The purpose of this study was to investigate the relationship between self-concept and self-care activities of the cerebral palsied adolescents and to gain the baseline data for development of effective rehabilitation nursing intervention program of the cerebral palsied adolescents. The design of this study was a descriptive correlational study. The subjects of the study were 160 cerebral palsied adolescents attending at special schools located in Seoul and Kyonggi and rehabilitation centers located in Seoul, Kyonggi and Kyongnam province. The data was collected from May 20 to July 20, 2000. The instrument used for this study were the self-concept scale(50items 4point scale) and self-care activities scale(29items 4point scale). Self-Concept Scale had developed by Fitt(1965), which was standardized by Chung(1968) and modified by Kim(1984). Self-Care Activities Scale developed by the researcher through out the consulting of expert and pilot study on the basis of ADL check list developed by Kang(1984) and LDSQ-3(Lambeth Disability Screening Questionnair-3) developed by Na et al. (1995). The data was analyzed by the SPSS/PC+program using frequency, percentage, mean, standard deviation, t-test, ANOVA & Scheffe test and Pearson's correlation coefficient. The results of this study were as follows; 1. The mean score of self-concept was $138.55{\pm}17.20$(range: 50-100), which the item mean score was $2.77{\pm}0.34$(range: 1-4). The score of subarea of the self-concept was the highest score in family self ($3.01{\pm}0.54$) and the lowest score in physical self ($2.52{\pm}0.42$). 2. The mean score of self-care activities was $95.25{\pm}21.69$ (range: 29-116), which the item mean score was $3.28{\pm}0.75$ (range: 1-4). The score of subarea of the self-care activities was the highest score in feeding($3.75{\pm}0.59$) and the lowest score in walking($2.64{\pm}1.21$). 3. There were statistically significant difference in the score of self-concept according to the age (F=3.24, P=.04), the grads (F=4.36, P=.01), and types of cerebral palsy (F=2.42, P=.03). 4. There were statistically significant difference in the score of self-care activities according to the age (F=8.29, P=.00), the grads (F=16.05, P=.00), types of living place (F=6.46, P=.00), types of cerebral palsy (F=48.92, P=.00), whether or not receiving a rehabilitation therapy (t=-3.64, P=.00), whether or not receiving a vocational training (t=2.14, P=.03), and whether or not using a device (t=-7.42, P=.00). 5. There was not significant correlation between self-concept and self-care activities (r=.081, P=.311).

The purpose of this study is to explore further understanding of variables, besides father's alcoholism, which relates to psychosocial adjustment among ADAF(adult daughters of alcoholic fathers). This study examines the relationship between father's alcoholism, family functioning, parental attachment and the psychosocial adjustment among the ADAF. From a larger sample of 463 female college students, 160 ADAF and a matched group of non-ADAF were identified to participate in the study. This survey was conducted in Seoul and Gyungi-do area. Participants completed self-report questionnaires, "The Korean Version of Children of Alcoholics Screening Test", "Inventory of Parent and Peer Attachment", "Satisfaction With Life Scale", "Self-esteem", "Beck Depression Inventory" and "Family Environment Scale". Path analyses was used to test the research question. Findings indicated that father's alcoholism had no direct effect on both the psychosocial adjustment of the ADAF and the family functioning. But father's alcoholism was significantly related to parental attachment. Family functioning was significant predictor of attachment to parents as well as psychosocial adjustment. Finally family functioning is important cause for parental attachment and psychosocial adjustment, specifically self-esteem and life satisfaction outcomes only. Therefore parental attachment was function as a mediator in the relationship between family functioning and psychosocial adjustment. In conclusion, this study showed that father's alcoholism did not predict outcome. We need to reconsider the assumption that direct link exists between adult adjustment difficulties and the presence of father's alcoholism. Implications for clinical and theoretical work with ADAF are discussed.

