  • Two strains of Cucumber mosaic virus (CMV) isolated in Kuwait were confirmed their infectivity based on symptomatology and host range on different cultivars of tomato (Lycopersicon esculentum), tobacco(Nicotiana tabacum L.) and squash (Cucurbita pepo). The pattern of symptoms differed for the two CMV strains in tomato and tobacco, showing severe stunting and mosaic symptoms with one strain designated KU2, and almost symptomless with the other strain designated KU1. A satellite RNA 5 (sat-RNA) was found to be associated with the KU1 strain and was characterized as a benign viral satellite RNA. Using reverse transcription and polymerase chain reaction (RT-PCR) with sat-RNA specific primers, an amplified PCR product of about 160bp was determined and analyzed by gel electrophoresis. This naturally occurring benign viral satellite RNA was successfully used as a biological control agent to protect tomato plants against the severe KU2 strain. Tomato plants grown in plant-growth chambers, were preinoculated with KU1 containing the benign viral satellite and then challenge inoculated with the severe KU2 strain at different time intervals. All plants challenged three weeks after preinoculation showed nearly complete protection from subsequent infection by the severe strain. This biological control technology using plant viruses was found protective and could be successfully established sooner after the preinoculation.

  • Phytoplasma was identified from leaf lettuce (Lactuca sativa) cultivated in commercial green-house in Korea. Diseased leaf lettuce revealed proliferation of shoots, and yellowing and shrinking of leaves (lettuce proliferation-K). Polymerase chain reaction (PCR) with universal primer pair P1/P6, and aster yellows (AY) specific primer pair R16F1/R1 amplified 1.5kb and 1.1kb length of DNA fragments, respectively. Nucleotide sequences of 16S rRNA gene were determined (Gen Bank accession no EF489024). Phylogenetic analysis of 16S rDNA showed the closest relationship with AY phytoplasma (GenBank accession no. AY389822 and AY389826), indicating that lettuce proliferation-K is a member of AY. Phytoplasma bodies were detected in phloem sieve tubes of diseased lettuce by transmission electron microscopy. The structures had round or pleomorphic shapes with a diameter of 130-300nm. Phylogenetic analysis of 16S rRNA gene, microscopic observation of phytoplasma bodies and symptomatology indicated that lettuce proliferation-K is caused by phytoplasma in the AY group. This is the first report of phytoplasma disease in lettuce in Korea.

  • This is a case report of invasive aspergillosis of the right maxillary antrum and the left lung in a 43 year-old male patient with diabetes mellitus and liver cirrhosis. The results were as follows. 1. Invasive aspergilliosis should be considered in compromised patients who have nasal symptomatology, infraorbital swelling and pain. 2. Invasive aspergillosis is a rapidly progressive mycotic infection of the sinus which may extend to the orbit, nasal cavity and cheek. 3. Surgical intervention is particularly urgent in orbital aspergillosis in patient in whom the eyesight is still preserved. 4. Diagnosis depends upon pathological demonstration of tissue invasion by organism with the typical morphology of aspergillus species. 5. Long-term antifungal drugs should be administrated postoperatively in pathint with invasive aspergillosis.

  • The purpose of this study was to examine the health status of the daughter and daughter- in-law caregivers who care for a cognitively and/or functionally impaired elderly, individual to identify factors that were related to reported health outcomes, and to investigate the negative and positive impacts of family caregiving. Data was collected from 120 daughter and daughter-in-law caregivers and care-recipients using face to face interviews. Most caregivers were daughters- in-law (77.5%) and most care-recipients were female (88.3%). Sixty-eight percent (n=81) of caregivers reported depressive symptomatology. General health also deteriorated by caregiving. Caregivers reported several negative impacts (difficulties): care-recipients' problematic behaviors, deterioration of their own health, pressure from social norms related to family caregiving in Korea, intrafamily conflict, and economic problems. Contrary to the popular belief, caregivers reported diverse positive impacts of family caregiving (68.3%): a sense of filial responsibilities, recognition from elderly, family members, relatives, and society, education for the children, and familial harmony. Higher depression score was predicted by lower family income, the presence of cognitive impairment of care-recipients, and higher level of social conflict of caregivers. Poor general health of caregivers was predicted by older caregivers' age, lower competing roles of caregivers, and poor emotional health. While not seeking to deny the negative aspects of family caregiving, it is also necessary to understand positive aspects of family caregiving to see complete picture of caring for an elderly family member.

  • This quantitative study was investigated to examine the relationship between severity of state-trait anxiety and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely to have an eating disorder, including anorexia nervosa and bulimia nervosa. Scores of healthy dietary behaviors were obtained by self-assessment instrument on healthy diet scale(20-item questionnaire), and severity of state-trait anxiety was calculated by state-trait anxiety inventory(Total 40- item questionnaire). In groups for each state anxiety and trait anxiety, there were divided between 50 percentile point of cumulatived scores of state anxiety and trait anxiety in all subjects. Linear regression analysis showed overall significant difference between dietary patterns(anorexia nervosa and healthy dietary behaviors) and severity of state-trait anxiety in all sex. Our results indicated that severity of state-trait anxiety may marked eating disorder symptomatology on dimensions of eating disorder prevention.

  • Due to rapid industrialization and economic development, the occupational diseases have appeared as one of the social problems in Korea. Up until now little has been known about the prevalence rate, predisposing factors and symptomatology of the occupational disease due to localized vibration in Korea. The researcher intends to investigate the prevalence rate and affecting factors of the occupational disease due to localized vibration among rock-drillers in the anthracite mines. A total of 135 rock-drillers were interviewed and examined from May 15th to 31th, 1980. The results were revealed as follows; 1. The prevalence rate of the vibration syndrome among rock-drillers was 12.6%. 2. The latent period of the vibration syndrome was 6.8 years. 3. The prevalence rate of the vibration syndrome was not significantly different between smokers and non-smokers. 4. With the increase of total vibration exposure time, the prevalence rate of the vibration syndrome increased also. 5. The average vibration sensation threshold was high (6.4dB) in stage 1 of the vibration syndrome and low (-0.6dB) in stage 0. 6. The average pain sensation threshold was high (4.4g) in stage 1 of the vibration syndrome and low (2.5g) in stage 0.

  • 성인의 우울증과는 달리 아동기 우울증의 존재와 정의에 대해서는 많은 논란이 있어왔다. DSM-III(1980)에 이르러서야 공식적인 병명으로 인정되었으나, 아직도 아동기 우울증은 다른 정신적인 장애에 비해 진단 준거 자체가 명확하게 정의되어 있지 못할 뿐만 아니라 발달 단계에 따라 우울증상은 다른 양상으로 표현되므로, 아동기 우울증의 정확한 진단을 위해서는 다양한 평가 방법을 사용하여 여러 사람들로부터 정보를 얻는 것이 매우 중요하다. 따라서 본 연구에서는 자기보고형 질문지, 면접, 행동 평정 척도, 구조화된 검사, 투사법 검사 등 주요 평가 방법들을 고찰해보았고, 앞으로 아동기 우울증 평가 방법에서 해결되어야 할 신뢰도 및 타당도에 관한 몇가지 문제점들에 대해 논의하였다.
