  • It is very important to collect all production-related status values during the manufacturing process of semiconductor. The analysis results of the collected data can be used for the operation rate, fault diagnosis, process control and removal of predicted obstacles of equipments, eventually contributing to the improvement of production efficiency. For this propose. many IC makers have adopted EES(Equipment Engineering System). As the use of web has become a daily lift activity lately, it has been suggested to expand the scope of monitoring equipments using HTTP or SOAP protocols. To fulfill the web-based EES, EDA(Equipment Data Aquisition) should be facilitated first by integrating and standardizing various forms of messages generated from many different semiconductor equipments. In this paper, a method for integration between different types of information is suggested based on the analysis of various protocols used for the communication between semiconductor equipments. In addition, a software architecture to support the method is desisted.

  • Korea is presently the leading country in global desalination industry and has been investing a large amount of money and human resources in development of new core technologies to increase its' share of global market. In this paper, we reviewed world-wide trends of the advanced water industry and outlined various seawater desalination technologies developed so far. We also made some analysis on the directions and results of the government-lead R&D sponsorship in the field of seawater-freshening technology. Present studies showed that we need an institutional strategy to help domestic companies guarantee the credibility of the technologies developed by themselves based upon their experience of plant operation. Futhermore, strategic R&D programs to develope original technologies and localization of key components for desalination plants should be preceded in the near future.

  • Remote sensing sensors used in satellites or aircrafts measure electromagnetic waves passing through the earth's atmosphere, and thus the information on the surface of the earth is affected as it is absorbed or scattered by the earth's atmosphere. Although satellites have different wavelength ranges and resolutions depending on the purpose of onboard sensors, in general, atmospheric correction must be made to remove the influence of the atmosphere in order to accurately measure the spectral signal of an object on the earth's surface. The purpose of atmospheric correction is to remove the atmospheric effect from remote sensing images to determine surface reflectivity values and to derive physical parameters of the surface. Until recently, atmospheric correction algorithms have evolved from image-based empirical methods or indirect methods using in-situ observation data to direct methods that numerically interpret more complex radiative transfer processes. This study analyzes the research records of atmospheric correction algorithms developed over the past 40 years, systematically establishes the current state of atmospheric correction technology and the results of major atmospheric correction algorithms and presents the current status and research trends of related technologies.

  • Because the treatment of a physician generally pertains to the intrusion into body of a patient, his/her consent is a must in order for such conduct to be justifiable. To ensure effective consent of a patient, the physician should fully inform him/her of kind and details of the disease and way of treatment and risks associated with it. The patient can, then, make a decision whether he/she should accept any treatment or operation, if necessary, on the basis of such information. The obligation of physicians to explain has since long been recognized as important in view of guaranteeing the rights of patients for self-decision and protecting them from arbitrary assessment of physicians for treatment. Progress has been made in this respect even to the extent that physicians treat patients on equal terms and think first of all much of establishing trustworthy relationships with patients. Lots of studies in Korea and foreign countries have tried to explore the issues concerning the obligation of physicians to explain in the meantime but seem to have failed to make concrete and versatile approaches from the standpoint of protecting the rights of patients. Wouldn't it be really possible for patients to perceive their own rights and cope actively with the medical treatments? If physicians have full understanding to the rights of patients, they will be put in a better situation to protect themselves and patients, in turn, can identify their own responsibility correctly, which will eventually contribute to fulfilling the goal of treatment. With this background, the present paper examines briefly the obligations of physicians for explanation based mainly on the preceding theories and judicial precedents in the first place and then deals with the status quo and contents of the German medical laws, with a focus on the treaty of European Law 1997 and its working document on the applications of genetics for health purposes that stipulate the detailed criteria on the medical treatment and rights of patients and Germany's $\ulcorner$Charter of Rights for Patients$\lrcorner$ promulgated in 2003.

  • Metal fatigue is an important aging mechanism that material characteristics can be deteriorated when even a small load is applied repeatedly. An accurate fatigue evaluation is very important for component structural integrity and reliability. In the design stage of a nuclear power plant, the fatigue evaluations of the Class 1 components have to be performed. However, operating experience shows that the design evaluation can be very conservative due to conservatism in the transient severity and number of occurrence. Therefore, the fatigue monitoring system has been considered as a practical mean to ensure safe operation of the nuclear power plants. The fatigue monitoring system can quantify accumulated fatigue damage up to date for various plant conditions. The purpose of this paper is to describe the fatigue monitoring procedure and to introduce the fatigue monitoring program developed by the authors. The feasibility of the fatigue monitoring program is demonstrated by comparing with the actual operating data and finite element analysis results.

  • The prime objective of this study is to analyze tourist's behaviors and satisfaction of the Gwangneung area and get a reading on the tourist's socio-economic traits and the propensity of activities. In addition, it highlights surveys of the tourist's consciousness of cultural, ecological and environmental tourism resources available in the Gwangneung area and the possibility for sustainable development and ways to make the most of these resources. This study found that even though Gwangneung is mostly a place for one day family outings. the tourist's demand for actually unreachable ecological resources is high while existing cultural tourism resources have less than the expected drawing power. It was also found that tourists recognize the need for preservation of the tourism resources of Gwangneung and its potential for further sustainable development. In particular, most tourists to Gwangneung are relatively satisfied with the status of preservation of its cultural and ecological resources and environment On the other hand, accessibility, tourism facilities, and management are estimated at less than desired. Gwangneung would benefit by making efforts for the positive use of its tourism resources and improvement of convenience facilities, management and operation.

  • This study describes how the illustration book of Korean coastal and offshore fishing boats was published. The illustration book provides information on fisheries which need boats for their fishing operation. The book contains 25 fishing boats belonging to 15 offshore fisheries and six boats belonging to five coastal fisheries totalling 31 boats belonging to 20 kinds of fisheries. Until now, no books were available in Korea on fishing boats which provided illustrated descriptions of their use in fishing. We carried out field and literature surveys of fishing boats for three years (2016-2018) and the results were compiled into three-dimensional modeling images with schematic drawings of fishing boats, along with text explanations. The particulars and technical drawings of lines, general arrangement (GA), fishing gears and methods are collected and summarized. All fishing boats are modeled with 3D color graphics. The particulars and names of the main items of the fishing equipment are presented besides structural parts. In addition the fishing gear, fishing season and grounds, number of crews and target species for each boat are correctly described. The illustration book of Korean coastal and offshore fishing boats will contribute to understanding the current status of fishing techniques in Korea and will assist in developing new types of fishing boats.