Background: The tuberculin skin test (TST) is the standard tool to diagnose latent tuberculosis infection (LTBI) in mass screening. The aim of this study is to find an optimal cut-off point of the TST+ rate within tuberculosis (TB) contacts to predict the active TB development among adolescents in school TB outbreaks. Methods: The Korean National Health Insurance Review and Assessment database was used to identify active TB development in relation to the initial TST (cut-off, 10 mm). The 7,475 contacts in 89 schools were divided into two groups: Incident TB group (43 schools) and no incident TB group (46 schools). LTBI treatment was initiated in 607 of the 1,761 TST+ contacts. The association with active TB progression was examined at different cut-off points of the TST+ rate. Results: The mean duration of follow-up was $3.9{\pm}0.9years$. Thirty-three contacts developed active TB during the 4,504 person-years among the TST+ contacts without LTBI treatment (n=1,154). The average TST+ rate for the incident TB group (n=43) and no incident TB group (n=46) were 31.0% and 15.5%, respectively. The TST+ rate per group was related with TB progression (odds ratio [OR], 1.025; 95% confidence interval [CI], 1.001-1.050; p=0.037). Based on the TST+ rate per group, active TB was best predicted at TST+ ${\geq}$ 16% (OR, 3.11; 95% CI, 1.29-7.51; area under curve, 0.64). Conclusion: Sixteen percent of the TST+ rate per group within the same grade students can be suggested as an optimal cut-off to predict active TB development in middle and high schools TB outbreaks.

Twenty kinds of medicinal herbs were extracted by water and 95% ethanol and then antimicrobial activity of the extracts was investigated against various kinds of microorganisms. Water extracts of Gardeniae fructus (Gardenia jasminoides), Lycii fructus (Lycium chinense) and Schizandrae fructus (Schizandra chinensis) showed inhibitory effects on the growth of most of the bacteria. In the case of ethanol extracts, the 3 kinds of the samples such as Gardeniae fructus, Schizandrae fructus and Lithospermi radix (Lithospermum erythrorhizon) showed inhibitory effects on the growth of almost all bacteria. In particular, ethanol extract from Phellodendri cortex (Phellodendron amurense) showed the best inhibitory effect on the growth of S. aureus in the concentration of 0.01%. By the way, inhibitory effects of water extracts from these medicinal herbs were not so good on the growth of fungi but those of ethanol extracts were better and ethanol extracts of Phellodendri cortex showed best. Antimicrobial activity was variable according to the used extracting solvent. For example, inhibitory effets of ethanol ext-racts were $2{\sim}100$ times better than those of water extracts. Ethanol extract of Lithospermi radix was the most effective not only bactericidal effects but also sensory evaluation tests for tastes.

This study was conducted to compare the quality of the brown rice (BR) and milled rice (MR) during storage. To assess quality, BR and MR were analysed by their fat acidity and flavor pattern using a SMart Nose$^{(R)}$. BR was stored for 30 days at $30^{\circ}C$, and analysed after 5, 15, 20, and 30 days of storage. MR produced in 2005, 2009, and 2010 were also tested. The fat acidity of both rice groups was increased with extended storage and the fat acidity of BR was more rapidly increased than that of MR in general. The flavor patterns from the SMart Nose$^{(R)}$ results were analyzed by the principal component analysis (PCA). The major groups of atomic mass unit (amu) for good discrimination contribution were from 41 to 85 amus. The PCA1 and PCA2 of BR were 95.64% and 2.78%, respectively when the samples were categorized by storage period. The PCA1 and PCA2 of MR were 81.18% and 13.85%, respectively when the samples were compared by production year. Both rice groups could be practically differentiated into flavor patterns by volatile properties for storage period. With regard to the correlation between fat acidity and flavor pattern, we could find that increasing storage period increased fat acidity value and changed flavor pattern from SMart Nose$^{(R)}$. Accordingly, SMart Nose$^{(R)}$ could be successfully used for easy screening and quality evaluation of stored rice.

