The status of corn genetic diversity in the uplands of Sarangani in Southern Philippines was investigated using 12 morphological traits subjected to multivariate statistical analyses. Information about traditional farming, post-harvest and storage practices were also elicited especially in relation to losses of traditional varieties, a phenomenon known as genetic erosion. While a handful of farmers still plant traditional corn varieties in the remotest areas, a significant number had already shifted to genetically modified corn. Furthermore, principal component analysis (PCA) reduced the 12 morphological traits into 5 principal components and identified ear length and ear weight to be major contributors to variation. Cluster Analysis, on the other hand, formed two distinct groups but failed to give information about intra-cluster variability among the 32 collected corn accessions. These results warrant that more informative morphological traits and that molecular markers will be used to obtain a better picture of genetic diversity in Sarangani upland corn. Molecular analysis is also needed to establish genetic identities of these cultivars and to detect gene introgression from GM varieties into the gene pool of farmers' corn varieties. These analyses are imperative for the conservation of traditional corn varieties before they disappear in the Sarangani uplands because of shifting priorities of upland farmers.

Until now, occurrence of rice stripe virus (RSV) is limitted in southern part of Korea. However, recently the occurrence of RSV is increased and spreaded in central part of Korea including Chungcheong and Kyonggi province. It is very difficult to distinguish RSV symptoms on virus symptom physiological damage of rice. We detected RSV viral RNA from infected rice and its insect vector Laodelphax striatellus using specific primer of RSV-polymerase and coat protein gene with reverse transcription (RT)-PCR. The result of RT-PCR, we observed specific band including RSV-polymerase (1,,023 bp) and CP (969 bp) in both host of rice and insect vector.

The present study was undertaken to develop the kit for indirect immunofluorescence antibody test(IFAT) and to investigate the prevalence of N caninum in cattle and dogs in Korea. The neo-antigen kit of IFAT developed in our laboratory was proved diagnostic efficacy by compared with the kit of veterinary medical research and development(VMRD). A survey of N caninum infections among cow and dogs in elevn areas of southern part of country was performed using a IFAT. The infection rate of 190 nationwide cattle was 8.4%(16/190) but was 75%(45/60) at P area in Chunnam province where the cattle showed the abortion repeatedly. Any of the dogs was not N caninum -positive in the Kangwon and Kyonggi areas.

On September in 1998, a microsporidian infection was recognized in ayu, Plecoglossus altivelis, farmed on Kyongnam province of South Korea. Cumulative mortality was around 10% in 10 days. Infected fish which were piping for air near the surface of the water or in the asphyxic, lethargic condition revealed darkening of body and abdominal distention. Numerous whitish nodules up to 3mm in size were observed throughout most of body organs and tissues including gill, operculum, peritoneal wall and organs. Xenomas were also histologically confirmed in multiple internal organs with the evidences suggesting circulatory disturbance. Based on the morphology of spore and xenoma, and the distribution of xenomas in organs and tissues, this disease was diagnosed to be a microsporidiosis caused by Glugea plecoglossi. The mortality might be deeply related to the local circulatory disturbance by xemonas rather than the mechano-chemical effect of xenomas on adjacent tissues.

A study on the traditional houses of North Korea(I) have been published in 1996. This paper is written to supplement the preceding paper. This paper aims at collecting new data of traditional house in North Korea. But still being prohibited for the researchers of South Korea to approach to the field, I had to depend on the memories and experiences of the immigrants from North Korea who are now living in Kangwon and Incheon Province. Through the questionnaire and drawings, they described vivid memory of their old houses. I was able to add new data of 70 cases, which are significant and valuable as much as those of the real field are. Those data, including the exisiting data, are enough for me to analize statstically the regional charateristics, the differnces among economical classes, and the periodical change. It opens the way for verfying the existing theory. Regional charateristics of house in North Korea can be described as followings: a. Hamkyong-do ; Concentrating spaces into one building, Double-fold type plan, Including 'cheongju-kan' space, Weak fences b. Pyongan-do ; Concentrating spaces into two buildings, 二 shape buildings , Single-fold type plan, Strong fence c. Pyongannam-do to Myolak mountains; Concentraing spaces into two buildings, ㄱ, ㄷ shape buildings, Single-fold type plan, Strong fence d. Southern area of Myolak mountains; Concentrating spaces into one building ㅁ shape building, Single-fold type plan with wooden floor space

