Class area is a portion of memory where the constants, fields, and codes of the classes loaded into the Java virtual machine are kept. Knowing the site of the class area is very important especially for embedded Java system with limited memory resources. This paper induces a formula which makes it possible estimate the size of the area. The formula needs some constant values specific to target JVM implementation. We also show that these values can be found using some simple probe classes. An experimental result is included in this paper to confirm the correctness of our approach.

우리나라는 국토에서 산림이 차지하는 비율이 매우 높기 때문에 산불은 방재에 있어서 중요한 요소로 취급된다. 산불 피해 면적 산정은 향후 복원계획을 수립함에 있어서 예산 수립이나 물량 산출에 기초가 되는 중요한 자료이므로 정확하게 산정되어야 한다. 우리나라에서는 산불이 발생되면 GPS를 이용하여 피해 면적을 조사하고 있다. 그러나 실제 산불 피해 면적을 산정하는 데 있어서는 여러 가지 문제로 인하여 신속하고 정확한 산정이 잘 이루어지지 않고 있다. 우리나라의 산불 담당 기관인 산림청은 전국을 대상으로 하여 충분한 수의 산림 헬리콥터를 운용하고 있다. 따라서 산불 피해가 발생한 후에 산림 헬리콥터를 이용하여 피해지역을 디지털 카메라로 사진 촬영하는 것이 가능할 것이다. 본 연구에서는, 공중에서 디지털 카메라로 스냅 촬영한 산불 피해 지역 사진을 이용하여 그 피해 조사를 수행할 수 있도록, 여러 가지 처리 방법을 비교 고찰함으로써 적합한 방안을 정립하였다. 본 연구의 결과는 향후에 디지털 사진을 이용한 산불 피해 조사 시스템 개발에 유용하게 활용될 수 있을 것이다.

The purpose of the present study was to generate a list of business ethics components according to business area for small and medium-sized fashion companies. Based on the literature review, 21 components of business ethics components were identified within five business areas. Ten CEOs(Chief Executive Officers) each participated in an in-depth interview, sharing ethical and unethical cases from their own businesses. Constant comparative analysis was used to generate important business ethics components from those cases. In results, important business ethics components for each business area are: 1) using human-friendly materials, strengthening sustainable technologies, using vegan materials, concerning safe process, and reducing waste in the material production and sourcing area, 2) enhancing an efficiency in design, developing recycle/reuse designs, avoiding to copy designs, and using messages for public interest in the product design area, 3) concerning fair-trade, reducing harmful substance, saving energy, and using ethical supply channels in the distribution and logistics area, 4) acquiring certifications, promoting consumer protection, avoiding exaggerative/false advertisements, and promoting social contributions in the management and marketing area, and 5) promoting workers' rights, complying with the law, and investing on employee educations in the labor management area. All of the ethical and unethical cases of the ten companies have involved aspects of the 21 components, thereby enhancing understandings on how each issue is being seriously considered and/or handled in the small and medium-sized fashion companies. Study findings may provide a basis for development of a research model for quantitative studies and/or educational programs related to business ethics in the fashion industry.

The purpose of this study is to gather baseline data on perceived housing values and satisfaction rates among consumers with the aim of using this information for future planning. Self-administered questionnaires were provided to 1000 university students from Gwangju and the Chonnam area from 2007 October 8th to 30th. The collected data was used to conduct comparative and descriptive statistical analysis: factor analysis, cluster analysis, t-test, $x^2-test$ and one-way ANOVA. The main findings are as follows: Firstly, in relation to perceived house values, students identified three factors as important: pursuit of convenience, disposition toward individuality-orientation and consciousness of others. The respondents regarded convenience as very important, especially in regard to one's safety, health and location of amenities. Secondly, cluster analysis based on perceived house value revealed passive and energetic types. Students in the energetic type exhibited a tendency to prefer convenience, independence, and consciousness of others. Finally in terms of housing satisfaction, the respondents identified four factors as important: house quality, neighborhood environment, local socio-psychological environment, and location. Housing satisfaction was higher among students who lived in large or new houses, shared the same house with their family, and had a room all to themselves. Accoding to these findings, university students important value safety, health and environmental-friendliness in a house and they find location important. Therefore, future houses should reflect these wants.

Perceived age is defined as age estimated based on physical appearance. Perceived age is an important indicator of the overall health status of the elderly. This is because people who appear older tend to have higher rates of morbidity and mortality than people of the same chronological age. Although perceived age is an important indicator, there is a lack of objective methods to quantify perceived age. In this paper, we construct a quantified perceived age model from face images using a convolutional neural network. The face images are enlarged to super-resolution and the skin, an important feature in perceived age, is made clear. Moreover, through Tanh-polar transformation, the central area of the face occupies a relatively larger area than the boundary area, helping the neural network better recognize facial skin features. The experimental results show mean absolute error (MAE) of 6.59, showing that the proposed model is superior to existing method.

To Determine the major factor which causes the accelerated calcification of the severe flexing area of the artificial heart sac, comparative study under well defined in vitro situation were carried out. The results show that the effect of static mechanical stress is not so important. According to the data, change of surface area caused by the applied mechanical stress is one of the important factors of the heavy calcification of the severe flexing area of the artificial heart sac.

Korea has experienced many changes since modern hospitals started to be built. Among these changes, interest in 'Promotion of Curing environment', which is the most fundamental one of the hospital functions, has increased more and more. The lobby makes the first impression of a medical building and that is an important function. Recently, the lobby became highly valued not only as a waiting area or a pathway only but as a cultural area. The lobby is considered simply as a complex and busy area because it plays an important role in the building' communications and access systems and has various uses and functions. Based on the concept of curing environment, the lobby can be planned as a facility combining culture and medical functions by applying multi therapy.

We display important test information from radar, telemetry in real time for monitoring and control of guided missile flight test. Clearing test area is the most important thing for safety. Thus, we have to constantly monitor and control ships around the test area. Several maritime surveillance radars are deployed around the test area for that purpose. However, multiple points are displayed for the same target when using multiple surveillance radars and this confuses the test personnel during the mission. In this paper, we suggested a method to solve this problem by analyzing error factor of surveillance radar and comparing the correlation of each radar data.

During the traditional periods when there were exchanges among Korea, China and Japan based on ocean currents or seasonal winds, the southwestern coastal areas including Yeosu held an important position since the route would not have been complete without them. Armed with its advantages including the marine environment, the Yeosu area in the southwestern coast on the Korean Peninsula engage in active maritime exchanges and activities as a base along the sea route since the Neolithic or Bronze Age. It was the same later when Baekje and Gaya had exchanges with China and Japan, when Unified Silla had exchanges with China, and when Goryeo had exchanges with China and Japan. In Joseon, the Yeosu area gained fame as a marine defense base. In short, the Yeosu area in the southwestern coast on the Korean Peninsula during the traditional periods not only engage in active maritime exchanges and activities, but also serve as an important base that could not be left out in the maritime history of East Asia.
