  • To revise and develop a 'Model' Curriculum for training the middle standing professionals equipped with professional technology and theories at the spot of the library, such process were executed as research on bibliographic material and literature, utilization of examination of various questionnaires, interviews with middle standing librarians at the spot of the library, a review on the operational state of the Professor's Association of Library Science of Junior Colleges, some consultation with the Research & Deliberation Committee on Curriculums, etc., and to review the present department of library science at the two-year course's short-term colleges or institutes in foreign countries, Germany which is thought to be similar to our nation's situations and its level of economy and Singapore which is considered to be a newly emerging nation were looked into typically. In particular, since studies on the curriculums of the Library Science Dept. of colleges had already preceded, thereby the framework of the 'Model' curriculum was already achieved, however to review how well such framework is applied to the spot of education and give some improvement on that, some unrelistic findings of different subjects in consideration with reality, while comparing those curriculum schedules of each Library Science Dept. with the 'Model' curriculum schedule, were supplemented or revised to be fit to reality. For some supplementing or revising proposals on the pre studied 'Model' curriculum, some tentative plans which focussed on each field respectively and some tentative plans which focussed on cultural subjects, required major subjects and elective subjects were suggested in duality to be referred to. On such a process of forming a harmony of educational theories and practice, it was planned to revise and develop curriculum in a sense emphasizing on practical exercise, and tried not to neglect on each of the fields of the curriculum centered on the areas of materials organization, linguistics, information resource, information science, library organization, & administration, etc. The study on curriculums should be performed flexible to be applied to the accelerating transition of sciences, and be good examples in instruction.

  • Objective: The purpose of this in vitro study was to examine the effects of fluoridated, casein phosphopeptide-amorphous calcium phosphate complex (CPP-ACP)-containing, and functionalized ${\beta}$-tricalcium phosphate (fTCP)-containing toothpastes on remineralization of white spot lesions (WSLs) by using Quantitative light-induced fluorescence (QLF-D) Biluminator$^{TM}$ 2. Methods: Forty-eight premolars, extracted for orthodontic reasons from 12 patients, with artificially induced WSLs were randomly and equally assigned to four treatment groups: fluoride (1,000 ppm), CPP-ACP, fTCP (with sodium fluoride), and control (deionized water) groups. Specimens were treated twice daily for 2 weeks and stored in saliva solution (1:1 mixture of artificial and human stimulated saliva) otherwise. QLF-D Biluminator$^{TM}$ 2 was used to measure changes in fluorescence, indicating alterations in the mineral contents of the WSLs, immediately before and after the 2 weeks of treatment. Results: Fluorescence greatly increased in the fTCP and CPP-ACP groups compared with the fluoride and control groups, which did not show significant differences. Conclusions: fTCP- and CPP-ACP-containing toothpastes seem to be more effective in reducing WSLs than 1,000-ppm fluoride-containing toothpastes.

  • BACKGROUND/OBJECTIVES: To date, sodium intake has been evaluated based on spot urine instead of 24-hour (hr) urine collection. Nevertheless, the optimal method for assessing daily sodium intake remains unclear. SUBJECTS/METHODS: Fifteen male (age 32.7 ± 6.5 years) participants were offered 3 meals with a total of 9-10 g salt over 24 hours, and 24-hr urine was collected from the second-void urine of the first day to the first-void urine of the second day. Twenty-four-hr urinary sodium (24UNa) was estimated using Tanaka's equation and the Korean formula, and spot urine Na, potassium (K), chloride (Cl), urea nitrogen (UN), creatinine (Cr), specific gravity (SG) and osmolality (Osm) were measured. The ratios of urinary Na to other parameters were calculated, and correlations with total measured 24UNa were identified. RESULTS: Average 24-hr urine volume was 1,403 ± 475 mL, and measured 24UNa was 143.9 ± 42.1 mEq (range, 87.1-239.4 mEq). Measured 24UNa was significantly correlated with urinary Na/UN (r = 0.560, P < 0.01), urinary Na/Osm (r = 0.510, P < 0.01), urinary Na/Cr (r = 0.392, P < 0.01), urinary Na/K (r = 0.290, P < 0.01), 24UNa estimated using Tanaka's equation (r = 0.452, P < 0.01) and the Korean formula (r = 0.414, P < 0.01), age (r = 0.548, P < 0.01), weight (r = 0.497, P < 0.01), and height (r = 0.393, P < 0.01) in all spot urine samples. Estimated 24UNa based on the second-void spot urine of the first day tended to be more closely correlated with measured 24UNa than were estimates from the other spot urine samples. The significant parameters correlated with the second-void urine of the first day were urinary Na/K (r = 0.647, P < 0.01), urinary Na/Cr (r = 0.558, P < 0.05), and estimated 24UNa using Tanaka's equation (r = 0.616, P < 0.05) and the Korean formula (r = 0.588, P < 0.05). CONCLUSIONS: Second-void urine is more reliable than first-void urine for estimating 24UNa. Urinary Na/K in the second-void urine on the first day is significantly correlated with 24UNa. Further studies are needed to establish the most reliable index and the optimal time of urine sampling for predicting 24UNa.

