For accurate wind resource assessment and wind turbine performance test, it is essential to secure wind data covering a rotor plane of wind turbine including a hub height. In general, we can depict wind speed profile by extrapolating or interpolating the wind speed data measured from a meteorological tower where multiple anemometers are mounted at different heights using a power-law of wind speed profile. The most important parameter of a power-law equation is a vertical wind profile exponent which represents local characteristics of terrain and land cover. In this study, we calculated diurnal vertical wind profile exponents of 8 locations in Jeju Island who possesses excellent wind resource according to the GUM (Guide to the Expression of Uncertainty in Measurement) to evaluate its uncertainty. Expanded uncertainty is calculated by combined standard uncertainty, which is the result of composing type A standard uncertainty with type B standard uncertainty. Although pooled standard deviation should be considered to derive type A uncertainty, we used the standard deviation of vertical wind profile exponent of each day avoiding the difficult of uncertainty evaluation of diurnal wind profile variation. It is anticipated that the evaluated uncertainties of diurnal vertical wind profile exponents at 8 locations in Jeju Island are to be registered as a national standard reference data and widely used in the relevant areas.

클라우드 컴퓨팅은 분산 병렬 컴퓨팅의 일종으로 IT 자원을 가상화 하고 이를 사용자에게 제공한다. 그러나 사용자의 서비스 요청은 시간적 규칙성이 없으며, 이런 이유로 각 자원들은 가용성의 차이를 갖는다. 가용성의 차이는 클라우드 서비스 이용자의 QoS만족도 및 서비스 제공자 선택에 영향을 주게 된다. 본 논문에서는 클라우드 환경에서의 서비스 이용자의 요구에 따라 가상화된 IT자원 제공자의 효율적 선정을 위한 자원 가용성 기반 다중 경매 모델을 이용한 서비스 예약형 클라우드 자원거래 시스템을 제안한다. 제안한 시스템에서는 서비스 이용자의 서비스 요청 발생 시 두 번의 경매 모델을 사용하는 다중경매모델이며, 다중 경매 과정 중 단일 경매 단계에서 자원 가용성 평가 알고리즘 및 가변 큐를 이용한 서비스 예약방식을 적용하여 서비스 제공자의 자원 가용성을 평가하여 최적의 서비스 제공 자원을 찾는다. 제안모델은 QoS만족도 부분에서 앞서 작용한 자원 가용성 평가 알고리즘으로 인해 높은 성능을 보여주며, 작업 처리 시간활용도 면에서 QoS를 모두 고려한 상태로 안정적으로 더 많은 작업을 처리 할 수 있음을 입증하였다.

The purpose of this study is to evaluate on the fitting with human resource practice and strategic on 6 public hospital in the point of resource based view. At the result of this study, public strategy is not much fitted into HRM(human resource management) system, but it shows positive result of the fitting with efficiency strategy and HRM system. These results were associated with the integration of G Medical Center. Generally 6 public hospitals of the HRM system and the strategy had not been linked. They also did not achieve a great outcome. We suggest that the manager in charge of each hospital make strategies of the hospital, and then evaluates about fitting with HRM system. We hope, hereafter, it applied the analysis methods that evaluates it with financing result and individual non-financial result all together.

This study intends to closely examine an evaluation of effectiveness of the HRM associated with interactions among employees(I), purpose recognition(P), role feedbacks(R), and motivative compensation(M). The following is a summary of the results of this research: From the study of the actual situation of the human resource management by the Korean firms, it appeared that the form of existence of vision systems possessed the form of having been written as documents and co-shared. And, although, in the area of motivation endowment and feedbacks, the level of motivation endowment regarding the comprising member by those in charge of departments and the level of reflection of the company's personnel policies in the execution of work by the departments were ordinary, the level of presenting the opinion of the departments regarding the company's personnel policies was shown to be low. And, the decisive elements of wages and the compensation standard were in the order of performance basis and long service. Also, it was analyzed that the leadership style of the CEO is the most important element that influences human resource management policies. And, it was analyzed that in the evaluation of the human resource management area the roles regarding evaluation and compensation, especially, the mutual interactions of the comprising members, feedbacks, and improvement activities are inadequate. And the managerial implications are discussed.

In this study, the development and production of electric vehicles and hydrogen vehicles are presented as a method for realizing carbon-neutral. Accordingly, the demand and need for development of underground metal mineral resources such as copper and nickel has increased. The research was carried out using MT survey, which is very useful for deep exploration such as mineral resources and oil exploration because of it's low cost and explorable depth. In Korea, there are very few cases of MT exploration in terms of mineral development, so the study was conducted based on the MT exploration conducted previously in AusLAMP, Australia. Through comparative analysis of the MT exploration data conducted to identify the ore body in the deep area of the Olympic Dam in Australia, with the data directly calculated in 2D inversion, it was confirmed that it can have a positive effect on the possibility of resource development and carbon neutrality using MT exploration in Korea.

This paper deals with pre-erection scheduling and erection scheduling in shipbuilding. Among shipbuilding scheduling, the ship erection scheduling in a dock is one of the most important since the dock is the most critical resource in a shipyard. However, it is more reasonable to consider pre-erection scheduling and erection scheduling as unified because they compete with the common constrained resources such as labor, crane, space, and so on. It is very hard to consider two scheduling problems simultaneously, and hence, we approach them sequentially. At first, we propose space resource leveling heuristics in pre-erection scheduling given erection date. And then, considering the manpower resource determined by pre-erection scheduling, we also propose manpower resource leveling heuristics in erection scheduling. Various experimental results with real world data show that the proposed heuristics have good performance in terms of scheduling quality and time.

The cloud environment makes it possible to analyze large data sets in a scalable computing infrastructure. In the bioinformatics field, the applications are composed of the complex workflow tasks, which require huge data storage as well as a computing-intensive parallel workload. Many approaches have been introduced in distributed solutions. However, they focus on static resource provisioning with a batch-processing scheme in a local computing farm and data storage. In the case of a large-scale workflow system, it is inevitable and valuable to outsource the entire or a part of their tasks to public clouds for reducing resource costs. The problems, however, occurred at the transfer time for huge dataset as well as there being an unbalanced completion time of different problem sizes. In this paper, we propose an adaptive resource-provisioning scheme that includes run-time data distribution and collection services for hiding the data transfer time. The proposed adaptive resource-provisioning scheme optimizes the allocation ratio of computing elements to the different datasets in order to minimize the total makespan under resource constraints. We conducted the experiments with a well-known sequence alignment algorithm and the results showed that the proposed scheme is efficient for the cloud environment.