To elucidate the composition of extractive nitrogenous components in the fresh Capsosiphons fulvescens cultured off the southern coast of Korea, and to determine the monthly variation of these nitrogenous components, extract samples collected monthly from December to March at Jangheung-gun, Jeonnam Province were analyzed for total nitrogen, free and combined amino acids, ATP and related compounds, betaines, trimethylamine oxide (TMAO) and trimethylamine (TMA). The content of extractive nitrogen was 1,090~1,233 mg/100 g on dry basis. The number of 21~25 ninhydrin-positive substances was detected in the analysis of free amino acids, and their total amount was 3,710~4,788 mg/100 g on dry basis. Among them, free proline, asparagine, glutamic acid, alanine, taurine and glutamine were found to be abundant. The combined amino acids amounted to 1,573~2,121 mg/100 g in total and the total amount of ATP and related compound was 33.8~84.0 mg/100 g ($1.06{\sim}2.46\;{\mu}mol/g$) on dry basis. Betaine, glycinebetaine, $\beta$-alaninebetaine, $\gamma$-butyrobetaine, homarine and trigonelline were detected in most of samples. Levels of free and combined amino acids, ATP and related compounds fluctuated from sample to sample, with their contents higher in December and January and lower in March.

Cabbage plants were transformed with the potato proteinase inhibitor II (PINII) gene, bar gene, and hpt gene using Agrobacterium. The expression of the PINII gene was driven by its own promoter which was wound-inducible. Ten transgenic plants were obtained from medium containing hygromycin as a selection antibiotic. The integration and expression of PINII and bar genes were confirmed by Southern and Northern hybridization. Growth and development of diamondback moths (Plutella xylostella) and tobacco cutworm (Spodoptera litura) larvae were examined on $T_1$ plants. The weight of the larvae and pupae of these two insects grown on transgenic plants was not different compared to those grown on wild type plants. However, the pupation and emergence rate of diamondback moths and tobacco cutworms fed on some transgenic plants was lower than on wild type plants. These results suggest that the PINII transgene under the control of a wound-induced promoter may be used for control of insects in transgenic cabbage through reduction of insect progeny number.

Purpose: The purpose of this study was to analyze the experiences of acute care hospital nurses' on spiritual care with focus group interviews. Methods: Data were collected from 24 nurses recruited from one acute-care hospital in a southern province of Korea. Six focus groups were assembled considering age and religion. All interviews were recorded and transcribed. Data were analyzed using qualitative content analysis. Results: Five categories with 14 sub-categories emerged: 1) ambiguous concept: confusing terms, an additional job; 2) assessment of spiritual care needs: looking for spiritual care needs, not recognizing spiritual care needs; 3) spiritual care practices: active spiritual care, passive spiritual care ; 4) outcomes of spiritual care: comfort of the recipient, comfort of the provider; and 5) barriers to spiritual care: fear of criticism from others, lack of education, lack of time, space constraints, and absence of a recording system. Conclusion: Participants perceived spiritual care as an uncertain concept. Some participants recognized it as a form of nursing care, and others did not. They practiced spiritual care in acute-care settings according to their personal perceptions of spiritual care. Therefore, in order to perform spiritual nursing in acute-care hospitals, it is a priority for nurses to recognize the concept of spiritual nursing accurately. It is also necessary to prepare a hospital environment suitable for the provision of spiritual care.

Objective: School nurses should be knowledgeable about attention-deficit hyperactivity disorder (ADHD) and have tolerant attitudes to children with ADHD. This study was done to identify school nurses' knowledge about, and attitudes to, ADHD. Methods: A cross-sectional descriptive correlational study was conducted. The participants were the 245 members of a school nurse association in C province in southern part of Korea. Data were collected using a self-report questionnaire. Descriptive statistics, t-test, ANOVA, and Pearson correlation coefficients were used to analyze the data. Results: Of the 245 packets mailed to members, 126 (51.4%) were returned, and of these, 122 packets (49.8%) were suitable for data analysis. School nurses in this study lack knowledge about ADHD. Moreover, school nurses reported low tolerance in their attitudes toward children with ADHD. There was no significant correlation between knowledge and attitudes in the management of ADHD among school nurses. Conclusion: Findings from this study show that school nurses have limited knowledge about ADHD and its treatment with stimulation medication. Moreover, their attitudes toward children with ADHD were in the low tolerant range. An educational program on ADHD for school nurses need to be developed and provided to facilitate the school nurses' role in assessing and caring for children with ADHD.
