  • Conventional studies concerning about economic evaluation of fisheries damages caused by public undertakings have focused on showing the causality between marin environmental variation and fisheries production. But almost all of them have ignored the effect of fisheries damages factors on fisheries price. The study tries to suggest a model how to examine the existence and measurement of the effect of fisheries damage factors on fisheries price using statistical approach, in other words, the estimation of the statistical coincidence between two different population means. The paper tries to give a good application of the model using the case of fisheries damages caused by oil leakage pollution which happened three years ago in the coast of Taean province.

  • For the assessment of ultimate longitudinal strengths of damaged hull girders, it is preliminarily necessary to determine the extents and locations of the damages due to severe accidents. This paper deals with the estimation of the damages from collisions and groundings of large-sized vessels where deterministic and probabilistic approaches are investigated. Deterministic damages estimated from MARPOL(or ICLL), ABS and DNV are compared with probabilistic damages from IMO guideline and some references including damage statistic data. Damages from MARPOL show largest one among all the investigated damage estimation, since it was developed not for the residual strength of hull girder but for the damage stability calculation. IMO guideline with high level probability of damage(eg. 95% probability level) also forecasts even severer damage extents than MARPOL. On the other hand, assuming average probability level of damage, the calculated damage sizes are around the one from deterministic approaches.

  • The paper aims to explore existence and degree of remaining fisheries damages after the completion of undertaking the Four Major Rivers Project focusing on the case of Yeongsan river. The paper seeks to show the necessity of consideration of periods of fishery resources recovery in the estimation of ex-post fisheries damages of the project by inferring the analysis of the annual variation of environmental indicators in the river. Therefore, the paper suggests three years of remaining periods of fisheries damages of the project utilizing the variation trend of ex-ante and ex-post annual output data of inland fisheries in Jeonnam province and individual catch of fisheries. In the measurement of the annual degree of fisheries damages during periods of fishery resources recovery, the paper attempts to suggest the method of comparision of day catch data per vessel between ex-ante and ex-post periods of the project, which were investigated by the same institute. Here the paper tries to make correction of ex-post catch data for holding the same catching condition as ex-ante situation by adopting the concept of competitive intensity of catching which was derived from the decreasing rate of number of fishing households in the area of Yeongsan river.

  • This paper tries to apply the standard method for the estimation of range and degree of fisheries damages caused by warm water drained by generating plants to a real situation. The theoretic foundation of the study has been shown in the article published on the journal of fisheries business administration of last year. The paper tries to examine the degree of external appicability of the theoretic model through empirical study. The results of the study are as follows. The model has been found a successful device for the estimation of fisheries damages caused by warm water drained by generating plants. It also shows a possibility to work in any other fisheries damage cases caused by several kinds of public undertaking on coastal areas. The key of the model is the successful derivation of the quantity amount of the critical variation of environmental factors for example, in this case, water thermal variation. Therefore the countinous and appropriate collection of law data on the environmental factors under a viewpoint of statistics is essential to the usefulness of the model.

  • This study attempts to suggest a new approach of the estimation of range and degree of fisheries damages caused by a large scale of reclamation undertaken in coastal area using the central limit theorem(CLT) in statistics. The key result of the study is the introduction of the new concept of critical variation of environmental factor($d_{c}$). The study defines $d_{c}$ as a standard deviation of the sample mean($\bar{X}$) of environmental factor(X), in other words, $\frac{\sigma}{ \sqrt{n}}$. The inner bound of $d_{c}$ could be the area of fisheries damages caused by public coastal undertaking. The study also defines the decreasing rate of fisheries production$\delta_{\varepsilon}$, in other words, degree of fisheries damages, as the rate of change in the distribution of sample mean(($\bar{X}$), caused by the continuous and constant variation of environmental factor. Therefore $\delta_{\varepsilon}$ can be easily calculated by the use of table of the standardized normal distribution.

