of this study have affected the perception of the entity, affected by the ripple effect of the nudge effects.

The purposes of this study were to investigate (1) intention perspective taking, (2) cognitive cuing according to infant age, cue type, and emotional-situation fit, and (3) the relationship between a child's intention perspective taking and cognitive cuing. The subjects were 2 groups of 41 infants each aged 3- and S-years-old from two different day-care centers in Seoul and Kyonggi province. Each child was individually interviewed with pictorial tasks. There were significant differences in the children's intention perspective taking according to their age, type of intention, and intention-outcome fit. There were also significant differences in the children's cognitive cuing according to their age, cue type, and emotional-situation fit. A relationship between the intention perspective taking and cognitive cuing was also revealed that is, the thinking and application responses of cognitive cuing were positively related to the children's intention perspective taking.

This study was done to identify a status of home visiting project as a community health nursing system, that was the organization. personal who have age, educational background, marital status, position, experience of the home visiting in the public sectors in part of Seoul. Kyonggi, Kang-won area, It was done to provide basis data for the development of effective visiting nurses project in the health sectors, where was Health Centers in urban and rural. Branch of Health Center in rural and Health posts. The question airs were distributed 352 public health workers who working place was 118 health workers in 12 health centers in Seoul. 56 public health workers among 39 health center and other public health sectors in Kyonggi and 178 public health workers among health center and health care sectors. Data collected from October to December. 2000. The analysis by SAS system with F test, percentage and frequency. The major result were as follows. The general characteristics of the respondent show that most of them were graduates from community college and RN-BS with broadcast that they had not completed CPHN course but only two health workers have trained for the visiting nurses project. As for their grade in the position, the most of health workers have seventh level and the other CHP were above sixth level in the health care post that in the government structure. This indicates that workers do not have great authority in decision making, the most period of works in the position was one and two years indicating that they change jobs frequently. On an average their clinical experience was 4.11 years which is ideal for the total service. As for preparation of staff for home visiting workers education on visiting nurses program have to receive short term or longer term training course for strong emphasis. The analysis showed that public health visiting workers responds about active job performance that based on an area, approach of acting by districts, education and position are shown statistically significant difference between acceptance of the visiting nursing job show the same as well as visiting nurses project. Special concerns for visiting Nursing care spread came to burden, many of activity carry out main solution is covered the health problem connective support system needs of quality and quantity which out health problem. As 71.1% of visiting health service held on the poor population was under the guardianship of the law, but people who health insurance wide application under law shown a tendency to increase gradually. The general characteristics of the patients showed 56.2% of female on average of age was 66.1 years old, they have health problem was the most of 47.6% of high blood pressure and stroke, the other and as a problem that economics, which is complex welfare with out health problem. Community health care service should be combined health and social work program. The form of delivery of visiting health care given the most guide and education with counselling and support. (33.6%) Among the six category of visiting care service shown statistically significant difference and next is fundamental care, remedy care with priority.
