This research was undertaken to examine Masan's regional food service industry, which experienced drastic changes due to liberation and the Korean war. Analysis of restaurant advertisements in 'Masanilbo' revealed a total of 92 restaurants during this period. The numbers of restaurants classified by the time periods are 18 (1946 to 1950), 27 (1951 to 1955), 17 (1956 to 1960), and 30 (1961 to 1966). 'Gomguk' gained popularity in the early 1900s and became a speciality of Masan, resulting in the appearance of numerous Gomguk restaurant advertisements. After independence, Japanese foods were predominant in Masan since the population was used to eating Japanese dishes during the colonial era. Moreover, there was a major influence of the people who returned to the homeland. Masan was the place for refugees during the 6.25 war, resulting in the popularity of 'Naengmyeon'; advertisements largely displayed 'Pyeongyangnaengmyeon' during the early 1950s, and 'Hamheungnaengmyeon' during the early 1960s. Western food advertisements usually introduced 'Dongaseu' and 'Kareraiseu', which were deeply influenced by Japanese culture. These various contributions resulted in alterations in the food menu, such as the rise of fusion food which is not bound to any nation, spread of Japanese food culture, and popularity of 'Naengmyeon'.

본 논문은 토지대장과 지적도를 이용하여 일제강점기 동안 광주의 금남로 지역을 대상으로 토지 이용의 변화, 가로형태의 변화, 토지소유의 사회적 패턴의 변화를 고찰하였다. 일제시대 광주의 대표적인 상징물인 전남도청과 광주역을 연결하는 직선 상징 축으로서 금남로는 1925년에 시작되어 1933년에 완성되었다. 금남로 지역은 밭과 논이 있었으나 1940년에 모두 대지화되었다. 광주읍성내는 일본인과 국가의 토지소유가 많았고, 읍성 밖은 한국인의 토지소유가 많았다. 금남로의 개설이 금남로 1 2 3 4 5가의 토지소유의 사회적 패턴의 변화에 큰 영향을 미치지는 못하였지만, 금남로 5가의 밭의 대지로의 전환에는 약간의 영향을 미쳤다고 할 수 있다. 금남로 지역의 토지이음의 변화에는 금남로의 개설보다는 광주의 인구증가 등 도시화에 의한 영향이 더 크게 작용하였다고 할 수 있다.

Background: The incidence of bladder cancer is lower in Asian than in Western countries. However, the crude incidence and mortality of bladder cancer have recently increased in Japan because of the increased number of senior citizens. We have already reported risk factors for urothelial cancer in a large population-based cohort study in Japan (JACC study). However, we did not evaluate the cancer risk in the upper and lower urinary tract separately in our previous study. Materials and Methods: Here we evaluated the risk of cancer death in the upper and lower urinary tracts, separately, using the database of the JACC study. The analytic cohort included 46,395 males and 64,190 females aged 40 to 79 years old. The Cox proportional hazard model was used to determine hazard ratios and their 95% confidence intervals. Results: Current smoking increased the risk of both upper and lower urinary tract cancer deaths. A history of kidney disease was associated with an increased risk of bladder cancer death, even after controlling for age, sex and smoking status. Conclusions: The present study confirmed that current smoking increases the risk of both upper and lower urinary tract cancer deaths and indicated the possibility that a history of kidney disease may be a risk factor for bladder cancer death in the Japanese population.

본 연구는 2006년 8월경에 어획된 서해, 남해 및 동해 멸치집단을 분석하기 위하여 6종류의 microsatellite로 하였다. 서해멸치의 경우, 샘플수 72마리에 대한 allele 범위가 19-41로 평균 28.5를 보였다. 특히 EJ9 locus에서 평균보다 약 1.4배 많은 41를 나타내었다. 남해멸치의 평균 allele는 24.5로 서해보다는 적었고, EJ2, EJ9, EJ27.1 loci는 평균보다 높은 29-37의 범위를 보였다. 동해멸치는 평균 allele가 25.0으로 EJ35를 제외하면 대부분의 loci에서 평균 이상을 보였다. 그러나 서해, 남해 및 동해멸치의 allele 빈도율은 대부분 0.24 이하로 나타났다. 또한 Hobs보다 Hexp에서 0.5 정도 높은 값을 보였으나 유의성은 없었다(p>0.05). 유전적 다양성도 0.9 이상으로 매우 높은 값을 보였다. 6종류의 microsatellite에 대한 지역간의 유전적 차이 및 거리는 0.258과 0.019로 유의적으로 차이는 없었다 (p>0.05). 따라서 서해, 남해 및 동해 멸치계군은 유전적으로 동일한 집단을 형성하고 있는 것으로 판단된다.

The effect of breeding length of sire on genetic progress was examined in the Holstein dairy cattle population in Japan. Genetic progress was extimated by gene flow method. Breeding length of sires directly influences the replacement rates of sires and the selection intensity of sires because there are a fixed number of progeny tested young bulls per year. As breeding length of sires increased, rate of gene flow decreased and average proportions of genes deriving from selected animals had lower asymptotic values. When breeding length was short, average proportions of genes required a longer period to converge to asymptotic values. Changes of Rcow-sire's(sire to breed recorded cows) and Ncow-sire's(sire to breed non recorded cows) breeding length influenced not only transmission of their genes but also that of genes derived from all other selected animals. Irrespective of whether the discount rate was assumed to be 0 or 6%, longer term (${\geq}$ 20 years) expected total genetic improvement was maximized by a sire breeding length of five years. For shorter term assessment(10 years), genetic improvement was maximized by a sire breeding length of three years. There was a linear increase in the contribution of the sire to bulls pathway to the total genetic improvement, with increase in the term of assessment.

