Maximum voluntary isometric bite force was recorded at the incisors and at the molars in 111 korean young abults, 56 males and 55 females aged 18-25 years. the relationships in dite force and facial skeleton were studied by means of simple linear correlation analyses. There was not sighificant correlations between bite force and facial morphology & bimension.

Purpose: The study was performed to compare the content of their jobs of the nurses working in the free elderly home with free nursing home in the whole country. Method: The subjects consisted of 138 nurses working in elderly home and nursing home. The data was collected from Jan. 1st to Feb. 22th 2005 using a structured questionnaire that included general characteristics, content of tasks which the nurse dose every day, health program, perceived job satisfaction and pay satisfaction scale. The collected data was analyzed by the SPSS(version 11.5) program including descriptive statistics, x^(2)-test. Result: On the nurses in the free elderly homes and nursing homes, there were many patient diagnosing hypertension, arthritis and dementia. Recently the death rate in elderly home and nursing home was highly increased. The mean period of nurses working in elderly home and nursing home were 3.75 years and 2.76 years. Experience of staying with the elderly was 70.9% on nurses working in elderly home. and 73.2% on nurses working in nursing home. Daily allotment of the nurses working in elderly home and nursing home were health assessment, medication care and eating care. The highest priority rank of nursing care of the nurse working in elderly home and nursing home was health assessment. Mean number of the patient in daily nursing care of the nurse residing in elderly home and nursing home was referral to hospital on 1-5persons/day and then transfer care on 1-6persons/day. The highest health care program was an exercise program. Conclusion: The resident nurses in the free elderly homes and nursing homes have had various types of tasks, and for their security a system for job satisfaction was needed.

The effect of ozone on the formation and the removal of disinfection byproducts(DBPs) of chlorination process was studied to elucidate the performance of water treatment process. The samples of raw water, prechlorination process, and preozonation process were analyzed quantitatively according to the Standard Methods for the Examination of drinking water. As a result, most of total trihalomethanes(THMs) which were formed in prechlorine treatment process was not removed in the preozonation process. Most of haloacetic acids(HAAs), haloacetonitriles(HANs), and chloral hydrate(CH) was removed in sedimentation and biological activated carbon(BAC) filtration processes. However, DBPs were increased more or less by postchlorine step. In particular, the formation of THMs and HAAs depends on ozone more than chlorine, but, the formation of HANs and CH depends on chlorine more than ozone. The seasonal variation of DBPs concentration for the year needs to be investigated to study the temperature effect because DBPs strongly depend on temperature among various efficient factors.

About twenty years ago the computer was introduced into orthodontic, but not in clinics because it was inconvenient in cost, size, capacity and operation. But recent advances in the technology of electronics have produced a personal computer which is suitable for use in clinics. We have developed useful program for cephalometric Ax, model analysis and patient management. The computer program greatly aided in saving time & effort and performed well in the management & searching for patient data. But further studies about tree dimensional analysis, S.T.O. and derivation of automatic treatment planning from analysis are needed.

본 연구는 폐석재와 석분을 사용하여 친환경적인 식생블럭 제품을 개발하기 위하여 폐석재의 입경과 석분의 첨가량을 각각 3종류씩 총 9종류의 식생블럭에 대하여 단위중량, 공극율, 투수량, 압축강도, 쪼갬인장강도, 휨강도, 내산성, 알카리농도에 대하여 구명하였다. 단위중량, 강도, 내산성은 골재의 입경이 작을수록 석분의 혼입량이 많을수록 크게 나타났으며, 공극율과 투수량은 작게 나타났다. 강도는 중성화 처리 유무에 따라 4∼5% 정도의 미소한 차이가 나타났다. 알카리 농도는 중성화 약품처리, 수중용출, 야외폭로 순으로 효과가 크게 나타났으며, 이는 식생블럭의 중성화 방법 선택에 매우 중요한 내용이라 할 수 있다. 또한, 식생상태는 공극율과 골재의 입경이 큰 식생블럭이 생육에 유리한 것으로 나타났다. This study was performed to develop the environment-friendly plantable block and to evaluate unit weight, void ratio, permeability, strength, acid-resistance and value of pH by the change of the grading of waste stone and the addition amount of stone dust. The unit weight, strength, acid-resistance is increased with small size of waste stone with increase of the addition amount of stone dust. But, the void ratio and permeability is decreased. The strength of neutral plantable block is decreased approximately 4-5% than that of the normal plantable block. The decreased effect of pH increased in order to neutral treatment, underwater leaching and field exposure. It is very important contents in neutral method selection of plantable block. Also, the planting state is grown rapidly with increase of the void ratio and of the waste stone size, approximately.