This study was conducted to investigate the kinds of health promotion program which workers want, worker's intention for participation, proper method, time, duration and manager. A self-administered questionnaire method was used to collect data from 412 employees of 3 worksites in Chungpook and Kyungkee. This survey was carried out from Aug. 10 to Aug. 20, 1998. The results of this study are as follows: 1. In male, among health promotion programs, favorite ones were physical fitness(32.2%), periodic health check-up(24.6%), and stress management(18.0%). In female, among health promotion programs, favorite ones were periodic health check-up(26.0%), physical fitness(22.0%), and body weight control(19.5%). 2. The more young subjects are, the more they like physical fitness program, and the female like body weight control program regardless of BMI. Manufacturing worker preferred back pain prevention program to clerical worker did. In female, drinker preferred stress management program to non-drinker did. 3. The more old subjects are, the more they like back pain prevention program, and non-smoker preferred body weight control program to smoker did. 4. In health promotion program format which the subjects wanted, learning of self-examination techniques was 41.1%, worksite screening was 3l.0%, availability of pamphlets and audiovisual materials was 20.0%, presentation of worksite educational sessions was 7.9%, and the most wanted manager for the program was medical doctor and then nurse, physical trainer, psychological counselor. The favorite health promotion program duration was less than 30 minutes(49.6%), and the favorite time was before work(49.6%). 5. Among respondents, 48.5% was smokers, 81.8% was drinkers, 39.9% engaged in the regular exercise, 68.2% engaged in regular diet habit. In vaccination, 50.2%, if possible, wanted to be vaccinated and 37.6% never wanted to be vaccinated. 6. Ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit responded they were in good health. There was a significant difference between exercise and health status. Need and intention for participation of health promotion program were high in ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit. According to results for this study, if the favorite programs, exercise, periodic health check-up, stress management program, are operated at a proper time and with managers they want, this programs can really raise the participation of employees. And as employees want to learn self-examination techniques if worksite educational sessions are performed, health promotion program can effectively be operated.

The synthesis of dimethyl carbonate(DMC) is a promising reaction for the use of naturally abundant carbon dioxide. DMC has gained considerable interest owing to its versatile chemical reactivity and unique properties such as high oxygen content, low toxicity, and excellent biodegradability. In this study, the synthesis of DMC through the transesterification of ethylene carbonate(EC) with methanol was investigated by using ionic liquid and metal oxide catalysts. The screening test of different catalysts revealed that choline hydroxide ([Choline][OH]) and 1-n-butyl-3-methyl imidazolium hydroxide([BMIm][OH]) had better catalytic performance than metal salts catalysts such as MgO, ZnO and CaO. The effects of reaction parameters such as reaction temperature, MeOH/EC mole ratio, and carbon dioxide pressure on the reactivity of [Choline][OH] catalyst were discussed. High temperature and high MeOH/EC mole ratio were favorable for high conversion of EC. However, the yield of DMC showed a maximum when carbon dioxide pressure was 1.34 MPa, and then it decreased for higher carbon dioxide pressure. Zinc chloride($ZnCl_2$) was used as co-catalyst with the ionic liquid catalyst. The mixed catalyst showed a synergy effect on the EC conversion and DMC yield probably due to the acid-base properties of the catalysts.

Recent development and enlargement of reclaimed lands along the sea shores required to explore alternatives to existing crops, which are suitable to grow well and to declare higher profits. The objectives of this study were to investigate yield-related parameters for development of new leafy vegetables, and to screen some candidates among New Zealand spinach genotypes which were collected in Korea. Initially all the collected genotypes were grown for 7 weeks in a greenhouse of the experiment field in Chungnam National University, and then transplanted into the field to measure morphological or physiological parameters (plant height, branch number, stem diameter, chlorophyll content, and maximum canopy diameter), and yield-related parameters (leaf number, leaf length, leaf width, fresh weight and dry weight). Those parameters were quantitatively measured at 1, 5 or 9 weeks after transplanting (WAT). Parameters exhibiting statistically significant difference among the accessions were plant height, branch number, maximum canopy diameter, chlorophyll content, and leaf length. In contrast to highly correlated parameters with fresh and dry weight obtained in salt-affected soil in the earlier report, fresh weight was correlated significantly with leaf length (r=0.72), leaf width (r=0.64), and canopy diameter(r=0.66), while dry weight was correlated significantly with plant height (r=0.46), leaf length (r=0.72), leaf width (r=0.73), fresh weight (r=0.79), chlorophyll content (r=0.47), and canopy diameter (r=0.87). Based on the significantly correlated with yield parameters, the candidate accessions which were ranked in top statistical groups include CNU06A01, CNU06A13, CNU06A26, CNU06A35, CNU06A38, and CNU06A55. In order to be cultivated in reclaimed lands, it is necessary to screen out salt tolerant accessions among the above high-yielding genotypes.

