Through the harmony of natural and artificial systems a city is composed of, the ecology-oriented urban planning seeks for qualitative improvements of a city on which our life is based. To enhance the ecology-oriented urban planning, the followings are suggested by a comparative analysis of Korea with Germany regarding the development process, the instruments, and the establishment of indicators for the planning. Firstly, though our national land development plan is closely connected with B-plan, it has little to do with the natural environment. Moreover, the natural environment plan of the Ministry of Environment is almost impossible to carry out in terms of urban construction work. For this reason, the instrument for dealing with the development and environment plan systems together as well as the completion of the current plan system is needed for the ecologically acceptable urban development in the long term. Secondly, in order to realize what is mentioned above in the concrete it seems to be desirable for the system and the instrument to be devised at the extent of B-plan. The regulations of the plan should have strong legal binding force and practicality as well. The element of ecology-oriented urban planning are (1) degree of independence and appropriate density, (2) conservation of natural elements such as soil, water, animals and plants etc., (3) energy saving in land use, (4) activation of B-plan and inducement of active participation of residents. Thirdly, it will be useful to develop various kinds of indicators for the environment plan provided in advance so that the ecology-oriented urban developments may be under control. It also should be taken into consideration that the indicators are supposed to be comprehensive, representative, and practical enough to make the most of at the early stage of drawing up a plan. The kinds of indicators which can be used in the ecology-oriented urban development include (1) soil, (2) water, (3) vegetation and plants, (4) animals, (5) climate, and (6) transportation.

Objectives : This study is aimed at developing and discussing the prediction model of blood stasis pattern of traditional Korean medicine(TKM) using machine learning algorithms: multiple logistic regression and decision tree model. Methods : First, we reviewed the blood stasis(BS) questionnaires of Korean, Chinese, and Japanese version to make a integrated BS questionnaire of patient-reported outcomes. Through a human subject research, patients-reported BS symptoms data were acquired. Next, experts decisions of 5 Korean medicine doctor were also acquired, and supervised learning models were developed using multiple logistic regression and decision tree. Results : Integrated BS questionnaire with 24 items was developed. Multiple logistic regression models with accuracy of 0.92(male) and 0.95(female) validated by 10-folds cross-validation were constructed. By decision tree modeling methods, male model with 8 decision node and female model with 6 decision node were made. In the both models, symptoms of 'recent physical trauma', 'chest pain', 'numbness', and 'menstrual disorder(female only)' were considered as important factors. Conclusions : Because machine learning, especially supervised learning, can reveal and suggest important or essential factors among the very various symptoms making up a pattern identification, it can be a very useful tool in researching diagnostics of TKM. With a proper patient-reported outcomes or well-structured database, it can also be applied to a pre-screening solutions of healthcare system in Mibyoung stage.

The efficiency of wind turbines (WT) is primarily reflected in their ability to generate electricity at any time. Downtimes of WTs due to "conventional" inspections are cost-intensive and undesirable for investors. For this reason, there is a need for structural health monitoring (SHM) systems, to enable service and maintenance on demand and to increase the inspection intervals. In general, monitoring increases the cost effectiveness of WTs. This publication concentrates on the application of two vibration-based SHM algorithms for stability and structural change monitoring of offshore WTs. Only data driven, output-only algorithms based on stochastic subspace identification (SSI) in time domain are considered. The centerpiece of this paper deals with the rough mathematical description of the dynamic behavior of offshore WTs and with the basic presentation of stochastic subspace-based algorithms and their application to these structures. Due to the early stage of the industrial application of SHM on offshore WT on the one side and the required confidentiality to the plant manufacturer and operator on the other side, up to now it is not possible to analyze different isolated structural damages resp. changes in a systematic manner, directly by means of in-situ measurement and to make these "acknowledgements" publicly available. For this reason, the sensitivity of the methods for monitoring purposes are demonstrated through their application on long time measurements from a 1:10 large scale test rig of an offshore WT under different conditions: undamaged, different levels of loosened bolt connections between tower parts, different levels of fouling, scouring and structure inclination. The limitation and further requirements for the approaches and their applicability on real foundations are discussed along the paper.

The adaptive accounting control system can be regarded as an realistic control system which can adapt itself to uncertain enviromental changes. It has characters that can measure the extend to which we attain our goals and give intelligence, which is essential to planning for the future and for decision making. The budget should present the aim of the compilation of the budget and synthesize the limit through the systematic plan about the utilization of resources, because is a financial plan that is used as estimate of future management operations and as a control of it. If we would like to make good use of this business budget as a tool for planning, we should try to opimize all over the business by relating business operation as far as the effective use of the economic resources in business and the supplying of it are concerned and financial budgets to the responsibility unit center. As this paper is about the budgetary management pattern of marketing based on the adaptive accounting control system, I shall begin with a description of the feature and role of responsible accounting system in management accounting. I shall also deal with the Ex ante accounting system and the Ex post optimum accounting system which are essential to the control stage of business budgeting. And finally, accounting to the control process of adaptive accounting system that fit in with the reality, I shall design a budgetary management pattern of marking section. I wish this paper would be helpful to the activity of budgetary management. A budget is an important step of diverging point. Consequently, when we set up a budgetary pattern based on the adaptive accounting system as far as the control accounting is concerned. I believe that the step of responsible accounting will be a more elaborate and scientific step of management.

