본 논문에서는 1991년 이후 중간 강도 이상의 엘니뇨가 발생한 해의 고랭지배추의 단위면적당 생산량의 변화를 비교 분석하였다. 엘니뇨가 발생한 해 (n=12)의 고랭지배추의 전국 평균 생산량 (3,444±384kg 10a-1)은 미 발생한 해 (n=14)의 생산량 (3,722±277kg 10a-1)보다 적었으며, 통계적으로도 유의하였다 (t=2.140, p=0.042). 또한, 엘니뇨가 종료한 해의 고랭지배추의 전국 평균 생산량은 엘니뇨가 시작한 해와 엘니뇨가 미 발생한 해보다 낮은 경향을 보였고, 이 또한 통계적으로 유의한 것으로 분석되었다(df=2, f=3.874, p=0.035). 이것은 고랭지 배추 재배기간의 저온, 일조부족, 강수량 증가 현상이 1차적 원인으로 사료되나, 앞으로 엘니뇨 발생에 따른 악기상 등 각종 농업환경 변화와 고랭지배추의 생산성의 관계 등 추가 연구가 필요하다.

Objectives: This study was performed to provide a reference base to establish foundation for education about dental hygienist-related medical law and introduction of the system. Methods: A survey was conducted on 210 dental hygienists working at a dental clinic/ hospital in Jeollado. Data were analysed through chi-square test, one-way ANOVA, independent t-test, and Pearson's correlation analysis using SPSS 21.0 program. The study instruments included general characteristics of the subjects, knowledge on laws related to dental hygiene, attitude towards dental hygienist-related medical laws, level of understanding of medical related laws, and medical dispute educational hours. Results: The knowledge of dental hygienist-related medical law was high in dental hygienists aged 25 years and younger and with less than 3 years of clinical experience (p<0.05). The attitude towards the law was low in age of younger than 25 years, a three year college degree, a job position as a staff member, more than 5 years of work experience at present work place, and less than 3 years of clinical experience (p<0.05). Understanding of medical related laws was high in clinical staff members and with less than 3 years of clinical experience (p<0.05). Educational needs for medical dispute prevention was high in a job position as a staff member, low level of attitude towards dental hygienist-related medical law, and no attainment of education on medical dispute (p<0.05). Conclusions: The above results demonstrate that education and public relations about laws related with dental hygiene practice are essential. It is imperative to establish a systematic and bureaucratic legal system to prevent dental malpractice.

Background: Despite mixed survival data, the utilization of contralateral prophylactic mastectomy (CPM) for the prevention of a contralateral breast cancer (CBC) has increased significantly over the last 15 years, especially among women less than 40. We set out to look at our own experience with CPM, focusing on outcomes in women less than 40, the sub-population with the highest cumulative lifetime risk of developing CBC. With an extended follow-up, we hoped to demonstrate differences in the long-term disease free survival (DFS) and overall survival (OS) among groups who underwent the procedure (CPM) versus those that did not (NCPM). Materials and Methods: We performed a retrospective review of all breast cancer patients less than age 40 diagnosed at Mount Sinai Medical Center between January 1, 1980 and December 31, 2010 (n=481). Among these patients, 42 were identified as having undergone CPM, while 195 were confirmed as being CPM-free during the observation period. A univariate and multivariate analyses were performed. Results: The CPM group had a significantly higher percentage of patients who were diagnosed between 2000 and 2010 (95.2% vs 40%, p=0.0001). The CPM group had significantly smaller tumors (0-2cm.: 41.7% vs 24.8%, p=0.04). Among the entire group of patients, the overall five- and 10-year DFS were 81.3% and 73.3%, respectively. CPM was significantly associated [HR 2.35 (1.02, 5.41); p=0.046] with 10-year OS, although a similar effect was not observed for five-year OS. Conclusions: We found that CPM has increased dramatically over the last 15 years, especially among white women with locally advanced disease. In patients less than 40, who are thought to be at greatest cumulative risk of secondary breast cancer, CPM provided an OS advantage, regardless of genetics, tumor or patient characteristics, and which was only seen after 10 years of follow-up.

