그랩 크레인은 부두 항만으로 모래 및 토사가 퇴적이 되거나, 해저 공사를 하기 위해 다목적으로 사용된다. 그립 크레인의 구성 요소 중 와이어 드럼과 디스크 브레이크 패드는 핵심적인 소모품으로 많은 열이 발생되며 교체 시 가격이 매우 비싸다는 단점이 있다. 본 논문에서는 그랩 크레인의 와이어 드럼에 작용되는 디스크 브레이크 패드에 대한 열화상 진단 시스템을 제안한다. 제안된 시스템은 브레이크 고장 및 디스크 패드 손상 전에 디스크 및 패드 표면의 온도가 비정상적으로 분포하는 특징을 이용하여 열화상을 통해 패드 열 진단 분석을 수행한다. 따라서 기계 부품의 이상을 고장 전에 미리 발견하여 고장으로 인한 피해를 방지할 수 있으며, 과부하 유무를 상시체크하면서 크레인을 작동시켜 패드의 수명 연장과 비용을 절감할 수 있다.

탄성의치는 심미성, 유연성, 생체적합성 등의 장점이 있어서 최근 많이 사용되고 있다. 그러나 재료 자체의 유연성에 의한 의치의 운동 때문에 안정성에 대한 문제가 제기되고 있다. 저작 시 의치가 조직면으로 움직이면서 지지조직을 자극하게 되고, 이런 자극이 장기간 지속될 경우 외상과 잔존치조제의 급속한 흡수를 야기할 수 있기 때문이다. 본 증례에서는 안정, 유지 및 지지가 부족한 탄성의치를 장기간 사용하면서 지지점막의 지속적인 자극으로 인한 구개골 노출이 발생하였다. 안정성 및 유지력이 확보된 새로운 의치를 제작하여 환자의 불편감이 감소하였고 구개골 노출이 치유되었다. 탄성의치를 사용할 수 있는 증례를 신중하게 선택해야 하며 정기검진 및 적절한 처치를 시행하여 부작용을 예방할 수 있어야 한다.

Purpose: To analyze the differences of the Body Mass Index (BMI), blood biochemical indices (TC, TG, HDL, PP2) among college faculty members depending on their life styles and thereupon, provide for some basic data useful for healthcare education. Methods: 163 faculty members were sampled for a questionnaire survey and a medical checkup, both conducted from Jan. 20 to Jan. 26, 2010. Results: First, such blood biochemical indicesas BMI, TG, HDL and PP2 differed significantly depending on gender, while TC, TG and HDL differed significantly depending on age. Second, BMI differed significantly depending on drinking. Third, smokers showed significantly lower BMI and PP2 than non-smokers. Among the smokers, those smoking for 1-10 years showed a significantly lower level of TG. Fourth, those exercising as hard as sweating 3 times a week showed significantly lower BMI, TC and TG. Fifth, BMI was correlated positively with TC and TG, while being correlated negatively with HDL. On the other hand, TC was correlated positively with the TG which was correlated negatively with the HDL which was correlated positively with PP2. Conclusion: In order to prevent chronic diseases and live a healthy life, it must be necessary to control drinking, stop smoking and exercise regularly.

The relationship between body weight and body image, an objective and subjective measure of body shape, respectively, has long been a recurrent concern in the area of medical sociology and health-related studies. This concern stems from the argument and findings in the literature indicating that the two are not necessarily likely to be strongly correlated due mostly to the fact that one's own idea or conception about his/her body shape could be pretty different from one's actual shape. This study tries to empirically address the two issues based on the analysis of a national sample survey data in Korea: to what extent body weight and body image are correlated with or deviated from each other, on the one hand, and what factors help to account for the relationship between the two, on the other. The latest(2010) national sample data of KGSS(Korean General Social Survey) is used to evaluate the issues. Results of data analysis demonstrate that body weight and image have a moderate amount of correlation, and that the correlation tends to vary to a large extent depending on a few major socio-demographic and socio-economic characteristics. Most important, the risk factor analysis attempted in this study could identify several salient risk factors, which include gender, age, chronic diseases, smoking, physical exercises, and medical checkup. To be precise, those who may be best characterized as particularly risky to weight gains are females, who are in their 20's, who have chronic diseases, non-smokers, who exercise regularly, and who conduct medical checkups on a regular basis. To extrapolate, the findings suggest that the most typically risky kinds of individuals in Korea are "young women who care very much for their health." The findings are interpreted and discussed with suggesting a recommendation for further studies.

