Recently, the Specified streets are designated in the many cities. The specified street is formed naturally by gathering the same type of shops in the same street. The purpose of the specified street is to enhance and to make more lively the characteristics of the street. These specified street has the network consisted of elements, namely shop owner, the authorities, the consumers, etc. In the beginning, we examined how specific streets are made and composed in Seoul and Inchun: the street of the culture, the rodeo, and the furniture. As it turned out, the formation of the network organization in the specific streets showed that how much it is important that it impacted managing. The members of network work together for improvement of the street by negotiation and cooperation. In that process, the street scenery is also improved. This network promotes the spontaneous participation of the members of the affair. In the result of that, the effect of the network is a core which is one of the factors managing and improving specific street. A continuous examination of the more study would strengthen the importance of the network in changing specific street construction.

大邱市內에 있어서의 山羊 및 緬羊의 結核症에 對한 調査

Tuberculosis is rare in sheep and goats. In sheep most of the infection that have been typed in the United States were found to be of the avian-type, but in orther countries most have proved to be of the bovine-type. The data on tuberculosis in goats are very meager, so this fact gives an impression on us that goats are relatively resistant to infection. Infections, however, with human-type, bovine-type and aviane-type have been rarely reported. The obtained specimens (lung, liver, spleen) from a died goat at Taegu Agriculture and Forestry High school in March 1960 were examined bacteriologically and pathologically to diagnose the cause of its death. Moreover, the 10 sheep and 13 goats which had been together in the same pen with the died goat and the 11 sheep and 202 goats which had been fed in the surrounding area of Taegu city were tested on the tuberculin reaction with the intradermal method. The tuberculin was mamalian type (O.T.). The results thus obtained would be outlined as follows: 1. The death of the goat at above school was caused with a generalized tuberculosis infected through respiratory route by the bovine-type of tubercle bacilli. 2. The result of tuberculin test have proved that among 10 sheep and 13 goats which were fed together with the died goat, the positive reaction was found in 2 sheep (20%) and 2 goats (about 15.4%) and the doubtful reaction was found in 1 sheep (10%) and 2 goats (about 15.4%), but among 11 sheep and 202 goats which were fed in the surrounding area of Taegu city, the positive and doubtful reaction were found in 2 goats (about 1%) and 3 goats (about 1.5%) respectively, and all of the sheep reacted in the negative.

Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

The effect of the phases of y, α' and ε martensites, which constitute the structure of the 316L stainless steel with austenite structure at room temperature, on the damping capacity at room temperature has been investigated. As a result, various fractions of these phases were formed depending on the degree of cold work. The largest volume fraction of a martensite phase is obtained by 20% cold rolling and showed the highest damping capacity. The damping capacity is strongly controlled by the volume fraction of ε martensite with linear relationship, while the other phases of α' and r have actually no effect on the damping capacity.

목적: 이 연구는 뇌 · 심혈관 질환으로 업무상재해를 신청한 사례 중에서 승인된 사례와 불승인된 사례의 특성을 비교하여 뇌 · 심혈관 질환의 업무상 재해여부를 판단하는데 필요한 기초 자료를 제공하고자 한다. 방법: 2000년부터 2004년까지 근로복지공단에 업무상 재해로 요양이 신청되어 승인여부가 결정된 뇌 · 심혈관 질환자 12,309명을 대상으로 하였다. 승인여부와 관련된 특성을 확인하기 위해 연도별, 업종별, 규모별, 직업별, 성별, 연령별, 질환별, 생존유무별 그리고 기존질환 유무에 대하여 카이제곱 검정과 다변량 로지스틱 회귀분석을 이용하였다. 결과: 다변량 로지스틱 분석에서 뇌 · 심혈관 질환의 불승인에 대한 승인의 비차비는 광업을 기준으로 하였을 때에 전기가스 상수도업이 4.18(95% CI=1.43~12.17), 건설업이 2.39 (95% CI=1.22~4.69), 제조업이 2.10 (95% CI=1.08~4.07)이었고, 장치기계조작원 및 조립원에 비하여 서비스 근로자 및 상점과 시장 판매근로자 군이 1.90(95% CI=1.47~2.47), 전문가 군이 1.83(95% CI=1.50~2.23), 기술공 및 준전문가 군이 1.63(95% CI=1.35~1.97), 입법 공무원과 고위 임직원 및 관리자 군이 1.62(95% CI=1.24~2.12)이었고, 여성이 남성에 비하여 1.31(95% CI=1.13~1.53), 심장질환에 비하여 뇌혈관질환이 2.75(95% CI=2.42~3.13), 사망한 경우가 생존한 경우에 비하여 6.01(95% CI=4.89~7.38)이었다. 결론: 우리나라에서 뇌심혈관질환으로 업무상 재해를 신청하는 건수는 증가하고 있고 승인율은 비교적 높았으며 승인에 영향을 미치는 요인으로는 업종, 규모, 직종, 성, 연령, 질환, 생존유무 등이 확인되었다. 특히 업종과 직종에 따라서 승인율의 차이가 큰 것이 어떠한 요인의 영향 때문인지에 대한 검토가 필요하고, 특히 뇌실질내 출혈의 경우에 다른 질환에 비하여 승인율이 매우 높았던 것은 업무수행성에 대한 인정기준의 잘못된 적용의 결과 이므로 시정이 필요하겠다. Objectives: This study was performed to provide fundamental data to judge whether or not cerebro and cardiovascular diseases are work-related, by comparing the characteristics between approved and non-approved cases among the worker's compensation claims. Methods: We collected 12,309 cerebro and cardiovascular disease claims based on the worker's compensation records of the Labor Welfare Corporation from 2000 to 2004. The approved and non-approved cases were analyzed according to factors such as the calendar year, industry, company size, occupation, gender, age group, classification of cerebro and cardiovascular diseases, fatality and underlying diseases. We used x²-test and multivariate logistic regression for the analysis. Results: According to multivariate logistic regression, electricity gas and water supply (OR=4.18, 95% CI=1.43~12.17), construction (OR=2.39, 95% CI=1.22~4.69) and manufacturing (OR=2.10, 95% CI=1.08~4.07) industries had a higher approval rate than mining and quarrying industries. Service workers and sales & marketing department workers (OR=1.90, 95% CI=1.47~2.47), professionals (OR=1.83, 95% CI=1.50~2.23), technicians and associate professionals (OR=1.63, 95% CI=1.35~1.97) and legislators and senior officials and managers (OR=l.62, 95% CI=1.24~2.12) had a higher approval rate than plant and machine operators and assemblers. Female workers had a higher approval rate (OR=1.31, 95% CI=1.13~1.53) than male workers. Cerebrovascular diseases had a higher approval rate (OR=2.75, 95% CI=2.42~3.13) than cardiovascular diseases. Fatal cases had a higher approval rate (OR=6.01, 95% CI=4.89~7.38) than surviving cases. Conclusion: For cerebro and cardiovascular diseases, workers' compensation claims are increasing, approval rates are relatively high and factors such as industry, company size, occupation, gender and fatality are related. A remarkable difference in the approval rate was found according to industry and occupation, suggesting the need for further study to identify which factors influence the approval rate. The approval rate for intracerebral hemorrhage arising in the course of employment (COE) was significantly higher than that arising out of employment (AOE), suggesting the need to correct the approval criteria.

