Second, the necessity of adopting subject divisional plan is to secure enough subject librarians and large space These necessities must be fulfilled prior to adopting the subject divisional plan. Third subject divisional plan model for efficient reference service of university library is 'wide-area subject divisional plan model'. 1) In the case of central library, the space model of wide-area subject divisional plan is programmed as undergraduate library for the undergraduate students. And each subject libraries is operated as research library for the professors and graduate students. 2) In central library, the collection model of wide-area subject divisional plan is practiced as offering reference and general education centered data for undergraduate students 'study. And each subject libraries is furnished with research papers, recent journals, and various major-related data. 3) The human resource model of wide-area subject divisional plan is applicated by arranging appropriate librarians at the right place. In the case of central library, the reference librarians and librarians who educate the users and take charge of function are set in to help undergraduate students with their study. Subject library needs to secure subject librarians, librarians who take charge of function, and graduate students who are related to the subject as student assistant. Then it is possible to discriminate reference service by subjects and users.

The purpose of this study was to investigate the relationship between physical activity participation habits, physical fitness level, and academic performance among the Reserve Military Training Corps (ROTC). Participants in the current study were 71 ROTCs from J University. Physical activity participation was investigated using the Global Physical Activity Questionnaire (GPAQ), and the level of physical fitness was measured by health-related physical fitness evaluation. For academic performance, university grade data (GPA) was approved by the head of the relevant school district, and the data were collected with the consent of the participants, and each data was analyzed. The correlation between physical activity participation habits, physical fitness level, and GPA was analyzed, and GPA by physical fitness level were compared. This study found that there was no statistically significant correlation between physical activity participation and academic performance. Otherwise, there was a statistically significant correlation between major subjects and total physical fitness score, cardiorespiratory fitness, muscular endurance, flexibility, and body composition. By the level of physical fitness, the ROTCs in the high-physical fitness group showed statistically significantly higher academic performance than the ROTCs in the low-physical fitness group. In addition, low level of physical fitness ROTC group was lower than the other. In conclusion, ROTCs with a high physical fitness level had a positive effect on improving learning ability compared to those who did not. By recommending an autonomous but systematic exercise training program, it is suggested to improve the physical strength of ROTCs and to cultivate excellent future military officers.

AVO and complex trace analyses mainly used to characterize natural gas reservoir were tested in this paper for a possible application to detection of major geological discontinuities such as fracture zones. The test data used in this study were calculated by utilizing a viscoelastic numerical program which was based on the generalized Maxwell body for a horizontal fracture model. In AVO analysis of a horizontal fracture zone, p-wave reflection appears to be variant depending upon the acoustic-impedence contrast and the offset distance. The fracture zone is also effectively clarified both in gradient stack and range-limited stack in which fracture zone reflection is attenuated with the increasing offset distance. In complex attribute plots (instantaneous amplitude, frequency, and phase), the top and bottom of the fracture Tone are characterized by a zone of strong amplitudes and an event of the same phase. Low frequency characteristics appear at the fracture zone and the underneath. Amplitude attenuation and waveform dispersion are dependent on Q-contrast between the fracture zone and the surrounding media. They were properly compensated by optimum inverse Q-filtering.

In this study, 340 Korean women were surveyed to analyze the impact of the type of sunscreen and use status on the satisfaction of products and resale. Studies have shown that indoor activity is higher than outdoor activity, and both simple and complex sunscreen is often used to compensate for skin tone. Out of single sunscreen, sun cream was used and air cushion was used a lot. Although product usability and UV protection indices were important factors in purchasing, 30% experienced side effects while product satisfaction and willingness to repurchase were high. The recognition of safety, Effectiveness, convenience, usability, satisfaction, and repurchase were all higher than that of composite UV-blocking products, and among subcomponents of product usage recognition, the level of convenience, efficacy, usability, and safety affected satisfaction and repurchase in order. Consequently, the perception of simple UV protection products was higher when using products for UV protection, and its convenience had a significant impact on satisfaction and resale.

The Carved Buddhist Triad on Rock-cliff in Sinarnri (Treasure No. 680) consists of biotite granodiorite, which were positively carved on fore and west planes of four subvertical cliffs by two joint sets of NE-SW and NNW-SSE directions. The cliffs are $N50^{\circ}E\;85^{\circ}SE$ in fore plane, $N25^{\circ}W\;90^{\circ}$ in west plane, $N40{\sim}50^{\circ}E\; 82{\sim}85^{\circ}NW$, back plane, $N20^{\circ}W\;75^{\circ}SW$ in east plane, which are parallel to two joint sets of NE-SW and NNW-SSE directions in geology around it. The chemical index of alteration ranges 60.3 to 62.0 from the major elements in the rock that was weathered into producing kaolin minerals from alteration of feldspars and biotite. The Buddhist image has been deteriorated into joints, brown rusts, discolorations and granular disintegrations by such deterioration causes as deformation, moisture, temperature variation and microorganic living. The moisture, which leaks from groundwater in the rock, dissolve to decompose minerals.
