The research was carried out to investigate the related phenomena, the latent structures and synfhetical characteristics in various growth factors of Phyllostachys bambusoides Sieb. et Zucc. growing at Damyang gun, Chollanamdo, using multivariate analysis. 1. By synthetical characteristics in canonical correlation between height-growth factor group and diameter-growth factor group, the former was determined by the culm height (x₁), and the latter by the. diameter of the largest internode(x_7). And for those between quantitative growth factor group and qualitative growth factor group, the former was determined by the surface area(x_(10)), and the latter by the diameter of the largest internode (x_7). 2. The ten growth factors of bamboo culm were simplified by two principal components on the basis of accumulated proportion aimed at 90%. The first principal component(Z₁) as a $quot;size factor$quot; showed high correlation with growth factors except eye-height diameter(x_5). The second principal component (Z₂) as a $quot;shape factor$quot; showed high correlation only with x_5. 3. The bamboo culm, and the latent phenomenon between their growth factors could be determined by two common factors showing high communality(94.16%). The ten growth factors can be grouped into two attribute factors: quantity and quality. 4. The bamboo culms can be classified into five types: total, volume, shape-quality, inferior and middle.

소형어선 검사제도 현실과 개선방안

이광남,Lee Kwang-Nam 해양환경안전학회 2005 海洋環境安全學會誌 Vol.11 No.2

소형어선 검사제도와 관련하여 최근에 정부에서는 선박검사대상에 제외되었던 선외기등 총톤수 2톤 미만의 선박(이하 소형어선)에 대하여 선박안전법 적용대상으로 확대하여 어민들의 안정적인 조업활동을 지원하여야 한다는 근거하에 선박안전법 개정(제3조)에 관한 입법이 추진중에 있다. 소형어선의 검사여부 문제에 대해 어선의 안전확보 차원에서 검사를 해야 된다는 측면과 영세민과 노년층으로 현행 검사비 및 검사수수료의 비용 부담 및 어선검사를 받는데 소요되는 많은 시간 등의 문제로 종전과 같이 검사대상에서 제외되어야 한다고 주장하고 있다. 이러한 상반된 의견에 대한 대안으로 영세어민의 생업에 사용하거나 소형어선에 대한 검사는 원칙적으로 선박의 소유 또는 사용자가 자발적으로 수행하여야 하며 행정적인 규제는 이러한 목적 달성을 위한 최소한의 정책수단으로 제한되는 것이 바람직한 것으로 나타났다. 또한, 주요 수산국들 처럼 우리나라도 소형어선 검사를 위한 다양한 프로그램개발이 필요하다. 특히, 소형어선에 대한 검사를 실시하는 경우, 어선검사료 정부 지원, 최소한의 안전확보 검사, 어선건조시 검사, 검사기간을 연장하는 방안을 고려하여 정책을 추진할 필요가 있는 것으로 파악되었다. In relation with inspection systems of small fishing vessels, Government is drawing up revision of the law about ships safety act(Article 3) on the basis of supporting safe fishing activities to expand the application range of ships safety act for vessels under 2 tons(small fishing vessels) that are exempted from inspection systems. There are two opinions about inspection of small fishing vessels. Government's opinion is that inspection of small fishing vessels must be enforced to confirm small fishing vessels' safety but fishermen's opinion is that inspection systems keep on existing law because inspection systems spends a lot of time and money to the poor and the old. The alternatives for countered opinions is that the poor fishermen's vessels' for living or small vessels' inspection must be operated by themselves in principle and minimizing the limitation through policies is recommended. In addition, Government needs to develop various programs for inspection systems of small fishing vessels like the main fisheries countries. Particularly, in case of operating inspection systems of small fishing vessels, Government needs to consider some solutions for example supporting inspection fee, minimum inspection for confirming vessels' safety, inspecting when a vessel is building, expanding an inspection period.

This experiment was carried out to distinguish between picea abies (L.) Karsten and Picea koraiensis Nak by the method of discriminant analysis which is used the metrical continuous characteristic on current inorphological plant taxanomy. The results are summarized as follows 1) The discriminant function and discriminant region from the experiment are Z(x)=Z(x₁,x₂)=0.000379x₁+0.004354x₂-0.311061or Z(x)=Z(x₁,x₂)=0.000379(x₁-60.442800)+0.004354(x₂-66.185100)R₁=(x│0.000379x₁+0.004354x₂-0.311061≥0), R₂=(x│ 0.000379x₂+0.004354x₂-0.311061<0). 2) The probability of misclassification based on the above discriminant region is P(2│1)=(P1│2)=0.444 therefore the probability of simultaneous misclassification of P(2│1) and P(1│2) is about 44.4%. 3) the probability of misclassification by the discriminant function resulted from the experiment if recorded as high but it is thought that there is a considerable meaning to perceive the probability of confidence about the discrimination better than its precision

As of late, people who enjoy fishing as a pastime in Korea has dramatically increased on the back of the increased national income and 5-day working system being in place. In the past, people used to fish in inland waters, but fishing on the sea has also shown a steady increase. The expanded fishing community along with increasing types of fishing, however, led to destruction of ecosystem by littering the waters of both inland and sea with wastes and reckless exploitation of fish resources. Fishing activities are usually taking place in inland waters, or on the sea, which is, by definition, a common property, and side effects such as free riding and diseconomy are frequently observed occurring. In other words, everyone can use the property free of charge(except paying fishing lot), and littering the waters with pollutants and wastes stemming from fishing activities is currently rampant. In this context, this paper studies the necessity of introducing fishing license system and its feasibility in Korea from a perspective to improve the national welfare through policy measures based on `polluter pays principle` to prevent further environmental pollution in the fishing lot and preserve fishery resources. Study shows that introduction of Recreational fishing license system is urgently needed, but it is concluded that it should take more time to implement the system so as to accomodate the differing interests of all parties involved including recreational fishing industry, while strengthening public relation activities to solicit for the people`s understanding of the system to be introduced.