  • 남북 간의 교류와 협력은 그 과정에서 불가피하게 여러 가지 법적 분쟁을 야기할 수 있는데, 그 중에 하나가 인신사고로 인한 손해배상 문제이다. 이 글의 목적은 인신사고로 인한 손해액 산정에 관한 북한법의 내용을 살펴보고 이를 남한법과 비교함으로써, 남북한 주민 간의 손해배상사건에 있어서 분쟁해결의 기준을 제시하는 데 있다. 향후 남북간의 교류와 협력이 확대될 것으로 예상됨에 따라, 북한의 손해배상법에 대한 이해는 매우 중요하고 시급한 과제이다. 남한 민법에는 인신사고로 인한 손해액 산정과 관련한 구체적인 규정을 두고 있지 않기 때문에, 손해액 산정에 관한 구체적인 기준은 법원의 판례를 통해서 정해지게 된다. 남한의 법원은 인신사고로 인한 손해를 적극적 재산상 손해, 소극적 재산상 손해, 정신적 손해로 나누어서 각각의 손해액을 산정한다. 반면, 북한 손해보상법은 인신사고를 1) 건강을 침해한 경우(제41조), 2) 건강을 침해하여 장애를 남긴 경우(제42조), 3) 인신 침해로 사망에 이르게 한 경우(제44조)로 나누어서 그에 따른 손해의 항목을 구체적으로 규정하고, 손해액 산정에 관한 규정(제43조, 제51조)을 두고 있다. 또한, 남한에서는 신체사고에 대한 정신적 손해배상을 넓게 인정하고 있으나, 북한에서는 정신적 손해배상을 원칙적으로 인정하고 있지 않다.

  • A damage estimation method for support structure of offshore wind turbine using modal parameters is presented for effective structural health monitoring. Natural frequencies and mode shapes for a support structure with monopile of an offshore wind turbine were calculated considering soil condition and added mass. A neural network was learned based on training patterns generated by the changes of natural frequency and mode shape due to various damages. Natural frequencies and mode shapes for 10 prospective damage cases were input to the trained neural network for damage estimation. The identified damage locations and severities agreed reasonably well with the accurate damages. Multi-damage cases could also be successfully estimated. Enhancement of estimation result using another parameters as input to neural network will be carried out by further study. Proposed method could be applied to other type of support structure of offshore wind turbine for structural health monitoring.

  • 최근 급속한 경제발전과 온난화로 인해 이상기후 현상이 빈번하게 발생하고 있다. 자연재난의 유형 중 풍수해에 해당되는 호우, 태풍, 강풍, 풍랑, 대설 등은 대규모 인적·물적 피해를 발생시킨다. 피해를 최소화하기 위해서는 재난발생 전 피해규모를 예측하는 것이 중요하다. 본 연구는 풍수해의 재난유형 중 강풍피해를 중심으로 재난에 대비할 수 있는 강풍피해예측함수를 개발한다. 본 함수는 재해 연보의 강풍피해이력을 기반으로 기상요소와 지역적 특성을 반영하였으며, 기상정보를 실시간으로 수집할 수 있는 시스템에 탑재할 경우 단시간에 피해규모를 예측할 수 있다. 또한, 본 함수는 국가 혹은 지자체에서 수립하는 재난관리정책에 근거자료로 활용하여 강풍발생 시 피해를 최소화할 수 있다.

  • A quantitative method was suggested for estimating damages in fishery production due to the diffusion and deposition of suspended silt and clay by various construction processes in tidal flat fishing grounds. Marine populations are maintained through the process of spawning, growth, recruitment, natural death and death by fishing each year. All of the year classes of the population in a fishery ground could be affected when damages occur by human activities such as land filling or reclamation. The propose of this study is to calculate damages in terms of fishery production using a quantitative population dynamic method. If the maximum age in the population is $X_\lambda,$ the starting year of damage is $t_s,$ and the ending year of damage is $t_e,$ the number of year classes damaged is $t_{s-n\lambda}-t_e,$ Many year classes present in the year $t_s,$ and so if damages occur, they Influence all the year classes which are present in the population. Damaged year classes in year $t_e$ would still be in the population until the year $t_{e+n\lambda}$, where $n_{\lambda}$ is the oldest age class. If the expected yield of a year class is constant, the total yield from year classes in the fishing ground during the construction periods can be calculated as follows: $Y_\Phi=[(t_e-t_s+1)+n_c]{\cdot}Y_E+\sum\limits^{n_\lambda-n_c}_{l=1}\;\sum\limits^{n_\lambda-n_c}_{l=i}\;Y_{n_c+i}$ This method was applied for damage estimation in the production of Ruditapes philippinarum in a tidal flat fishing ground.
