The coast is important area to set up policies in aspects of environmental, international and developing of resources. The researches and surveying have been conducted by many different organizations according to their own purposes. So the fundamental researches and surveying of Korean coastal area haven't been completed. For that reason, we can't use the datum to apply for different cases. In this paper, Ive studied about our current situations and the need of surveying. For a effective research methods, we suggest dividing research areas into zones and dividing them into smaller zones, And we divide priority of research and ranging of surveying classes by grading them depending on the importance.

This study investigates and analyzes the amount and shape of the front waist dart of the bodice and investigates the dart division method by bust size. Measurements at 5 arm positions were taken from 15 subjects. Clothing tests were given to 6 of the subjects. The conclusions were as follows: 1) Front Body surface changes were occurred around armpit and they were caused by the wrinkles of the armpit 2) The curved dart line was more appropriate for use with C cup, the large bust body, than the linear line. The changes of the dart amount at arm movements had different types by bust size. 3) Patterns for A & C cup body were adequate to divide the dart amount by 3 darts such as under the B.P., under the anterior armpit and side line, or to aggregate to 1 dart under the B.P. For the B cup body, however, the suitable pattern to use was the total dart amount divided by 1~2 darts and decreasing the waist line at the side line should be avoided.

This is a study on the Changes of the Apartment House Managerial Problems to grope for the way of more pratical management about increasing the apartment house in Korea. The documentary research method was used for this study and the Han-Kook newspaper(1954-1991) was used as an ananlysis data. On the basis of it, I examined the changes, such as the number of whole articles by time series and the column of head title. I also classified it into several subjects and analyzed it. Finally, I attemped to divide an chronological section on the Changes of the Apartment House Managerial Problems. On the basis of this study, I expect that various documents, related laws and regulations will be analyzed in no distant future. These is going to make the Apartment House Managerial Problems gave more systemic and efficiency.

흔히 전송매체와 연결되는 물리계층에서는 수신된 데이터열에서 동기를 획득하는 과정이 필요하다. 기가비트 이더넷에서는 PMA에서 PCS로 데이터열을 전송할 때 62.5MHz 두 개의 클럭에 맞추어 교대로 보내는 절차를 표준안으로 채택하고 있기 때문에 수신된 데이터열을 처리하기 위한 125MHz 클럭을 생성해내는 PLL이 필요하다. 그러나 PLL은 구현하기가 어렵다. 다른 대안들로는 FIFO를 활용하는 방법과 62.5MHz 클럭을 이용한 이중 데이터열 처리 방법 등이 있다. FIFO를 이용한 방법에서는 오버플로우가 발생할 수 있으며, 이중 데이터열 처리 방법에서는 표준안과 다른 별도의 수신부 설계가 필요하다. 본 논문에서는 언급한 방법들을 사용하지 않으면서도 표준안을 따르며 비용 효과적인 하나의 방안으로 송신부 클럭에 수신된 데이터열을 재정렬 시킬 수 있는 DSM(Divide-Select-Merge) 방법을 제안한다.

Landslide is a natural disaster frequently noticed In korea during monsoon season in flicting nationwise damages on human lives, properties, transportation networks, construction sites, etc. This study is about landslide characteristic in rainfall. This study selects seven sites that occured in 2001 and 2002. So elect areas divide and studied special quality by carcinoma by igneous rock, metamorphic rock, sedimentary rock. According to study finding, because igneous rock area is very thin into 1m interior and exterior soil layer, failures happened much rock and soil interface. There was place that depth of soil layer becomes about 2∼3m being area that receive serious weathering case of metamorphic rock. Therefore, at collapse much debriflow occurrence expect. Case that sedimentary rock area is broken through stratification looked. When see such results, it may become many helps to study characteristics of landslide occurrence area grasping collapse special quality by rock type.

Since the cut slope has been big concern due to frequent failures, the government decided to include cut slopes in the“Act for Safety Control of Public Structures”. Based on the Act, the cut slope whose height is over 50m and length is over 200m should be inspected on the regular basis. According to the Act, KISTEC developed the objective evaluation method for the condition of cut slope. The evaluation method is divided into two categories: evaluation for damaged condition and evaluation for failure affecting factor. Based on the evaluation results, the cut slope is graded from A to E. In this study, the process to evaluate the cut slope condition and the evaluation criteria to divide the grade of cut slope are introduced.

This paper describes basic structural design for the large floating crane barge of fixed undulation type. Structural analysis is performed to divide two parts because crane barge is composed two parts, crane part of jib boom back stay and back tower and barge part to support crane part. The structural strength for jib boom structure members are in compliance with JIS B 8821 and scantling of all barge structural members are in compliance with the requirement of KR (Korean Register of Shipping) Steel Barges and Rules for Classification of Steel Ships. For the structural analysis of large floating crane, MSC/NASTRAN & MSC/PATRAN software is used.

This paper presents a simulation method using the transmission line modeling to reduce simulation runtime of hydraulic control systems. This method is based on separating the system components each other using the transmission line elements prior to simulation, which leads to divide the simulated system into several subsystems suitable for an even more efficient integration. It can also handle nonlinearities and discontinuities without flag signal when restarting integration. By applying variable integration timestep to parallel hydraulic circuits via parallel processing, it is shown that simulation run-time can be reduced significantly compared with that of Runge Kutta method.

Sharing Economy is the modern main item with ICT Development. Of course sharing economic item is the old and long run mainstream, but by the ICT technological development sharing economy is the fostering and affluent factors in the world economic growth. Though, in Korea, till now sharing economy is minimal, that will growth sharply. We can track various business models of sharing economy. Sharing economy is to buy use right not ownership. With the sharing economic business model wee can make also financial sharing model. In finance model we can divide two kind models. First, we can trace small size lending model with p2p type. And second, we can make financial information transaction model. But till now sharing economic system is not activated, because of many reasons. To activate, first we have to set law and various standards, and also government actively support many sharing economy firms and institutions. To catch up developed countries in the field of sharing economy we have to make aggressive and flexible rules and standards.

The typical life cycle of filamentous fungi commonly involves asexual sporulation after vegetative growth in response to environmental factors. The production of asexual spores is critical in the life cycle of most filamentous fungi. Normally, conidia are produced from vegetative hyphae (termed mycelia). However, fungal species subjected to stress conditions exhibit an extremely simplified asexual life cycle, in which the conidia that germinate directly generate further conidia, without forming mycelia. This phenomenon has been termed as microcycle conidiation, and to date has been reported in more than 100 fungal species. In this review, first, we present the morphological properties of fungi during microcycle conidiation, and divide microcycle conidiation into four simple categories, even though fungal species exhibit a wide variety of morphological differences during microcycle conidiogenesis. Second, we describe the factors that influence microcycle conidiation in various fungal species, and present recent genetic studies that have identified the genes responsible for this process. Finally, we discuss the biological meaning and application of microcycle conidiation.
