The purpose of this research is to investigate the effects of Lubric Learning Strategy Program, to solve problems of the Middle School Students' learning, on learning motivation, self-efficacy and self-regulation. The objects of this investigation was 60 students sampled from the first, second and third year students of Y Middle school in Seoul, which was divided equally -30 students each- into experimental group and control group. The progress covered 10 weeks period, a hour and half every week on Tuesdays and Thursdays. The conclusion derived from the results and discussion is as follows: First, the learning motivation of experimental group participated in the Lubric Learning Strategy Program to solve learning problems has changed quite meaningfully compared to the control group. It showed positive changes in all suborn ate variables such as class motivation, continuing motivation, intrinsic motivation, and extrinsic motivation. Second, the self-efficacy of experimental group participated in the Lubric Learning Strategy Program to solve learning problems has changed quite meaningfully compared to the control group. These results showed positive changes in subordinate variables such as preference level to subjects and self-control efficacy, though did not show notable changes in confidence area. However as confidence area doesn't really matter in total score, Lubric Learning Strategy Program is considered to have good influence in self-efficacy. Third, the self-regulation of experimental group participated in the Lubric Learning Strategy Program to solve learning problems has changed quite meaningfully compared to the control group. It showed positive changes in all subordinate variables such as self-control mode and inhibitory will mode. Fourth, the use on learning strategy of experimental group participated in the Lubric Learning Strategy Program to solve learning problems has changed quite meaningfully compared to the control group. These results showed positive changes in subordinate variables such as rehearsal, elaboration, organization and inspection, though did not show notable changes in schedule and control area. However, as the total score of use on learning strategy has changed prominently, Lubric Learning Strategy Program is considered to have good influence in use of learning strategy.

The world dairy industry has been driving their dairy policy on the basis of the self-supportihg principle. With progressing the GATT negotiation, the objective production amount has been reduced to maintain the optimum level, which decreasing the extra supply and over-stock before the U.R talks. The Oceania countries, where has the price competition capability, are continually increasing the milk production amount. Even through the USA is trying to increase their production amount with new export policy, the U.S.S.R collapse-down caused to decrease the milk production in world-wide basis. Because the U.S.S.R produced the highest amount of milk in the world. Moreover Europe Union countries, which recorded the half amount of dairy products in the world was decreasing their milk production. Therefore, about 4% of shortage is encountering at major dairy production countries in the standpoint of supply and demand. The drastic increasement of foreign dairy product import affects the domestic dairy industry with raw milk replacement and new dairy food demands creation since 1995, the initial period of free import system. Now, the domestic dairy industry are facing the inevitable problems such as the correction of producting and processing system. First of all, our dairy industry should resettle down the dairy production structure on the basis of self-supply of raw milk and offer the accurate dairy food informations. We still need to improve the raw milk quality. Also, more efforts are needed to have proper raw milk price policy. General domestic policies including the settlement of raw milk supply and demand, the reliability of inspection system in raw milk, ideal raw milk price system, centralization of raw milk collection, specially separated dairy organization should be improved legally in our dairy industry.

The camera cellular phone has a large portion of cellular phone market in recent year. The variety of a customer demand makes a fast model change and the spatial resolution is changed from VGA to multi-mega pixel. The 1.3 mega pixel (MP) camera cellular phone was first released into the Korean market in October 2003. The major cellular phone companies released a 2MP camera cellular phone that supports zoom function and a 2MP camera cellular phone is settled down with the Korea cellular phone market. It makes a keen competition in price and demands automation for phone camera module. There is an increasing requirement for the automatic assembly to correspond to a fast model change. The hard automation techniques that rely on dedicated manufacturing system are too inflexible to meet this requirement. Therefore in this study, this system is designed with the flexibility concept in order to cope with phone camera module change. The system has a same platform that has X-Y-Z motion or X-Z motion with ${\mu}m$order accuracy. It has a special gripper according to the type of a component to be put together. If the camera model changes, the gripper may be updated to fit for the camera module. The controller of this system acquires the data sets that have the information about the assembly part by the tray. This information is obtained ahead of an inspection step. The controller excludes an inferior part to be assembled by using this information to diminish the inferior goods. The assembly jig used in this system has a function of self adjustment that reduces the tact time and also diminish the inferior goods. Finally, the intelligent assembly system for phone camera module will be designed to get a flexibility to meet model change and a high productivity with a high reliability.