Purpose: This study was to describe the uncertainty, depression, physical symptom, and family support among patients undergoing dialysis. Further, the factors that impact uncertainty were also examined. Methods: A convenience sample of 145 patients who received dialysis was selected. A descriptive correlation study was conducted. Data were collected using structured questionnaires and the collected data were analyzed using descriptive statistics and multiple regression analysis. Results: The patient who received more than five years of dialysis reported higher levels on inconsistency of uncertainty than patient with less than five years. These latter patients' reported uncertainty was positively correlated with depression, whereas, patients family support was correlated with uncertainty. The group's uncertainty with less than five years of dialysis explained about 13% of the variance. In contrast, variables of education level, family support, and monthly income were predictors of uncertainty and explained 33% of the variation. Conclusion: These results can provide for nursing intervention to facilitate reduction of uncertainty. To provide dialysis period-sensitive nursing intervention for uncertainty among dialysis patient, depression should be considered below five years. While factors such as education level, family support, and monthly income should be taken into account over five years.

Background: To determine survival times of cervical cancer patients with bone metastasis related to the effect of age at the time of cervical cancer diagnosis, we performed the retrospectively analytical study. Methods: A total of 68 cervical cancer patients with bone metastasis were treated at a single hospital, during January 1998 to December 2010. Fifty-two medical records were identified and collected, the remaining sixteen medical records were not found. Main outcome measures were patient characteristics, clinical information, duration from cervical cancer diagnosis to bone metastasis diagnosis, survival time after bone metastasis and overall survival time. Results: Among fifty-two cervical cancer patients with bone metastasis, there were 13 patients who were less than 45 years old, and 39 patients were 45 years old or more at the time of cervical cancer diagnosis. The younger group had less median overall survival than the older group, with a statistically significant difference (21 months, 95% CI 19.93-22.06; 34 months, 95% CI 23.27-44.72, p = 0.021). However, they were comparable in the duration from cervical cancer diagnosis to bone metastasis diagnosis and the survival time after bone metastasis. Conclusion: Young patients with bone metastasis aged less than 45 years old at the time of cervical cancer diagnosis have a poorer prognosis than the elderly patients. Impact: To improve survival and quality of life, more intensive and novel multimodal treatments at the time of cervical cancer diagnosis should be considered in patients less than forty-five years, who can tolerate the side effects better.

This survey was conducted to investigated the status of nutritional consumption and relationship of nutrition of patients in hospitals from 1998.9.1 to 1998.9.10. Calorie intake of male patients was lower than RDA but that of female patients were higher than RDA except female younger than 64 years old. Protein intake of male patients was 130% higher than RDA, and that of female patients was 150% more than RDA. Calcium intake was lower than RDA in male patients but higher than RDA in female patients except older than 75 years. Iron intake was higher than RDA in all patients except in male patients older than 75 years. while vitamin B$_1$and vitamin C intake was higher than RDA in all patients but vitamin A and niacin intake was lower than RDA. The rich patients intake enough iron through animal foods and stabilized patients intake vitamin B$_2$ more than RDA. All patients were recognized the importance of protein and vegetable for health and they were recognized also careful choosing of foods for health. Positive relationships were showed between intake of nutritional tablet and nutritional status, between less vegetable intake and less intake of calorie, fat, sugar and fiber and between appetite and vitamin B$_1$ and vitamin C. The result showed that the shorter period staying in hospital, the more intake of sugar, vitamin A and vitamin C.

