The present study was performed to evaluate the effect of tetracycline - HCl on the change of implant surface microstructure according to application time. Implants with pure titanium machined surface and titanium plasma-sprayed surface were utilized. Implant surface was rubbed with 50mg/ml tetracycline - HCl solution for 1 min., $1\frac{1}{2}\;min$., 2 min., $2\frac{1}{2}\;min$. and 3min. respectively in the test group and with saline for 1 min. in the control group. Then, the specimens were processed for scanning electron microscopic observation. The following results were obtained. 1. Pure titanium machined surfaces conditioned with saline for 1 min., showed a few shallow grooves and ridges and were less irregular. 2. Pure titanium machined surfaces conditioned with 50mg/ml tetracycline - HCl solution showed more irregular and corrosive surfaces compared to the control group irrespective of the application time of tetracycline - HCl solution. 3. Titanium plasma-sprayed surfaces conditioned with saline for 1 min., were deposited with round amorphous particles and showed round or irregular pores that can be connected to each other. 4. The irregularity of titanium plasma-sprayed surfaces conditioned with 50mg/ml tetracycline - HCl solution was lessened and the flattened areas were wider relative to the application time of tetracycline - HCl solution. 5. Titanium plasma-sprayed surfaces conditioned with tetracycline - HCl solution for 1 min. and $1\frac{1}{2}\;min$. were very similar to that of the control group, but the surfaces conditioned for 2 min., $2\frac{1}{2}\; min$. and 3 min. were changed. In conclusion, pure titanium machined surfaces were changed irrespective of the application time of tetracycline - HCl solution. And titanium plasma-sprayed surfaces conditioned with tetracycline - HCl solution began to be changed from $1\frac{1}{2}\;min$. This results will be applicable to the regenerative procedures for peri-implantitis treatment.

The purpose of this study was to identify levels of cognitive distortion, depression, and gambling severity and to identify the influences of cognitive distortion and depression on gambling severity in Koreans with a gambling disorder. Methods: The participants in this study were 150 Koreans with a gambling disorder. Data were collected using self-report structured questionnaires which included individual characteristics, the Gambling Related Cognitions Scale, the Center for the Epidemiologic Studies Depression, and the Problem Gambling Severity Index. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson`s correlation coefficients, and multiple regression. Results: Gambling severity had a significant correlation with gambling related cognitions scale-perceived inability to stop gambling (r=.29, p<.001) and depression (r=.34, p<.001). Among predictors, depression (β=.24, p=.035) and type of housing tenure (β=.26, p=.022) had statistically significant influence on gambling severity. The explanatory power of this regression model was 17.0% (F=3.72, p=.003). Conclusion: The findings from this study indicate that interventions to decrease depression are essential to decrease the gambling severity of Koreans with gambling disorder.

홍성실(Sung-Sil Hong),홍정아(Jung-Ah Hong),전원희(Won-Hee Jun) 한국콘텐츠학회 2013 한국콘텐츠학회논문지 Vol.13 No.6

본 연구는 간호학생의 영성과 임상실습 스트레스 정도를 평가하고 이들 간의 관계를 파악하여 간호학생들의 영성증진과 임상실습 스트레스 중재방안으로 영성의 활용가능성을 확인하고자 시도하였다. 2개 대학의 간호학생 203명을 편의 추출하여 자가 보고식 설문지를 사용하여 자료를 수집하였다. 연구결과, 본 연구 대상자들의 영성은 5점 만점에 3.18점, 임상실습스트레스는 5점 만점에 3.42점으로 중간이상의 수준이었다. 하위영역별로는 영성의 경우 ‘삶의 의미와 목적’이 가장 높았고, 임상실습 스트레스에서는 ‘실습교육환경’에 대한 스트레스가 가장 높게 나타났다. 일반적 특성에 따른 차이에서는 영성은 종교와 전공만족도에 따라, 임상실습 스트레스는 성별과 전공만족도에 따라 유의한 차이를 보였다. 영성과 임상실습 스트레스는 유의한 부적상관관계가 있었다. 결론적으로, 간호학생들의 임상실습 스트레스를 감소시키기 위해서는 영성증진을 위한 교육프로그램 개발과 이를 효과적으로 교육과정에 접목시킬 수 있는 방안을 구축할 필요가 있다. The purpose of this study was to investigate the level of spirituality and stress of clinical practice and to identify the relationship of variables among nursing students. Data were collected from 203 nursing students using self-report questionnaire composed of demographic characteristics and two scales including spirituality and stress of clinical practice. Data were analyzed by frequencies, t-test, ANOVA, Pearson‘s correlation coefficients using the SPSS program. The mean score for spirituality and stress of clinical practice were above medium level, with the value of 3.18 and 3.42 out of 5 respectively. There were significant mean differences in spirituality according to religion and satisfaction on major while those in stress of clinical practice according to sex and satisfaction on major. Significant negative correlation between spirituality and stress of clinical practice was found. In conclusion, to reduce clinical stress in nursing students, it is necessary to develop and apply educational program for spiritual improvement.

Literally, the mean of Tae-gye is highest brook. And on the basis of the acupuncture theory, Tae-gye point is the Soo earth point and source point of the Kidney Channel as well. In addition, Tae-gye point is one of the Yang-Returning Nine points. We were trying to study bibliographically on the Tae-gye point because Tae-gye point can be used very broadly across the symptoms in the theoretical aspect described above. As a results, we found out that according to the classical books of acupuncture, Tae-gye point is entering point of the Meridian Water as a source point and can be used at both Kidney-Sufficient Syndrom and Kidney-Deficient Syndrom. And Tae-gye can be applied to the disease of kidney or bladder that is urogenital symtoms, Also, Tae-gye is an useful option of tooth-ache, asthma, indigestion, constipation, edema etc whose cause is related with decrease of Kidney ki.