A self-assembled Al-bridged diiminopyridine-based ligand (3) was synthesized and characterized by FT-IR, ESI-MS and NMR spectroscopy. Electron spectral titrations were performed to confirm the formation of a novel trinuclear bis(imino)pyridyl iron(II) complex (4) upon addition of $FeCl_2$ into Al-bridged ligand 3 in methanol solution. Simultaneously, a typical bis(imino)pyridine-iron(II) complex (2) was synthesized and fully characterized. The X-ray crystal study of the iron(II) complex 2 disclosed a five-coordinate, distorted square-pyramidal structure with the tridentate N^N^N ligand and chlorides. The optimal molecular structure of 4 was obtained by means of molecular mechanics, which showed that each iron atom in the complex 4 is surrounded by two chlorides, a tridentate N^N^N ligand and one oxygen atom, supporting considerations about the possibility of six-coordinate geometry from MMAO or the ethylene access. A comparison of 4 with the reference 2 revealed a remarkable decrease of the catalytic activity and MMAO consumption (activity up to $0.41{\times}10^3\;kg\;{mol_{Fe}}^{-1}h^{-1}bar^{-1}$, Al/Fe = 650 for 4 and $7.02{\times}10^3\;kg\;{mol_{Fe}}^{-1}h^{-1}bar^{-1}$, Al/Fe = 1600 for 2).

To evaluate the accuracy of UAV photogrammetry for Hyangho coast, eastern coast of Korea, we conducted a field experiment wherein UAV photogrammetry test was repeated three times. Since the Haygho coast is located within a military reservation zone, it was necessary to obtain permission to gain access to the beach and to have sensitive aerial photographs showing military facilities inspected and cropped. The standard deviation of the UAV shooting position between the three tests was less than 1 m, but repeatability of footprint on the ground was low due to wind-driven variability of the UAV pose. Self-calibrating bundle adjustment(SCBA) of implementing non-metric camera calibration was failed in one test. In two tests, the vertical error was twice as large as the pixel size except for those areas that were subject to security inspection and cropping. Given the problems that can arise with regard to the repeatability of the shooting area as well as the possibility of failure with regard to SCBA, we strongly recommend that UAV photogrammetry in coastal areas needs to be repeated at least twice.

We investigated the foodservice management practices in various operation types of childcare centers in Asan, Chungnam Province, with the intention of improving the quality of foodservice and providing the basic information for establishing more effective and efficient foodservice model system. Self-completed questionnaires were collected from the directors of 174 child care centers. The statistical analysis was completed using SPSS Ver. 12.0 program. The followings are about the results of this study. Approximately 94.8% of the directors were women with the average age of 40.3. All of the investigated facilities executed foodservice; the facilities of 96.2% had been self-operated, 1.9% was contract-managed and the remaining 1.9% served delivered meal from outside. Only 20.0% of the investigated centers employed a dietitian. In most of the centers, meals were prepared in a conventional manner and approximately 85.3% of the centers are serving only snacks twice a day as a supplementary due to financial difficulties. Menu planner of the facilities, which have no dietitian was the director (35.8%) or the cook (25.7%). In most centers, the directors purchased the food materials (67.5%). Material inspection was done by the director (54.9%) or the cook (40.5%). However, home care centers did not inspect the food material. These results indicate that food service management guidelines need to be established by the facility type with the government control and financial support. Especially, dietitian employment and the efficient foodservice model system establishment are questions that confront us.

Objectives : The purpose of this study is to develop an apparatus which can take a facial image by self-operated capturing technique. The user can obtain one's facial image immediately after adjusting facial tilt and focusing distance. The system has been designed for classifying Sasang typology based on facial image. Methods : The system is composed of a Webcam, one-way glass mirror and mini LCD. The Webcam takes a facial image which is displayed on the mini LCD. Then the user can see and adjust to the right position in the real time through the image mirror-reflected from the mini LCD. The optical sensor is used to estimate the proper focusing distance. To verify the performance of the system, 11 characteristic points on the facial image are used and compared with high performance DSLR camera(D700) by applying the coefficient of variance and Bland-Altman Plot. Results : The developed system and D700 show enough agreement with the small coefficient of variance to analyse constitutional types with a facial im mage. However, the result of Bland-Altman plot shows that the width parameters have distortions owing to short focusing distance. Conclusions : The system is expected to be utilized on u-healthcare services for home environment after improving the distortion in the width parameters.