This paper analyzed economic feasibility of aquacultural construction which of large-scale. The results of the economic analysis, cage cultural and water recycling cultural by post-water treatment were analyzed that NPV is 2,083,685 thousand won and -14,105,896 thousand won and B/C ratio is 0.590 and 0.855, respectively. These were shown economic infeasibility. But, running water culture by pre-water treatment(small scale) and running water culture by pre-water treatment(large scale) were analyzed that the one is 5,555,747 thousand won and 15,048,589 thousand won and the other is 1,154 and 1,1221, respectively. these were shown economic feasibility. In addition, measurement of B/C ratio through a sensitivity analysis on running water cultural by prewater treatment(small scale) and running water cultural by pre-water treatment(large scale) is economic feasibility in all cases. However, these were analyzed when the selling price was falling to 20 percent, it has shown economic infeasibility and when the selling price rises to 20 percent, water recycling culture by post-water treatment has economic feasibility. The significance of the study analyzed a sensibility as well as economic feasibility by methods and scales. It is expected that used as basic materials when constructing and operating of land aquaculture in order to minimize the damage from natural disasters.

Due to red tide and abnormal currents that take place every year, the damage of inland fish farms that takes sea water is increasing frequently. Also, the households of inland fish farm due to the increase in the cost of fuel and electricity are struggling many hardships economically. In relation to underground seawater for it’s farm analyzed economic effect based on the actual conditions for 1,700 inland fish farms, from this I have deduced policy implications for direction this project to be pursued from now on. The saving rate of costs of the fuel and electricity through the development of an underground seawater were approximately analyzed to decline about 3.4~9.7%, if utilizing only about 5% of the undeveloped farms, it was estimated effect of about 61 billion won, if 10%, it was estimated effect of about 122 billion won. Consideration in selecting the developer of underground seawater will be selected an character of farm method. It is expected this study will be helpful for business analysis related government in the fisheries.

It is necessary to come up with fundamental countermeasures about various enforced business in the fisheries suffered as a result of the oil spill by Hebei Sprit Oil Spill in Dec. 2007. Many fishermen lost their properties by this oil spill accident. Not to be solving a disater compensation, fishermen are suffering to keep their living. The existing issues in the marine oil spill accident are to reduce to the minimum their damages from oil spill. pollution(PAHs, benzo(a)pyrene) of fishing ground, which was caused by oil spill, should be decreasing fishery industry in the future. Fishery industry need improvement measures for oil spill. Because it will be happen frequently oil spill accidents due to be surrounded by water on the three sides.. In order to make progress of the fisheries, we have to seek for solution to over come problems of marine accidents.. The government has come up with the solution to the compensation mony from IOPC funds for fisheries.. Therefore we try to draw up guidelines on the preventive measures against oil spill.

The importance of bamboo as raw material for bamboo wares and several kinds of industrial products is highly appreciated at home and abroad. But different kinds of bamboo-bundle systems have been traditionally used in the local areas. There being no reasonable bamboo-bundle system, we have a lot of difficulty in trading bamboo products and executing adrinistmative works. Therefore, a reasonable bamboo-bundle system based on scientitic proofs needs to be tested and established for fair trade and administration. This study is carried out to solve the above difficulty with statistical investigation and analysis. The results obtained are as follows. 1. The larger the circles at eye-height become, the more the possibility of the largest internode covering the span between eye-height and 1/4 height increases. 2. The longest internodes are distributed according to a rule without relation to circles at eyeheight. 3. The tapering grade of bamboo culms is very high and its form is almost the same without relation to its size. (Form exponent; 0.71-1.05, eye-height form factor; 0.60-0.66, 1/4 becomes, seeing that the circle grade and the percentage of actual volume height form factor; 0.61-0.69). 4. The larger the circles at eye-height are, the lower the percentage of actual volume have negative curve relation to each other. 5. It is considered that the numbers of bamboos bundled in a $quot;Sok$quot; is not decided according to the usefulness of bamboos, judging from the fact that the outputs of bamboo wares per $quot;Sok$quot; in every circle grade are not the same. 6. As the results of the regression analysis, the empirical formulae of several amounts to circles at eye-height and culm length are as follows; Vonume, y_i=3.821874+2.013181 log Ci+0.839128 log Hi V=0.0066355 C^(2+013181) H^(0.839128) Actual volume, y_(ai)=3.915338÷0.776549 log Ci÷1.857000 log Hi Va=0.0082288 C^(0.776549) H^(0.857000) Weight, wi=3.869148+1.936410 log Ci÷0.566904 log Hi W=0.0073986 G^(1.836410) H^(0.565904) 7. Korean Phyllostachys bambusoides Sieb. et Zucc. is almost the same as that of Japan in several amounts, just the same especially in the weight. 8. It is found that the bamboo-bundle systems of Korea and Japan have much closer relation to the weight than other amounts. So It is, therefore, considered that the weight is important factor in deciding bamboo-bundle system. 9. According to the item 8, I should like to propose the appropriate numbers per $quot;Sok$quot; adjusted on the basis of the weight in the Table 18.
