  • Resin flow, symptom development, and lignin biosynthesis in response to wounding and fungal inoculation were investigated in Pinus rigida and Pinus densiflora. The two-year-old seedling stems were subjected to three types of treatments: (i) wounding without inoculation, (ii) wound-inoculation with a conidial suspension of Fusarium circinatum, and (iii) pre-wounding woundinoculation with the fungus 20 days after the initial wounding. Resin flow from wounding sites was more evident in P. rigida than P. densiflora in all treatments. The wound-inoculation with the fungus induced almost two-fold higher levels of resin flow than the other treatments in both species. The pre-wounding woundinoculation appeared to result in a decrease in pitch canker development in the two pine species. Some reductions in disease severity were observed in the prewounding wound-inoculated P. rigida, showing a mean disease severity of less than 85%, compared with approximately 100% in the wound-inoculated stems. Disease severity was approximately 50% in the woundinoculated P. densiflora, whereas 10% in the pre-wounding wound-inoculated stems. Higher amounts of lignin were found from bark (ca. 40%) than from xylem (ca. 30%). The wound-inoculated bark and the pre-wounding wound-inoculated bark exhibited higher amounts of lignin among the other treatments. These results suggest that the wound-inoculation apparently prompt the increase in resin flow and lignin biosynthesis from the two pine species, and the prior wounding may be involved in decreased disease severity against the further invasion of F. circinatum.

  • This study was to investigate the relationship of VDT(visual display terminal) work condition and fatigue severity in the financial office workers. Questionnaires were completed by 662 persons in VDT workers of Post Office from January to May 2006. Multidimensional Fatigue Scale(MFS) that was developed in Korea Occupational Safety &Health Agency to estimate the degree of fatigue was used for study. In results, 149 persons(22.5%) in VDT workers were felt low fatigue severity, 351 workers(53.0%) were middle, and 162 workers (24.5%) were high. So it was appeared that one in four VDT workers felt the high fatigue severity. And woman VDT workers felt more fatigue severity than man. Also, fatigue severity was increased with increasing work time. Our findings suggest that VDT workers in financial office need proper health program to prevent occupational fatigue and disease.

  • Purpose : The purpose of this study is to identify the difference of clinical effects of gyejibongnyeong-hwan and acupuncture therapy on primary dysmenorrhea. Methods : We studied with ten patients recruited from April, 2003 to Feburary, 2004. Women with organic disease as uterine myoma, ovarian cysts and pelvic inflammatory disease were excluded from this study. We treated them with gyejibongnyeong-hwan or gyejibongnyeong-hwan combined acupuncture therapy for 8weeks. The severity of dysmenorrhea was measured by VAS(Visual Analog Scale). Results : gyejibongnyeong-hwan significantly decreased the severity of dysmenorrhea. And Gyejibongnyeong-hwan combined Acupuncture therapy significantly decreased the severity of dysmenorrhea. The change of VAS of gyejibongnyeong-hwan group is significantly higher than gyejibongnyeong-hwan combined acupuncture. Both of Gyejibongnyeong-hwan and acupuncture did not show hepatic and renal virulence. Conclusion : This study shows that gyejibongnyeong-hwan has remarkable effects on dysmenorrhea patients. Obviously further researches concerning all these area still necessary.

  • Background: Inflammatory diseases can increase the prevalence of anemia. Recent studies confirmed that the prevalence of anemia is increased by atopic dermatitis (AD), a chronic inflammatory disease. Therefore, we aimed to elucidate the correlation between AD severity and prevalence of anemia. Methods: We used data of pediatric patients from the Health Insurance Review and Assessment Service (HIRA-PPS-2016). We included pediatric patients (<18 years) with AD diagnosis who were prescribed medications for AD. We applied a propensity score method with inverse probability of treatment weighting (IPTW) adjusting for differences in prevalence of confounders and performed IPTW logistic regression to evaluate associations between the anemia and severity of AD. Results: In total, 91,501 patients (mild AD: 47,054 patients; moderate-to-severe AD: 44,447 patients) <18 years who were prescribed drugs for AD were analyzed. Analysis of the probability of patients with mild AD and prevalence of anemia as a reference revealed an odds ratio (OR) of 1.159 (95% CI, 1.109-1.212; p<0.001) in moderate-to-severe AD patients, indicating a correlation between anemia prevalence and AD severity. Subgroup analysis according to gender, age group, and type of health insurance revealed there was an association between AD severity and anemia except in patients equal or older than 7 years. Conclusion: The prevalence of anemia increased with AD severity despite adjusting for confounding factors. Our results support the hypothesis that AD can cause anemia, and anemia prevalence could be increased in severe AD patients. Further studies are needed to establish a pathological basis.

  • 오이 흰가루병(Sphaerotheca fusca)이 수량에 미치는 영향을 구명하고자 오이 잎 제거를 통한 시뮬레이션으로 적정 잎수에 관한 모의시험 및 발병도 조절에 따른 흰가루병이 수량에 미치는 영향과 경제적 피해허용수준을 검토하였다. 오이 잎 제거 수준과 수량과의 시뮬레이션 결과 봄작기에서는 오이 잎 수를 10매, 가을작기에서는 13매 정도를 유지하면 표준방제구와 큰 차이가 없었다. 오이 흰가루병 발병도가 증가할수록 수량이 감소하였으며, 특히 상품성 수량의 감소폭이 전체 수량의 감소폭보다 더 커서 상품성 수량에 큰 영향을 미쳤다. 오이 흰가루병 발병도와 수량과의 회귀식은 Y=-57.237x+6143.1, $R^2=0.9628$로 방제비용을 감안하여 수량 3% 지점의 발병도 17.6%를 경제적 피해 허용 수준으로 설정하였다. 오이 흰가루병 방제적기는 경제적 피해 허용수준과 시뮬레이션 결과를 종합할 때 흰가루병으로 발병된 잎이 $1{\sim}2$장일 때 방제를 시작해야 하는 시점으로 생각된다.