The distribution and form of pine wood nematode (PWN) were investigated in Jinju-si and Sacheon-si areas, where infested with pine wilt disease (PWD). The average PWN population per g of the tubulation part in the wilted Japanese balck pine were 381.2 and 341 in Jinju-si and Sacheon-si, respectively. The PWN population per g of affected Japanese black pine with wilt rate below 60% were 556 and 518 in Jinju-si and Sacheon-si, respectively. The ratios of PWN and other plant-parasitic nematode in the wilted Japanse black pines were 48% vs. 52% in Jinju-si and 53% vs. 47% in Sacheon-si after exposure to PWD for 1 year. The survivorship of pine wood nematode in the sampled trees after 1 year was 0-10% in the Jinju-si area and 5-20% detected in the Sacheon-si area. In the forest areas affected by PWN, the highest survival rates were 37.2% and 39.8% at 25 cm diameter at breast height (DBH) in Jinju-si and Sacehon-si, respectively, while the highest wilt rates were 30.5% and 28.3% at 30 cm DBH in Jinju-si and Sacehon-si, respectively.

We examined Y chromosomal DNA polymorphisms at the DYS19 and DXYS5Y loci in a total of 480 unrelated male samples from the Korean population. All five common alleles were identified at the tetranucleotide microsatellite locus DYS19 in this study. The C allele was the most frequent (212/480), followed by D (136/480), B (75/480), E (36/480) and A (21/480) allele. The frequency of Y2 allele at the DXYS5Y locus was found to be 4.6% (22/480). Combining the allelic variation at these two loci resulted in a total of 9 combination haplotypes. The mean combination haplotype diversity wIns 0.72. Based on the results of these two loci, Korean and Japanese populations may share some common genetic structure that is rare or absent in the other ethnic groups. The genetic similarity between Korean and Japanese populations may be due to the large infusion of Y chromosomes through the Yayoi migration starting 2,300 years ago from Korea to Japan.

Microsatellite market는 유전연관분석을 위한 매우 유용한 유전표지이다. 그러나 대부분의 market들은 서양인의 정보를 이응하고 있으므로 다른 종족에서 사용할 때는 종족간에 존재할 수 있는 유전 변이의 현저한 차이를 검증해야 한다. 한국인과 일본인 집단에서 종족간 유전 변이를 조사하기 위하여, 각각 96명의 비 혈연관계의 한국인과 일본인 개체들에서 DNA를 채취하였다 그리고 microsatellite set(ABI PRISM Linkage Mapping Set- HDS, Applied Biosystems, Foster City, CA, USA)을 이용하여 1번 인간 염색체 전 부위에 걸쳐 51개의 microsatellite marker들을 배열하고 부착된 marker들의 위치를 분석하여 대립유전자 빈도와 이형질성을 결정하였다 그 결과, 한국인과 서양인 집단 사이에는 현저한 차이를 보였으나 한국인과 일본인 집단 사이에서는 매우 유사하였다. 본 연구의 결과는 유전 연관 연구에 앞서 일반적으로 상용되는 microsatellite marker에 관한 광범위한 검증을 반드시 시행하여야 한다는 것을 나타낸다. 또한 한국인과 일본인 집단 사이에서 유사하게 나타난 대립유전자 빈도와 이 형질성은 두 민족간의 동질성이 높다는 것을 의미하므로 두 민족을 대상으로 한 1번 인간염색체와 관련된 유전 질환의 유전 연관 연구를 시행할 때 동일한 microsatellite marker의 이용 가능성을 제시하였다.

The history of occupational health in Korea s covered the era of the Republic of Korea after the Liberation from the Japanese colonialism. But the number of Korean workers exceeded about 2 millions at the times of liberation in 1945, so that it is expected that many occupational health problems inflicted Korean workers under the Japanese colonialism. The authors reviewed medical literatures, administrative documents, and other available data which were published under the colonial state, and collected things which had reference to the health status of Korean workers. The results were as follows : 1. Nutritional status of Korean workers was supposed to be inferior to that of general population, some students, and poor inhabitants in a remote mountain villages. 2. It was supposed that the constitution of Korean workers was near lower limit of average build of contemporary Koreans. 3. The accidents rate in mines was significantly high but decreasing year after year, and the most important cause of accidents was the fall of roof in the mine. The medical facilities and equipments for miners were supposed to be not sufficient in the mines and workshops. 4. Some occupational disease including silicosis, noise-induced hearing impairment, and decompression disease were known. But, overall incidence or prevalence of these diseases could not be identified. 5. On the whole, the fatalities of acute infectious diseases of Korean workers were higher than those of Japanese inhabitants in Korea and Korean inhabitants. The prevalence of pulmonary tuberculosis of Korean workers was increasing with every passing year. 6. The medical personnels and facilities were so deficient that most Korean workers were out of adequate medical use. We discussed only a part of the health status of Korean workers under the Japanese colonialism, so it would be necessary to have a better grasp of details of occupational health policy and health status in the era of afflicting.