  • In this paper, intelligent compaction (IC) technology and the earthwork quality control specifications based on IC were analyzed, and the field study was conducted to investigate the relationship between the representative IC value CMV (Compaction Meter Value) and spot test results (plate bearing test and field density test). As the number of roller passes increased, both the CMV and spot test results increased. However, point-by-point comparison between CMV and spot test results yielded poor quality correlations; this is because the ununiform stiffness of the underlying layer and the moisture content of the lift layer affected the CMV and spot test results, respectively. Most international specifications related to IC requires knowledge of the IC values and their relationships with the soil properties obtained by the traditional spot tests. Therefore, for the successful implementation of intelligent compaction technology into earthwork construction practice, the number of roller passes as well as the lift thickness and the moisture content of the soil should be carefully considered.

  • This survey is related to the status of education for environmental managers, who are taking charge of pollution control untilities, and its analyses. This survey is also discussing the improvements of educational course for the trainees, who have already been educated in environmental background as well as its problems. The 45% of in-service trainees were those who had graduated more than a junior college. But under the 50% of them were those who had school careers of less than a high a high school, which means that the trainees have trouble in acquiring the professional knowledges on environmental educations such as the lectures and the practice educations. All over the country, 46 junior colleges, and 65 universities which have a environmental education program, have produced the graduates who major in the environment. Therefore, it is demanded that they should be properly treated. In this research work, it is shown that the 76% of environmental managers have no certificate of environmental study. It is thought that this has resulted from the released environmental law; the untilities of the first and second grade need a manager with a certificate related with environment, the third grade utilities only need a manager with a non-specified certificate related with environment or a manager with more than 3 years environmental practice careers, the fourth and fifth grade utilities do not need the certificate related to environment. In view of relation between environment pollutions and the management of environmental utilities, it is thought that present environmental laws should be improved to be strict. The fact that the differences in regions or utilities are not considered in the contents of texts, has reduced the efficiency of education. Therefore, it is needed that the experts and the in-service managers should take part in the development of the text. In this survey, the more than 20% of trainees have negative opinions about the result of this education, which means that overall the environmental practice education should be reconsidered. In the educational methodology, more than 50% of trainees have the opinion that they want spot speciations, the audio-visual educations and the practice. Therefore, it is demaned that the subjects, syllabus, and the allotment of time ect, should be reorganized for the more practical education.

  • This study was conducted under the theory of hermitage ever built from buddhist belief. Directing to hermitages within temples of Korea Jogye Order, we focused on the layout correspondence relationship among them. and 161 hermitages were the first object of the investigation. For the accomplishment of the research purpose, the general epitome and spatial specification through various literature studies, on-the-spot survey and personal communications with a lot of priests were made. As one of the basic surveys, the foundation year were thoroughly investigated, followed by the form of building, main buddha and hermitage name. The results obtained were summarized as follows : Forty five hermitages which are equivalent to twenty eight percent of total hermitages within the parish-level temples of Korea Jogye Order, were built in shilla Dynasty and twenty hermitages that are 12.4 percent of the total were constructed in Koryo Dynasty and thirty seven percent of the total were founded during both of dynasties. This fact makes us to consider that many of hermitages in those days were constructed with the simultaneity of principal temple foundation which means hermitage had responded the spirit of the times. Every hermitage has its main Buddha and this thing happened that each hermitage enshrines its main Buddha according to the thought which was developed with the Buddhism expansion and sutra that is in accordance with their own intention. .Basically a capital temple has differed in its central sanctum in accordance with resourceful sutra, and, at the same time, twenty seven in avatamsk sectenshrine for Sakyamuni as their sanction and eight for the Merciful Goddess and 42.7 percent for Chajang's hermitages. The name of hermitage not only represents its symbol but comprises the characteristic meaning of ascetic practice. 31.7 percent of the hermitages studies was found to have the names of relating to 'ascetic practice' or 'thought' followed by the 'nature' or 'environment' to 21.7 percent.

  • The introduction of osseointegrated dental implants in dentistry brought about a new era in everyday dental practice. For the past 50 years, prosthetic restoration with implant-supported prosthesis has developed into a viable and predictable treatment option. Alongside the increasing use of dental implants is the occurrence of many complications during implant placement (surgery), in the mechanical or prosthetic problem, and in the biological aspect. In particular, abutment or screw fracture as one of the mechanical complications can put the dentist in a tight spot in a clinical situation. It is hard to remove the fractured abutment and screw to restore it properly. Therefore, it is very important that clinicians consider possible complications in advance and make an appropriate treatment plan. We discuss cases of abutment fracture and mechanical/prosthetic complications together with the causes and solutions.