To understand the molecular mechanisms that regulate intramuscular fat deposition and its release, cDNA clones expressed in adipose tissues of Korean cattle were identified by differential screening from adipose tissue cDNA library. By partial nucleotide sequencing of 486 clones and a search for sequence similarity in NCBI nucleotide databases, 245 clones revealed unique clones. By a functional grouping of the clones, 14% of the clones were categorized to metabolism and enzyme-related group (stearoyl CoA desaturase, lactate dehydrogenase, fatty acid synthase, ATP citrate lyase, lipoprotein lipase, acetyl CoA synthetase, etc), and 6% to signal transduction/cell cycle-related group (C/EBP, cAMP-regulated phosphoprotein, calmodulin, cyclin G1, cyclin H, etc), and 4% to cytoskeleton and extracellular matrix components (vimentin, ankyrin 2, gelosin, syntenin, talin, prefoldin 5). The obtained 245 clones will be useful to study lipid metabolism and signal transduction pathway in adipose tissues and to study obesity in human. Some clones were subjected to full-sequencing containing open reading frame. The cDNA clone of bovine homolog of human prefoldin 5 gene had a total length of 959 nucleotides coding for 139 amino acids. Comparison of the deduced amino acid sequences of bovine prefoldin 5 with those of human and mouse showed over 95% identity. The cDNA clone of bovine homolog of human ubiquitin-like/S30 ribosomal fusion protein gene had a total length of 484 nucleotides coding for 133 amino acids. Comparison of the deduced amino acid sequences of bovine ubiquitin-like/S30 ribosomal fusion protein gene with those of human, rat and mouse showed over 97% identity. The cDNA clone of bovine homolog of human proteolipid protein 2 mRNA had a total length of 928 nucleotides coding for 152 amino acids. Comparison of the deduced amino acid sequences of bovine proteolipid protein 2 with those of human and mouse showed 87.5% similarity. The cDNA clone of bovine homolog of rat thymosin beta 4 had a total length of 602 nucleotides coding for 44 amino acids. Comparison of the deduced amino acid sequences of bovine thymosin beta 4 gene with those of human, mouse and rat showed 93.1% similarity. The cDNA clone of bovine homolog of human myotrophin mRNA had a total length of 790 nucleotides coding for 118 amino acids. Comparison of the deduced amino acid sequences of bovine myotrophin gene with those of human, mouse and rat showed 83.9% similarity. The functional role of these clones in adipose tissues needs to be established.

Pheromones of several insect species were evaluated in a screening program in terms of their usefulness in pest forecasting and control in Korea. Species included striped rite borer (Chilo suppressalis) and tortricid moths, which attack deciduous fruit, and colding moth. The pheromone of striped rice borer was supplied through the courtesy of the Tropical Products Institute, London. Pheromones of other species were obtained from Cornell University and the Zoecon Corporation of Palo Alto, California. 'rho results of this experiment were as follows: 1. Live traps containing virgin striped rice borer female moths were more effective in attracting male moths than were the pheromone traps. 2. Since the effectiveness of the striped rice borer pheromone decreased dramatically with time, it was difficult to estimate the peak tine of the borer emergence. 3. The primary species trapped in deciduous fruit orchards was the oriental fruit moth, Grapholitha molesta. The traps were baited with the phermones, OFM and LAW. 4. Several moth species were trapped with OBLR. RBLR. SPAR and ArcM phermones but few were trapped with the remaining eight tortricid pheromones. 5. The following tortricid pheromones might be useful for forecasting the species given: OFM, LAW : Grapholitha molesta OBLR : Archips breviprecanus OBLH, RBLR, ArcM : Archippus coreensis Archips fuscocupreanus Hoshinoa longicellana SPAR, TBM ; Phyroderces sp.