본 논문은 LEACH-Mobile를 사용하여 병원에서 환자들의 위치와 센서 데이터의 지속적인 수집을 시뮬레이션 하고자 한다. LEACH-Mobile(: Low Energy Adaptive Clustering Hierarchy)은 기존의 LEACH프로토콜에서 mobile노드를 추가하여 이동성을 향상시킨 프로토콜이다. LEACH-Mobile은 LEACH에서 이동성이 개선되었지만, 기존 LEACH보다 소모되는 에너지의 양이 더 많다. 여기서 LEACH-Mobile을 사용하는 이유는 병원의 모니터링시스템은 대체적으로 cctv나 간호사들의 주기적인 확인으로 이루어진다. 하지만 대부분의 병원은 환자수에 비해 간호사의 수가 적다. 그렇기에 간호사가 보지 못한 사이에, cctv의 사각에서 일어나는 사고에 환자가 다칠 가능성이 있다. 그래서 위치와 센서 데이터를 5개의 상황으로 지속적으로 수집하는 시뮬레이션을 하였고, 그 결과는 병원에서의 환자들의 동선 관리를 보다 효율적으로 하였다.

It is true that the dependency on import is currently high in case of the safety checkup system of domestic airplanes, and it is at the point of time that localization of HUMS for small airplanes is required. In this study, the design factors were selected for the lightweight of HUMS for small airplanes by using Pro-Engineer which is a design tool and Abaqus. 9 models were made through experiment plans with Taguchi method for this, and the each model for weight lightening was selected through vibration analysis and shock analysis while in operation with experiment profile values. After fabricating HUMS, it was verified that as a result of experiment with the same profile values as the analysis, there was similarity between the analyzed values and values of the experiment. As a result of performing weight lightening which is the purpose of the study, electronic performance for small airplanes is assured and a design plan reducing 15 % weight compared to the targeted weight was deduced. Besides, it could be verified that the light weight model satisfied the maximum allowable displacement value of PCB[printed circuit board] and accordingly satisfied electronic properties of HUMS. In this study, the reliability of a product was certified through the result of an experiment on ground. If the reliability of HUMS were verified through a test flight in the future, it is considered that it would make a big contribution to localization of aerospace electronic equipment.

Background: Acceptability of self-sampling HPV testing is confirmed worldwide. However, some cultural differences may affect this question. Therefore, this study was conducted to evaluate the acceptability of self-sampling HPV testing in Thai women. Materials and Methods: One hundred women aged 30-65 years with an intact cervix were included in this study. The participants were asked to do the Pap test by physicians and then brush type self-sampling instruments were assigned for self-collection and finally completed a questionnaire for acceptability evaluation. The questionnaire contains 2 parts. Part one covered general information of the participants and part two is the acceptability questions. Results: Mean age was 40.6 years. The incidence of high risk HPV detection in this study was 16%. The most common reason for doing Pap smear was for annual checkup. On the topic of ease of use, 85 % of the subjects agreed. Most of the participants (82%) reported that they felt less pain. However, reliability of the result was not satisfactory because 37% of the participants hesitated to rely on the results of the test. According to the price, if the price is less than 1,000 Baht (32.59 Baht = 1USD), 82% of the subjects would use it for their next screening. Conclusions: The acceptability of self-sampling device in this study is quite good but the reliability of the test was questioned by some of the participants. Moreover, the price of the test in Thailand may also influence the acceptability of the test.