This study aimed to investigate the effects of job satisfaction and self-esteem on psychological burnout in dietitians at a geriatric hospital in Busan. The survey was conducted from July 8 to August 31, 2014, and the data were analyzed using the SPSS program. The age group of over 36 years showed higher job satisfaction than the 'Under 25' group. Subjects that worked less than 2 years at their present jobs showed lower job satisfaction in job-itself than the 'Over 4 years' group did, and those who worked less than 1 year showed lower job satisfaction in terms of communication, appraisal compensation, and co-workers than did the other groups. Those who worked in '100~149 bed' hospitals showed higher job satisfaction than those in the 'Under 100 bed' group did. 'Over 200 bed' hospital dietitians showed higher satisfaction in supervision of superiors than did the other groups. Their experience of psychological burnout turned out to be 2.39 out of 5. Psychological burnout had a negative relationship with job satisfaction and self-esteem. Higher emotional exhaustion correlated with lower satisfaction in job-itself, less communication, and less supervision of superiors. Dehumanization correlated with lower satisfaction in job-itself, lower self-esteem, and worse communication, and while decreased personal achievement correlated with lower self-esteem, worse co-workers, lower satisfaction in job-itself, worse appraisal compensation, and worse communication. These results suggest that it would be effective for prevention and management of psychological burnout to mediate factors of job-itself, communication, supervision of superiors, co-worker, and appraisal compensation of dietitians in geriatric hospitals.

In this study, Hazen-Williams C value of pipes in wide waterworks system was estimated and statistically analyzed. Hazen-Williams C value of water pipe was predicted after 20 years of service period. From the results, it was found that C value of water pipe for treated water maintained higher value of 110 after 20 years of installation. Furthermore, it was found that velocity coefficients of steel pipe for less than and more than 20 years of installation were 117.7 and 109.3, respectively. C value of ductile iron pipe for less than and more than 20 years of installation were 118.1 and 114.2, respectively. In this study, it was also found that small value of C is used in the design of water pipe system. Therefore, excessively bigger size of pipe can be determined in the design of water pipe system. From the results of present study, optimum value of C can be used to avoid the oversized design of water pipe system.

Background: To investigate the association between regular physical exercise and falling experience for 2 years and fear of falling (FOF) in Korean middle-aged and elderly population. Methods: Data from the Korean Longitudinal Study on Aging was used and 3,871 participants who exercised regularly were included at 2006 and follow-up until 2018. An analysis was performed to investigate the association between exercise (exercise time per week and duration) and falls (experience over past 2 years and FOF) using the generalized estimating equation model. Results: Compared to those who exercised more than 5 hours a week (reference group), those who exercised less than 3 hours were more likely to experience falls and FOF (odds ratio [OR], 1.334; 95% confidence interval [CI], 1.059-1.682; OR, 1.218; 95% CI, 1.119-1.326, respectively). Compared to the group who exercised for more than 5 years, those who exercised for less than 1 year were more likely to experience FOF (OR, 1.310; 95% CI, 1.162-1.478). Conclusion: This study showed that there was a negative relationship between physical exercise time and falling experience and FOF in Korean 45 years or more community-dwelling adults. Based on these results, physical activity can be expected to have a positive effect on fall prevention, which implies the need for policy and research on long-term physical activity programs.

Background: The aim of this study was to provide insight on dental fear amongst schoolchildren and evaluate the association between caries experience and fear of dental procedures. Methods: A sample size of 250 students (both sexes) of ages 10-14 years were enrolled in the study. Before dental examination, each participant was informed about the study and given the Children's Fear Survey Schedule - Dental Subscale (CFSS-DS) questionnaire. Children who scored greater than 38 were included in the 'with dental fear' group and those who scored less than 38 were assigned to the 'without dental fear' group. All oral check-ups were carried out on the school premises according to WHO criteria. Results: There were 105 children (42%) who experienced dental fear. As CFSS-DS scores increased, scores on the Decayed, Missing and Filled Surfaces Index (DMFS) also increased. Scores were highest on "injections" followed by "dentist drill" and "feeling of choking". Children were significantly less anxious about items of dental treatment if they had experienced that particular form of treatment. Female participants were found to be more dentally anxious than the male participants. Conclusions: The data revealed dental fear in 10-14 years old children and showed that dental fear scores decreased with increase in age and experience.