지금까지 조직의 정렬에 관한 대다수 연구는 비즈니스 전략과 정보기술 간의 정렬에 집중되어 왔다. 더구나 이러한 정렬은 조직의 관점, 시각, 범위 요소를 포함한 전사적이고 통합적인 정렬이기 보다는 관점 등 일부분의 요소를 중심으로 이루어져 왔다. 한편, 전사적 아키텍처는 조직의 구성요소와 이들 간의 상호관계를 전사적이고 통합적으로 제시한 청사진이다. 요즈음 많은 조직들은 이러한 전사적 아키텍처 개념을 기반으로 비즈니스 전략과 정보기술 간의 정렬을 시도하고 있다. 그러나 이러한 전사적 정렬 방법은 아직 개념적이고 추상적인 수준에 머무르고 있는 실정이다. 따라서, 본 논문은 기존의 부분적인 정렬보다 구조화된 전사적 정렬 방법을 제시하고자 한다. 이를 위하여 기존의 연구 결과를 분석하고, 전사적 아키텍처 개념을 기반으로 관점, 범위 및 시각 등 3차원 요소를 포함한 전사적 정렬을 위한 개념적 모델, 논리적 모델 및 물리적 모델들을 제안한다. 마지막으로 제안된 모델이 기존의 모델들 보다 조직의 구성요소를 전사적으로 정렬하는데 적합함을 비교 및 평가를 통하여 보여주고 있다.

This study goes into the field of CosPlay that takes place in Korea, and directly observes the people who engage in CosPlays. Based on in-depth interviews, this research identified the reasons why the CosPlay aficionados participate in this practice and their cultural preferences. Ethnography methodology was used to understand the behavior of the cultural entities of CosPlays. Moreover, this research attempted to understand their daily formalities through their own perspective and language instead of superficial language. In general, CosPlay form that they manifest is classified into two main categories: those who enjoy posing by becoming their favorite characters and those like to wear the clothes of their favorite characters and go up on the stage to perform an act of animation or game where the applicable character appears. Some of these groups are: 1) 'Bishojo CosPlay' that CosPlays mostly Bishojo cartoon characters and wants to just stand out, 2) 'Aekyo' group that CosPlays merely for the sake of the enjoyment of wearing costumes instead of having the mania-like characteristics, 3) 'CosPlayer Group' who enjoy doing organized team CosPlay in order to present a performance, 4) 'J-Rock CosPlay' group that CosPlay Japanese visual rock groups and prepare to be among a professional CosPlay team, and 5) 'People related to Cospre.com' who try to make CosPlay rooted in as one of new cultures.

It is well known that vital statistics is of great importance as basic data for establishing various range of national policies. Especially, vital statistics is important among demographic information for monitoring and evaluating the population policy, for constructing life table, for making population projection, and for studying various aspects of the society. In principle, the production of vital statistics is based on the registration system. It is, however, still observed that there are some limitations in utilizing fully the registration system due to the inherent problems such as problems in its coverage, accuracies and timeliness. Thus, as an alternative, many countries conduct survey on vital statistics in order to supplement the registration system and obtain in-depth data. Korea is no exception in this aspect. The National Bureau of Statistics carries out the so-called Continuous Demographic Survey. This is a kind of multi-round retrospective survey, covering 32, 000 households and having reference period of one month. The survey has also characteristics of multi-subject sample. Thus, surveys on economic activity status of population, house-hold income & expenditure, and social indicators are together conducted with the same sample. It is, however, found that the survey itself tends to have some quality problems. Especially, the quality problems connected with field data collection are summarized as coverage error, non-response error and response error. Although it is inevitable not to be free from these errors, we should make all our efforts to reduce the errors. The probable schemes pointed out in this paper are as follows : 1) the strengthening formal quality control activities, 2) the review of the survey method, i. e., the combining interview method with mail-sending and mail-back method or pick-up method, 3) well documentation for various cases found in every stage of data collection, and 4) the strengthening the analytical activities. It is, also, emphasized that sincerity of planners and interviewers is the most important factor among other things.

The objective of this study was to know prospect and present state of new variety breeding of Forage and Grassland in South Korea. The industry of forage in Korea is going up to expend through utilization of good quality forage, Italian ryegrass, forage corn and oat rather than rice straw. Especially, since 2007, Italian ryegrass(IRG) had been very important major winter forage crop in South Korea and developed 13 varieties including very early maturity variety (three varieties), early maturity variety (three varieties), medium maturity variety (one variety) and late maturity variety (six varieties). But the disadvantage of Italian ryegrass was weak winter hardness and drought but has good advantage of forage nutritive value, high-yielding and high sugar content, and like livestock as like hanwoo, dairy cattle, goat so on. The Ko-variety (Korea developed variety) of Italian ryegrass has high cold-tolerant and adaptability more than any other country developed variety, and expend to cultivation area from southern area (below Daejeon) to middle-northern area (upper Han river). Although the cultivation area of Italian ryegrass of South Korea was 21,700 ha in 2007, right now, that of Italian ryegrass is about 123,600ha due to expend cultivation area and know famer to good forage crop and have a various maturity varieties (very early, early, medium, late) according to local situation (before-crop harvesting stage or double cropping system). The seed market of Italian ryegrass in South Korea becoming extended to around 100 million Korean won and seed export get nearer to foreign country. We are going to develop of new variety for stress tolerant and high yield and quality forage variety, good adaptability to the Korean environmental conditions including reclaimed area, make self-sufficiency system for forage seed (Italian ryegrass), export our seed to foreign countries.
