  • This study aims at analyzing the potential of leports-fishing for improving fishing household income. Leports-fishing is a composite concept which is combined with those of leisure, sports and fishing. Korean on-shore resources have also a composite characteristic. The characteristics of the east, west and south coastal waters are quite different in geography, biology and ecology. There is a array of leports-fishing development potentials of utilizing their characteristics. At present, angling forms a main activity of leports-fishing, but coastal seas would be an emerging space for the public. In order for them to be a ground of fun, enjoyment and festivals, there would be necessary to supply a wide range of activities including angling, scuba diving, fish barbecue, ecological experience, fishing experience, cruise, and so forth. As seen in the survey results, the participants have strong desire for fun and enjoyment through leports-fishing activities. The proportion of people participating in one or two times a year amounts to 40 percent. Most coastal places visited are close to medium/large cities and two-days leports-fishing/ tourism accounts for some 77 percent. However, it is shown that conflicts between leports-fishing participants and fishermen are not serious. The results of expenditure function estimation appear that the elasticity of per capita income is very high with 1.2660 and that there are negative relationships between leports-fishing expenditure and transportation/food/lodging costs. Assuming the economic growth rate of 4 percent, it is anticipated that Korean leports-fishing population will increase to 3.18 million in 2010 and 4.07 million in 2015. Korean leports-fishing market potential in 2015, which is calculated based on per capita expenditure on leports-fishing appeared to be 1,400 billion won$\sim$1,600 billion won. The contribution of such market potential is expected to be 62.3$\sim$74.2 percent(934.5 billion won$\sim$111.3 billion won) to the fishing households.

  • Background: Family planning is widely practiced today to resolve the over-growing population and overcome obstacles that thwart socio-economic growth. While Ghana was the first country in Africa to implement family planning program, its birthrate is still twice as much as world average due to weak infrastructure and strategic plans to enforce the policy. Thus, there is a need to objectively verify the factors that affect family planning of fertile women of Ghana. Methods: Total of 630 self-administered questionnaires were distributed from April 8 to 17 of 2013 to collect data. Six-hundred eighteen questionnaires were analyzed, excluding the 12 incomplete questionnaires. Collected data were analyzed using PASW SPSS ver. 18, and logistic regression analysis was performed to verify the factors that affect practice of family planning. Results: Satisfaction with health and medical facilities, experience with family planning education and awareness of birth control methods significantly affected practice of family planning. Based on analysis using odds ratio, enforcement rate of family planning increased by 4.574 times when the subjects were satisfied with health and medical facilities, by 3.920 times when received family planning education, and by 3.284 times when they were aware of birth control methods. Conclusion: By adopting family planning education program, government should be able to change fertile women's perception of family planning. A strategic plan is necessary in order to increase access to medical facilities, improve service satisfaction, and induce women to enforce family planning voluntarily.

  • Recently, some researches related to air pollution problems in large cities of the Islamic Republic of Iran have been done. Famous institutes and research centers in countries like Japan, Sweden and Germany have been in cooperation with Iranian institutes in implementing the results. Due to quick increase in the population because of peoples' migration from countryside to cities, and rate of growth in the early years after the revolution, air pollution was an important problem in I.R.Iran. Therefore, air pollution control is one of the main issues in major cities of I.R. Iran. It is the purpose of this study to investigate the control mechanisms for air pollution problems in the major industrial cities. The necessary action plans that were taken in recent years in some of the cities, which were also suggested to be taken in the other ones, are the other purpose of this study. From the results of studies it was obtained in Iran, lots of researches are important to mention. Amongst the main activities that are done in recent years are: establishing of the meteorological research centers and atmosphere sciences; three applicator meteorological research centers and more than 40 new stations in the country; installation of newest computer systems in metrological information, using of wall map and continuous radio-traffic to announce traffic news; completing of subway construction in Tehran; forbidding of industrial activities in a definite distance away from Tehran and transferring them to suitable places; building of highways and freeways; improving of public transportation and gasifying them; developing of fuels quality and removing lead from them; and gasifying of the heating systems in houses and buildings.

