A CCTV inspection method has been widely used to assess sewer condition and performance, but Korea lacks a proper decision support system for prioritizing sewer repair and rehabilitation (R&R). The objective of this paper is to introduce the results that we have developed in the Sewer Condition Assessment and Rehabilitation Decision-making (SCARD) Program using MS-EXCEL. The SCARD-Program is based on a standardized defect score for sewer structural and hydraulic assessment. Priorities are ranked based on risk scores, which are calculated by multiplying the sewer severity scores by the environmental impacts. This program is composed of three parts, which are decision-making for sewer condition and performance assessment, decision-making for sewer R&R priority assessment, and decision-making for optimal budget allocation. The SCARD-Program is useful for decision-makers, as it enables them to assess the sewer condition and to prioritize sewer R&R within the limited annual budget. In the future, this program logic will applied to the GIS-based sewer asset management system in local governments.

Pulse wave velocity (PWV) is used to non-invasively estimate the severity of arteriosclerosis by measuring the patient's arterial stiffness comparing with each normal reference range according to their ages. Increased arterial stiffness is closely related to both atherosclerosis and arteriosclerosis, which have been known for causes of cardiovascular disease and stroke, also negatively affects the prognosis and the re-occurrence in patients with stroke. The study is focused on how brachial-ankle pulse wave velocity (baPWV) is related to cardiovascular disease risk factors in patients with acute stroke. There were 114 subjects, 69 males and 45 females, all in their 60's and had PWV test for acute stroke. The results are as follows: the group with increased arterial stiffness showed significant increase in HbAlc, total cholesterol, RSBP (resting systolic blood pressure), CSBP (central systolic blood pressure) and CDBP (central diastolic blood pressure). Cross tabulation test showed that there was a significant relationship only between the group with increased arterial stiffness and diabetes mellitus (DM). Therefore, it might be useful for preventing re-occurrence and making a favorable prognosis to promptly adjust DM and hypertension-related risk factors in patients with acute stroke.

Purpose: This study was to investigate the prevalence of depressive symptoms and risk factors in elderly people (old vs oldest-old) with arthritis. Methods: The Korean Longitudinal Study of Aging (KLoSA) was used with a sample of 1,084 elderly people with arthritis aged 65 or above. Results: We found that the prevalence of depressive symptom was greater for oldest-old people (66.7%) compared to old people (56%). Significant differences between old people and oldest-old people were found for education, living with spouse, number of generation, regular exercise, body mass index (BMI), ADL limitation, self-rated health, and depression. Significant differences existed between depression and non-depression in terms of all variables except region and BMI among old people. But, among the oldest people, ADL limitation and self-rated health showed differences. The Logistic regression analysis revealed that religion, medical comorbidity, ADL limitation, self-rated health were significantly associated with depressive symptoms in old people. But, in oldest-old people, none of the variables were associated with depressive symptoms. Conclusion: The findings show that there are age differences in depression and related factors in elderly people with arthritis. Longitudinal studies, which covered depressive symptom severity and which are controlled for a large number of potential confounders, will need to complement the results of this study in the future.

Cumulative trauma disorders(CTDs) of the upper extremities among the workers at manufacturing workplace have become a serious problem in Korea. However, most of the studies on the CTDs carried out in this country have focused on the Video Display Terminal(VDT) operators. In fact, high rates of the CTDs have been reported for telecommunication employees, and the CTDs associated with VDT use in telecommunication industries pose great health and social problems in Korea today. On the other hand, there are few studies on the CTDs among the manufacturing workers, and the severity of the problem was much under-reported. This study reports and discusses the results of the literature review on the cross-sectional studies of the CTDs, along with the analysis of the problems associated with identification, medical examinations, and ergonomic evaluation of the disorders. Also a checklist was developed for the use of quick screening tool for risk factor analysis. Consistency of the checklist was validated with the field studies of several manufacturing workplace. Current issues and suggestions for future ergonomic studies are also addressed.

Formal Safety Assessment (FSA) has been mostly implemented on the hardware aspects of vessels. Although there are guidelines regarding human error FSAs, there have not been many assessments in such areas. To this end, this study seeks to use precedent studies for the safe operation of DP vessels, conducting an FSA regarding human error of DP LOP (Loss of Position) incidents. For this, the study referred to precedent studies for the frequency of DP LOP incidents caused by human errors, adding the severity of LOP incidents, and then applying them to the Bayesian network. As a result, the study was able to confirm that among DP LOP incidents caused by human errors, the drive-off from skill-based errors was 74.3% and the drive-off from unsafe supervision was 50.5%. Based on such results, RCOs (Risk Control Options) were devised through a brainstorming session with experts coming up with proposals including providing mandatory DPO training, installing DP simulator on the vessels, drawing up measures to understanding the procedures for safe operation of DP vessels. Moreover, it was found that mandatory DPO training is reasonable in terms of cost benefits and that while installing a DP simulator is not suitable in terms of cost benefits, it can significantly reduce risks when operating DP vessels.

Purpose: Pain caused by osteoarthritis is primarily nociceptive pain; however, it is considered that a component of this pain is due to neuropathic pain (NP). We investigated the effects of total hip arthroplasty (THA) in patients with NP diagnosed by the PainDETECT questionnaire. Materials and Methods: One hundred sixty-three hips (161 patients) were evaluated. All patients were asked to complete the PainDETECT questionnaire based on their experience with NP, and clinical scores were evaluated using the Japanese Orthopaedic Association (JOA) Hip Score before and after THA. Results: The patients of 24.5% reported NP before THA; 5.5% reported NP 2 months after THA. Prior to THA, there was no significant correlation between the PainDETECT score and the radiographic severity; however, there was a significant correlation between the PainDETECT score and JOA score. NP at 2 months after THA was not significantly correlated with pain scores at 1 week after THA; however, a significant correlation was observed between the preoperative pain score and NP at 2 months after THA. Conclusion: THA was useful for relieving nociceptive pain and for relieving NP in patients with hip osteoarthritis. Preoperative pain was a risk factor for NP after THA. Controlling preoperative pain may be effective for reducing postoperative NP.

This study identified the severity of youth gambling behavior and analyzed the impact of stress, impulsivity, peer attachment and social interest on youth gambling behavior. Based on the results of the study, the government sought to help understand teenagers who are addicted to gambling and to help them maintain psychological and social stability and healthy living. A total of 237 high school students were surveyed. According to the analysis, the prevalence rate was found to be 3.4 percent of the problem gambling group and 9.3 percent of the medium-risk gambling group, and a total of 12.7 percent was addiction. Low-risk gambling groups accounted for 16.9 percent and non-problem gambling groups accounted for 70.5 percent. By gender, male students have more serious gambling problems than female students. As a result of dividing the group that experienced gambling more than once and the group that did not experience gambling into gambling group and non-gambling group, the two groups showed significant differences in impulsiveness, avoidant attachment, and interest in others. Furthermore, a correlation analysis was conducted to examine the relationship between these factors and the level of gambling behavior, showing that only impulsivity was significant.