This experiment was conducted to study the influence of environment cultural method and their interaction on the growth and yield components of flue-cured tobacco. Applied variety was NC 2326, and was treated by sowing time(Mar. 11, Mar. 21 and Mar.31), seedling age (40,50 and 60 day) and soil moisture stress period (20 days from 10, 20 and 30 days after setting). The results are summarized as follows. 1.During growing period, stem height, length and width of the largest leaf and total leaves were affected remarkably by the treatments. 2.Soil moisture stress period affected more the characters of tobacco plants than other factors. 3.The tobacco plant treated by early stage soil moisture stress (period from 10 to 30 days after setting) made the early growth very poor, and that tobacco plant showed poor growth until 45 to 50 days after setting. 4.Early sowing, 40 day seedling and early stage soil moisture stress made the plant type sylindrical, and late sowing and 50 to 60 day seedling made the plant type cone shape. 5.Number of total leaves and harvested leaves, leaf area per plant percentage of dry matter of leaf and specific leaf weight decreased by the treatment of soil moisture stress during early and middle part of maximum growth stage. 6.There were little differences of yield among the treatment of different sowing time and seedling age. Early sowing increased the thickness of leaf and weight per unit leaf area, and decreased number of total leaves and specific leaf weight. Number of total and harvested leaves and specific leaf weight of cured leaves were high in the plot of 60-day seedling 40-day seedling showed heavy weight of unit leaf area and low specific leaf weight of cured leaves. 7.From the point of view of interaction between sowing time and seedling age, early sowing (Mar. 11) with 60-day seedling, middle sowing (Mar. 21) with 50-day seedling and late sowing (Mar. 31) with 40-day seedling are recommended. 8.Rapid growth of early growing stage was shown in the plot of adequate soil moisture and late sowing (Mar. 31) with 50-day to 60-day seedling. 9.From the point of standard quality of cured leaves, sowing time can be shifted until late March. And to fix the sowing time, It should be considered that the maximum growth stage and the harvesting time of cutter and leaf would not match with severe drought of May and rainy season of early summer respectively.

This experiment was carried out to obtain indispensable information to establish comprehensive cultural method of rice in direct seeding on dry paddy at Chungbuk Agricultural Research and Extension Services. Effect of seeding date on dry matter production, yield components and yield were studied. Seeding on May 5 ensured the highest maximum number of tillers, while transplanting on May 20 gave the highest rate of effective tillers. Number of effective tillers was greater in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. Lengths of upper three leaves were increased at later seeding, but leaf width was not affected by seeding date. Ratio of leaf blade weight was higher in earlier seeding during 30 days before heading but was higher in later seeding during 30 days after seeding, and was higher in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. CGR, RGR and NAR were not significantly different among seeding dates during 30 days before heading, but were lower in later seeding during 30 days after seeding. LAR was not affected by seeding date during 30 days before heading, but was higher at seeding on May 5 in heading date and during 30 days after heading. Dry weight of leaf blade, leaf sheath and culm, ear and total biomass during 30 days before heading and heading were highest in May 5 seeding. Daekwanbyeo and Hwaseongbyeo in May 5 seeding and Hwajinbyeo in April 20 seeding brought the highest yield with greater number of spikelets, higher ripening ratio and greater 1,000 grain weight, and harvest index and grain/straw ratio were Increased at earlier seeding. There were significantly positive correlations between number of panicles per m2 and LAI at 30 days before heading and heading, dry matter weight of leaf blade and total mass at heading. On the other hand, there were significantly negative correlations between seeding date and ripened grain ratio. 1,000 grain weight and yield, and between 1,000 grain weight and leaf length of 2nd, respectively.
