건성안은 다양한 환경노출로 인해 생길 수 있다. 본 연구에서는 눈에 자극감을 줄 수 있는 자외선 차단제와 건성안의 연관성에 대해 조사하고자 하였다. 총 30명(남28명, 여2명)을 대상으로 하여 비침입성 눈물막 파괴시간 검사(NIBUT)와 맥모니 설문, 자각설문을 실시하였다. 자외선 차단제를 바른 후의 NIBUT값이 바르기 전보다 감소하는 것을 알 수 있었고, NIBUT값의 차이가 심했던 C제품이 자각 설문에서도 가장 불편했다고 답변하였다. 자각 설문에서 자극이 있다고 답한 대상자는 15명(50%), 자극이 없다고 답한 대상자는 15명(50%) 이였으며, 자극이 있는 집단의 맥모니 설문 점수가 높게 나왔다. 건성의안 기준에서도 위와 같은 결과이었으며, 모두 경계성 유의성을 나타냈다(p=0.049, p=0.051). 본 연구를 통해 자외선 차단제가 눈에 영향을 줄 수 있고, 건성안에 연관이 있다는 것을 알 수 있었다. 디지털 환경 요인들로 인해서도 눈에 자극증상과 변화를 줄 수 있으므로 환경유해물질 및 디지털 환경이 눈건강에 미치는 영향을 파악하는 융합 연구가 필요할 것이다.

Purpose: The purposes of this study were to survey the extent of pain and discomfort in the musculoskeletal system among visiting housekeepers, above all concerning neck, shoulder, back, wrist, knee, and arm pain and to find possible relations between symptoms and various working conditions. Method: A questionnaire was answered by 174 woman visiting housekeepers living in Kyeonggi-do and Seoul from December 1, 2003 to February 30, 2004. The symptoms of musculoskeletal system were coded by the pain index which illustrates the extent of the symptoms, and analyzed in view of NIOSH guideline and Kim, et. al.'s notion. Result: 1. As to the complaint rate of subjective musculoskeletal symptoms by body region, the figure was the highest for shoulder with 78.2%, followed by back with 66.7%, knee 53.6%, neck 56.3%, wrist 40.2%, and arm 29.2%, respectively. The logistic analysis showed shoulder pain and arm pain have no relation with working and health conditions, and back pain was significantly related to current health condition. In same way, knee pain and wrist pain were found to be mainly related to marital status. 2. Following the NIOSH guideline, the positive rate of subjective musculoskeletal symptoms was found out in following order: shoulder 69.5%, back 59.2%, knee 54%, neck 46%, wrist 32.8%, and arm 25.3%. To investigate the main cause of each disease, the symptoms were classified by pain index, where the value of more than 3 comes to the NIOSH case, and analyzed in term of complaint rate using discrete logistical method : shoulder pain was highly related to the housekeeping time after work, back pain was to current health condition and the heavy weight carrying and neck, wrist, arm pain were commonly related to the ordinary health condition. For knee pain, working speed was a main cause. 3. In view of Kim et. al.'s standard, where the pain index is over 7, the positive rate was showed in order slightly different from previous analyses : shoulder 33.3%. knee 29.9%, back 28.2%, neck 17.2%, wrist 17.2%, and 16.7%. From the logistical analysis, insufficient rest was shown as the main cause of shoulder, back, arm and wrist pain. For neck pain, ordinary health condition was mainly related. In case of knee pain, any apparent relation is not found. Conclusion: According to the logistic regression analysis of musculoskeletal system, there was strong suggestion that the less insufficient physical rest, the more significant disorder complaint. This means that the most musculoskeletal symptom among the visiting housekeepers can be prevented and cured by sufficient physical resting.

In the case of system like MES, various sensors collect the data in real time and save it as a big data to monitor the process. However, if there is big data mining in distributed computing system, whole processing process can be improved. In this paper, system to analyze the cause of operation deviation was built using the big data which has been collected from deasphalting process at the two different plants. By applying multivariate statistical analysis to the big data which has been collected through MES(Manufacturing Execution System), main cause of operation deviation was analyzed. We present the example of analyzing the operation deviation of deasphalting process using the big data which collected from MES by using multivariate statistics analysis method. As a result of regression analysis of the forward stepwise method, regression equation has been found which can explain 52% increase of performance compare to existing model. Through this suggested method, the existing petrochemical process can be replaced which is manual analysis method and has the risk of being subjective according to the tester. The new method can provide the objective analysis method based on numbers and statistic.

