Japanese Ocean Flux Data Sets with Use of Remote Sensing Observations (J-OFURO) includes global ocean surface heat flux data derived from satellite data and are used in many studies related to air-sea interaction. Recently latent heat flux data version 2 was constructed in J-OFURO. In version 2 many points are improved compared with version 1. A bulk algorithm used for estimation of latent heat flux is changed from Kondo (1975) to COASRE 3.0(Fairall et al., 2005). In version 1 we used NCEP reanalysis data (Reynolds and Smith, 1994) as SST data. However, the temporal resolution of the data is weekly and considerably low. Recently there are many kinds of global SST data because we can obtain SST data using a microwave radiometer sensor such as TRMM/MI and Aqua/AMSR-E. Therefore, we compared many SST products and determined to use Merged satellite and in situ data Global Daily (MGD) SST provided by Japan Meteorological Agency. Since we use wind speed and specific humidity data derived from one DMSP/SSMI sensor in J-OFURO, we obtain two data at most one day. Therefore, there may be large sampling errors for the daily-mean value. In order to escape this problem, multi-satellite data are used in version 2. As a result we could improve temporal resolution from 3-days mean value in version 1 to daily-mean value in version 2. Also we used an Optimum Interpolation method to estimate wind speed and specific humidity data instead of a simple mean method. Finally the data period is extended to 1989-2004. In this presentation we will introduce latent heat flux data version 2 in J-OFURO and comparison results with other surface latent heat flux data such as GSSTF2 and HOAPS etc. Moreover, we will present validation results by using buoy data.

It is expected that Korean restaurant business will become one of the most important contributors to the notion's economy by the year 2000. As the many visible and invisible trade barriers are tumbled down and market opening to foreign competition expedites, a strategy to solidify the competitiveness of the restaurant industry is urgently needed. Some of the strateges that need to sharpen the competity edge are as follows: 1. Development of restaurant business management knowhow and enhancement of information gathering capability. 2. Development of its own unique brand of food and service tailored to many different tastes of clientele. 3. Promotion of the industry's globalization efforts with the development of local restaurant brand & Korean traditional foods and with the expansion of foreign investment. 4. Reinforcement of staff training and provision of a compensation package to attract qualified personnel. 5. deregulation of many anachronistic laws and restrictions with government's full support for the industry to realize what it's supposed to be in the 21st century.

Objective : It is recently reported that enema therapy can be effective to enteric disease as well as painful disease, skin disease, immune disease. We look around many reports, books and make a comparative study of colon irrigation, coffee enema, retention enema. Method : I referred to many papers and books about three kinds of enema therapy. Results and Conclusions : 1. Colon irrigation remove fecal inpaction from colon and stimulate perisitalsis by injecting clean water to colon and also increase absorption ability. 2. Coffee enema inject coffee directly to colon, it is effective to detoxification, reducing pain by discharge of bile juice and toxic matters. 3. Retention enema use many kinds of suitable herb medicine to cure different disease by absorption to rectal mucous membrane. It is effective to acute, chronic disease, inflammatory disease.

There are many under grounds facilities like oil pipes, gas pipes, water pipes, oil tanks, etc. and severe corrosion of these facilities made big problems. Fire, wide area water and soil pollution, massive and hazardous explosion, etc. can make big problems and cause big economical loss. So, various technologies were developed to keep these undergrouns facilities safely, and cathodic protection is one of it. For cathodic protection, one must detect potential of pipes, and there are so many test box to check pipes potentials. In this thesis, we describe on the development of small size corrosion monitoring system that measure pipes potentials easily and economically.

There have been vigorous studies on smart home appliances with ubiquitous technologies overseas as well as in Korea. Kookmin university has provided a one-room type test bed as one of many experienced-type test beds and has applied many smart home appliances with ubiquitous technologies to the test bed to examine their interrelations and usability over a year. This article scrutinize applied situations and their problems of the appliances and based on the findings we suggest smart home appliances with ubiquitous technologies in various housing types.

Reliability evaluation of One-Shot system which flies at speed of Mach must be evaluated as the result of many firing tests. But many firing tests are impossible because of budget deficit. Consequently the reliability prediction which substitutes firing tests is used. The accuracy of reliability prediction is decided according to a quantity of accumulated test data. If the test data is insufficient, the direction of prediction can not be set. So we propose the reliability prediction method which applies MIL-HDBK-217 Plus. MIL-HDBK-217 Plus is described about reliability prediction method without sufficient test data. So we apply MIL-HDBK-217 Plus to the rocket motor system, and we accomplish a modeling and a reliability prediction about the system.

Generally SW industry is considered as a high value-added business area. However, many SI companies in Korea have been loosing profits in public business sector. One of the reasons of this problem is because the compensation for the change of work which occurs frequently during a project has been rarely happened. This might be because many contracts have been made as more officer-oriented one. So far, there has not been much study on this topic. So in this paper, we are going to define the change of works in SI projects, analyze the characteristics, and classify them into some categories. After analyzing the current status and related laws concerning this problem, we will suggest a way to solve this problem and show the future research topics.

이동 에이전트의 응용 분야가 다양해짐에 따라 그룹에이전트를 이용한 에이전트 협력 작업이 요구되고 있다. 이런 협력 작업은 에이전트간의 정보 공유 및 작업 제어를 위해 빈번한 통신을 필요로 한다. 본 논문은 그룹에이전트(group agent)들의 효율적인 협력 작업을 위한 CMP를 제안한다. CMP는 동기적/비동기적으로 에이전트 상호간에 보다 융통성있는 정보 전달을 수행한다. 또한, 제안된 CMP 접근 메소드는 1 : 1 통신뿐만 아니라 다 : 다 통신을 지원하기 때문에 그룹에이전트 모델에서도 효율적인 수행이 가능하다.

A new control technique is proposed to reduce the distortion of UPS output voltage. The Load of UPS is rectifier which has many harmonics on its output current in many cases. The distortion of output voltage by the harmonics is repeated at the same position in one cycle. Therefore we can assume that the next cycle wave form would be similar to the previous one. The repeated error can be estimated and be compensated by the Multi controller at every sampling times.

This paper proposes a new detection method of human faces in grey scale images with cluttered background using a facial template and elliptical structure of the human head. Face detection technique can be applied in many areas of image processing such as face recognition, composition and computer graphics, etc. Until now, many researches about face detection have been done, and applications in more complicated conditions are increasing. The existing technique proposed by Sirohey shows relatively good performance in image with cluttered background, but can apply only to image with one face and needs much computation time. The proposed method is designed to reduce complexity and be applied even in the image with several faces by introducing template matching as preprocess. The results show that the proposed method produces more correct detection rate and needs less computation time than the existing one.
