Purpose: The purpose of this study was to identify the types of violence experienced by small and medium sized hospital nurses. Methods: Data were collected from March 1 to 30, 2017, using self-report questionnaires. Responses from 87 nurses were analyzed using descriptive statistics, $x^2$ test, Fisher's exact test, t-test. Results: The majority of the respondents experienced violence from patients (60.2%), visitors (25.5%), doctors (12.2%), and other staffs (2.0%). Verbal violence (80.5%) and physical threats (74.7%) were more frequent than physical violence (25.3%). Violence occurred throughout the hospital. However, verbal violence ($x^2=20.85$, p=.005) and physical threat ($x^2=20.80$, p=.006) were statistically significant according to the department. Violence occurred most frequently in surgical ward, followed by artificial kidney room, emergency room, and outpatient department. Conclusion: Most nurses are exposed to frequent violence. These results suggest that hospital should improve the respective organizational cultures and develop promotional programs and administrative policies to prevent violence. Also, hospitals should develop of violence intervention policies and education programs and counseling programs for nurses.

The purpose of this study was to examine the influence of canal irrigants and smear layer on the property of apical seal. Fourty-five canals from human teeth were randomly selected and divided into 5 groups according to the irrigants used in conjunction with instrumentation. The irrigants were RC-prep in combination with Naocl, Citric acid, Naocl, Naocl in combination with $H_2O_2$, and normal saline solution. After instrumention and dry the canal with paper point, the canals were obturated by lateral condensation of Zinc-oxide eugenol sealer and gutta percha cone. All the specimens were immersed in 2% methylene blue dye solution for 7 days and the depth of dye penetration into the canals was evaluated by macros cope. The following results were obtained. 1. All the canals experimented showed varying degree of dye penetration. 2. There was no significant difference in depth of dye penetration between the groups known to be effective and ineffective in the removal of the smear layer. 3. The canals irrigated with NaOCl alone showed the highest dye penetration and mean leakage was 7.7 mm. 4. In the canals irrigated with RC-prep in combination with Naocl and citric acid, the mean dye penetration was 5.5 mm and 4.8 mm respectively, and the canals irrigated with NaOCl in combination with $H_2O_2$ and normal saline solution revealed mean dye penetration of 3.9 mm.

Purpose: This study was measured to the bone mineral density(BMD) and biochemical bone markers in young women in order to identify the relationship between bone mineral density and biochemical bone markers. Methods: Forty two healthy young women were enrolled. BMD were checked Dual Energy X-ray Absorptiometry and biochemical bone markers were checked ELSA-OSTEO(CIS bio international, France)analyzed kit, Pyrilinks-D(Metra Biosystems Inc., U.S.A)analyzed kit. Data were analyzed with frequencies, percentages, means, and Pearson correlation coefficients. Results: 1) Young women forearm(radius & ulnar) BMD was $0.55g/cm^2$, lumbar($1{\sim}4$) BMD was $0.92g/cm^2$, neck of femur BMD was $0.75g/cm^2$, trochanter of femur BMD was $0.61g/cm^2$, ward's triangle of femur BMD was $0.68g/cm^2$. In biochemical bone marker, Osteocalcin was 21.94ng/ml, Deoxypyridinoline was 11.94nmol/nmolCr. 2) There was no significant correlation between BMD and biochemical bone markers. Conclusion: Results not indicated association between bone mineral density and biochemical markers. As seen in the small sample, future research on BMD and biochemical markers need to studies to the large sample.

This study was to evaluate the cytotoxic effect of three root canal disinfectants (formocresol, camphorated phenol and eugenol) and ten root canal sealers(Cavitec, Hypo-cal, Vitapex, AH26, Canals, Mynol, $N_2$, $N_2$-Medical, Z. O. E. and Calvital) in vitro. The experiments were performed in four differrent modes. In the first and second experiment, the "long-distance" cytotoxicity of three root canal disinfectants were tested on L cells. In the third exeriment, ten root canal sealers were tested for cytotoxicity by means of the tissue culture-agar overlay method immediately, 4 and 24 hours after the experiment. In the fourth experiment, the study with radioactively labeled L cells were employed to determine the relative cytotoxicity of ten root canal sealers. The results were as follows; 1. Every vapors from disinfectants showed more or less cytotoxicity. Of the three disinfectats, formocresol appeared to be the highest cytotoxic effect and camphorated phenol was the lowest. 2. Root canal sealers tested in tbis study showed cytotoxicity at every stage of time intervals. 3. The highest cytotoxic effect was freshly mixed $N_2$ meaical and $N_2$ also revealed the highest cytotoxic effect after 4 or 24 hours among these materials. Vitapex was found the lowest cytotoxic effect at all experimental stage. 4. Root canal sealers except N2 and Mynol showed cytotoxic effect were decreased cytotoxicity according to the time elapsed.

Sixty-nine articles were reviewed to understand the depression in patients with rheumatoid arthritis. Among these articles, forty seven were the studies that dealt with depression in rheumatoid disease, nineteen studied the depression in patients with other chronic disease or in normals, and three were the studies that compared the depression in the patients with rheumatic disease and in the other subjects. Specifically, the articles were analyzed (1) to determine whether the patients with rheumatic arthritis were more depressed than normal population or subjects with other chronic diseases ; (2) to test whether the measurement problems exit ; (3) to identify the disease related, personal, psychologic, and demographic variables to affect the depression and (4) to identify the nursing interventions which improve the depression in rheumatoid arthritis. Based upon these results, some suggestion were made for future research and practice.

This study was conducted to identify the characteristics of fatigue and its influencing factors in patients having chronic arthritis. The subjects of this study were 120 patients who visited a Rheumatis Center of H University Hospital. Data were collected from Aug. 9, 1997 to Feb. 5, 1998. For analysing data, SPSS/Win was used for descriptive statistics & Pearson's correlation coefficient, and Lisrel 8.0 was for path analysis. The findings were as follows : 1. Mean score of subjective fatigue was 5.36 and it means moderate degree of fatigue. 2. Fatigue showed positive relationship with pain & depression, and it showed negative relationship with ADL & self efficacy. 3. Fatigue was influenced by pain and depression. and was not influenced by ADL and self efficacy directly. But ADL and self efficacy influenced on fatigue through pain and depression indirectly. According to this findings. the significant influencing factors of fatigue were pain and depression, therefore the development of nursing intervention for relieving pain and depression would be needed.

64 multi-rooted teeth (198 canals) were tested in vitro to evaluate the apical seal produced by the single cone filling and lateral condensation with sealer and without sealer. The obturated teeth were immersed in India ink, decalcified, and cleared. The degree of ink penetrated into the canal provided a measure of the apical seal. The results were as follows: 1. The lateral condensation with sealer provided statically less apical leakage than the other obturating techniques used in this study. 2. The single cone filling provided good apical sealing. 3. The lateral condensation without sealer provided most apical leakage than any other techniques used in this study. 4. The degree of apical leakage was not related to the visual appearence of the adaptation of the gutta percha filling in cleared teeth.