Pain, which is the most significant issue for the physical therapist, is the cause of various diseases until it disappears, and results in a lot of obstructions to treatment. Pain is very complicated. It is a subjective symptom that informs of a pathologic condition in the body, and one of the unpleasant experiences that people have. It is accompanied with anxiety and fear. Many researchers including Krause(1987) have identified the pain mechanism based on pain perception for many centuries and they have suggested many theories as they believed that pain management was possible. Reviewing the contents of psychoanalysis, uncontrollable pain that can't be explained is described as a defense mechanism to an unconscious psychological conflict. That is, mental pain is transferred to the body and the pain becomes unbearable. What is important is, like Keefe(1992) said, that the pain experience itself is primary stress and one should cope with it, whatever the cause of the pain. This paper investigates the background of the psychological theory of pain. Based on the efforts of previous studies, the next research generation will understand the treatment process for pain more dearly and will contribute to the prevention and protection from pain that humans undergo.

Backgrounds : sudden sensorineural hearing loss is defined as a disease that has abrupt onset of sensorineural hearing loss without definite cause. In some cases, this disease cause tinnitus, vertigo, headache addition to hearing loss. In traditional oriental medicine, sudden sensorineural hearing loss is could be diagnosed as deficiency of Yang-Gi(陽氣). Objects & Methods : This study is clinical observation about three sudden sensorineural hearing loss cases. For diagnosing in these cases, pure tone audiometry was used. For treatment, acupuncture, herbal-medicine and moxibustion therapy were used. Results & Conclusions : as follows. 1. Generally, in this disease, the shorter the whole period from the time that occurs to the time that starts to treat is, the more the results are better. The research shows that short-term case is more efficient than the other long-term two cases in the aspects of symptoms and pure tone audiometry . 2. In making a diagnosis of sudden sensorineural hearing loss and measuring the effect, subjective symptoms generally correspond to the improvement of pure tone audiometry, but not completely. Therefore, in treating patients, the doctor must consider these both aspects and keep the balance.

This research is intended to develop oral health education program that can improve quality of oral health of infants by investigating the actual condition of oral health education provided to students major in early childhood education and contents and method of oral health education that they needed. A questionnaire survey was conducted for 427 students enrolled in related departments such as the Early Childhood Education Division and the Early Childhood Education Department at five universities in Gyeongsangnam-do. Questionnaires consisted of general characteristics, awareness of oral health, presence of experience in oral health education, necessity of oral health education, preference for oral health education method, oral health education contents. The collected data were analyzed by SPSS(Statistical Package for the Social Science) Ver 20.0. 1. Presence of experience in oral health education based on the general characteristics showed statistically significant differences only concerning the 'school system' and the 'school year' (p<0.05), and subjective awareness of oral health based on the presence of oral health education experiences showed statistically significant differences concerning the 'interest in oral health' and the 'importance of oral health' (p<0.05). 2. Necessity of oral health education based on the subjective awareness of oral health showed statistically significant differences concerning the 'interest in oral health' and the 'importance of oral health' (p<0.05). 3. Necessity of oral health education based on the preference for oral health education method showed statistically significant differences concerning the 'intention to participate in oral health education' and the 'oral health education cycle' (p<0.05). 4. The most necessary information for oral health education is proper toothbrushing method 4.24, cause of tooth decay and prevention method 4.13, helpful food and poor food for tooth 3.97, toothbrush selection and storage method 3.85. Fluoride application and fissure sealant were lowest 3.38. As a result of this research, necessity of oral health education was large regardless of general characteristics, experience in oral health education, subjective awareness of oral health, and preference for oral health education. Also the more the 'interest in oral health' in 'subjective awareness of oral health', the more the 'necessity of oral health education' and 'intention to participate in oral health education'. Therefore it is necessary to develop systematic and repetitive oral health education for students major in early childhood education.