  • The position effects on the abortion of flowers, fruits, and ovules were examined in relation to the resource limitation hypothesis using a temperate legume species, Vicia cracca. Fifty plants were randomly sampled from a natural population located at the Belmont Conservation Site in Belmont, MA, USA. Due to indeterminant growth and acropetal flowering of this species, the position of flower or fruit on the plant was able to be coded by the combination of architectural levels such as plant half (lower and upper half) and inflorescence half (lower and upper half) within each plant half. Overall, only 17.3% of the flowers on an inflorescence began to develop into fruits, while overall 36.0% of the fruits initiated failed to mature. Consequently, 11.5% of the flowers successfully matured into fruits. The mean flower number per inflorescence differed significantly among plants as well as between plant halves. Although the probability of fruit initiation was higher in the lower halves of both plant and inflorescence than in the upper halves of the latter, fruit abortion rate differed significantly only between plant halves. The overall mean seed set was 33.6%, implying that about two out of six ovules in a fruit matured into seeds. The seed set was independent of both plant identity and architectural level unlike other reproductive characters examined. When the ovule developmental stage was examined on data pooled over all fruits, the proportion of ovules in varying developmental stages decreased in order of early abortion, seed maturation, late abortion, and seed predation (48.4, 34.9, 12.2, and 4.5%, respectively). A within-fruit ovule position was also used as a class variable for the analysis of position effects on ovule development. All architectural levels considered exerted singificant influence over the ovule development. In particular, ovule development was strongly affected by the within-fruit ovule position. Ovules in both extreme ends within a fruit tended to abort early, while those in the middle position were more likely to mature into seeds. The strong position effects detected from the flowering to seed maturation stage were interpreted as an indication of competitive interaction among reproductive characters which are largely constrained by plant architecture.

  • 베트남의 경제 성장률과 도시인구는 꾸준히 증가함에 따라 베트남의 인프라 개발 건설 시장 규모는 더욱 커질 전망이다. 그러나 인프라 개발을 위한 베트남 정부는 재정 및 행정 능력의 한계로 이러한 문제를 해결하기 위한 방안으로 PPP를 채택하고 있다. PPP는 10년 이상 지속되는 장기 사업으로 사업 실패 시 장기적 큰 피해가 될 수 있어 위험관리가 매우 중요하다. 본 연구에서는 리스크 관리에 대한 리스크 요인의 영향과 관리정도 분석에 SOM분석을 제안한다. SOM분석 방법은 시각화 분석으로, 각 리스크 요인의 색상 패턴을 통해 상관 분석이 가능하다. 본 연구는 SOM을 활용하여 베트남 PPP 사업의 위험요인의 우선순위를 결정하고자 한다.

  • Objective: The I pig is a long nurtured longstanding breed in Vietnam, and contains excellent indigenous genetic resources. However, after 1970s, I pig breeds have become a small population because of decreasing farming areas and increasing pressure from foreign breeds with a high growth rate. Thus, there is now the risk of the disappearance of the I pigs breed. The aim of this study was to focus on classifying and identifying the I pig genetic origin and supplying molecular makers for conservation activities. Methods: This study sequenced the complete mitochondrial genome and used the sequencing result to analyze the phylogenetic relationship of I pig with Asian and European domestic pigs and wild boars. The full sequence was annotated and predicted the secondary tRNA. Results: The total length of I pig mitochondrial genome (accession number KX094894) was 16,731 base pairs, comprised two rRNA (12S and 16S), 22 tRNA and 13 mRNA genes. The annotation structures were not different from other pig breeds. Some component indexes as AT content, GC, and AT skew were counted, in which AT content (60.09%) was smaller than other pigs. We built the phylogenetic trees from full sequence and D loop sequence using Bayesian method. The result showed that I pig, Banna mini, wild boar (WB) Vietnam and WB Hainan or WB Korea, WB Japan were a cluster. They were a group within the Asian clade distinct from Chinese pigs and other Asian breeds in both phylogenetic trees (0.0004 and 0.0057, respectively). Conclusion: These results were similar to previous phylogenic study in Vietnamese pig and showed the genetic distinctness of I pig with other Asian domestic pigs.

  • 산업발전과 인구증가, 생활수준의 향상으로 하·폐수 발생량 및 하수처리장 연계처리수가 매년증가 하고 있다. 연계처리수는 저유량 고농도의 특징을 가지고 있다. 따라서 하수처리장 운영에 큰 영향을 미치고 연계처리수를 처리하기 위해 많은 비용도 사용되는 것으로 나타났다. 본 연구에서는 연계처리수의 유입 유량을 개별 반응조로 전량 유입시킬 경우 방류수 수질이 적게 상승한 시나리오를 도출했고, 모델링 결과 유입하수, 무산소조에 유입시킬 경우 방류수 수질이 가장 적게 상승하는 것을 확인할 수 있었다. 이와 같은 결과를 바탕으로 연계처리수의 유입 유량을 유입하수와 무산소조로 분배하여 유입시킬 경우에 대하여 분배 비율에 대한 다양한 시나리오를 생성했다. 다양한 시나리오를 통해 모델링을 진행한 결과 유입하수(80%), 무산소조(20%)의 비율로 연계처리수의 유입유량을 분배 유입 시킬 경우 TN, TP의 수질이 가장 적게 상승하는 것으로 나타났다.
