In the industrial field, various type of fuel have been used for product processing facilities. Recent for 10 years, the usage of natural gas (NG) was gradually increased. Because it has many merits; clean fuel, no transportation, storage facility and so on. There are common safety concept that strict explosion protection approaches are needed for facilities where explosive materials such as flammable liquid, vapor and gases exist. But some has an optimistic point of view that the lighter than air gases such as NG disperse rapidly, hence do not form explosion environment upon release into the atmosphere, many parts has a conventional safety point of view that those gases are also inflammable gases, hence can form explosion environment although the extent is limited and present. In this paper, the heating equipments (Hot Oil Heater) was reviewed and some risk management measures were proposed. These measures include hazardous area classification and explosion-proof provisions of electric apparatus, an early gas leak detection and isolation, ventilation system reliability, emergency response plan and training and so on. This study calculates Hazardous Area Classification using the hypothetical volume in the KS C IEC code.

Background and Objectives:The most common cause of olfactory dysfunction is chronic rhinosinusitis, and endoscopic sinus surgery has been reported to yield beneficial outcome for the olfactory function. The purpose of this study was to study the benefits of endoscopic sinus surgery and investigate the influence of prognostic variables on the olfactory function in chronic rhinosinusitis patients. Materials and Method:We enrolled 52 patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with olfactory dysfunction from July 2000 through April 2003 at Bundang CHA General Hospital, College of Medicine, Pochon CHA University. Patients were classified into 3 groups (well-healing, persistent olfactory disturbance and worse groups). We statistically compared various prognostic variables, such as CT scores, age, gender, allergy, duration of disease. and previous nasal surgery history among the 3 groups. KVSS test was used (Korean Version of Sniffin’ Sticks test) for the evaluation of olfactory function. Results:Of the prognostic variables examined, CT scores, gender, allergy, and duration of disease had no influence on the prognosis of olfactory improvement. However, old age and previous nasal surgery were found to have statistically significance on the worse prognosis. The olfactory function improved in 88% of the patients following the endoscopic sinus surgery. Conclusion:We concluded that olfactory function of many patients with conductive disorder improved after endoscopic sinus surgery. Gender, allergy, duration of disease had no singnificant influence on the prognosis of olfaction. The severity of sinusitis and the extent of polyps were not consistent with the degree of olfactory repairment.

본 연구에서는 재활병원에 입원해 있는 기혼 뇌졸중 환자들의 성 생활 및 성 생활 만족도에 대해 조사하고, 성 재활 교육의 필요성에 대해 알아보고자 한다. 연구를 위한 이론적 고찰에서는 성재활의 선행연구들을 비교하여 보았으며 문화적 환경 및 사회 구조적 차원에 있어 장애인에게서 차별화 될 수 있었던 성 생활 및 성 생활 만족도를 알아보고 이로 인한 결과로 성재활 교육의 중요성을 제시하였다. 연구결과 환자들은 첫째, 성 생활에 관심을 많이 가지고 있지만, 실제로 참여하는 비율이 낮았으며, 만족도 또한 낮게 나타났다. 둘째, 환자들이 기본적인 일상생활활동의 일부인 성 생활에 참여하고 만족감을 느끼게 하는 것은 그들의 삶의 질을 향상시키는 데 도움이 될 것이라 생각된다. 셋째, 앞으로 작업치료 중재의 일부로써 이러한 성 재활에 대한 접근이 활발히 이루어질 수 있도록 많은 연구가 계속되어 질 것을 제안한다. Sexual Activity is basic desires and affect the quality of life. Individuals with disability have also sexual desires and may need other way to satisfying these desires. Thus, the purpose of this study were to research sexual activities, satisfaction of sexual activities, and necessity of sexual rehabilitation education for the married stroke patients in rehabilitation hospital. The subjects of this survey were the married stroke patients in the rehabilitation hospitals in Busan and Kyungnam. And they had enough cognition level to answer the questionnaire. Finally we had gathered 73 questionnaire and analyzed the results through frequency and percentage. As a result of this study, 28.8%(21 people) of 73 respondents said that they‘have sex’. Among those who have said‘have sex’, 71.5%(15 people) people have not satisfied their sexual relationship with their partner. In a question of feels and comfort of the sex, 76.2% (16 people) people answered‘generally not comfort'. The rest of 71.2%(52 people), who said‘have not sex', responded the reason for denial of sexuality are‘fear of recurrence’, ‘rejection of a spouse’,‘fear of failure’,‘impotence’, and‘loss of self-respect’. 61.6%(45 people) of total 73 patients have interest in sex. In comparison, 50.7%(37 patients) responded that they don’t try to get information about sexual rehabilitation. 54.8%(40 patients) responded that they generally need sexual rehabilitation education and 38.4%(28 patients) of them responded that they need the counseling for sexual rehabilitation when they ‘start the rehabilitation’. As the result of this research, most of the stroke patients have large interested in sexual activities but the most patients have not sexual activities and not been satisfied. It will be helpful to increase the quality of life that individuals with disability participate in the sexual activities as a part of basic activities of daily living and satisfy it. So we propose that sexual rehabilitation education as a part of occupational therapy should be achieved by occupational therapist and the more studies about sexual rehabilitation should be continued.

The present study attempted to investigate the angle of cervical vertebrae motions of thirty subjects who are seated in front of computers for a long time. The subjects were divided into Group A, B and C, which were for ultrasound treatment and relaxing exercise, for ultrasound treatment and massage, and relaxing exercise and massage respectively. This study made comparisons between groups of different ages and genders before treatment, between groups of different genders by segment before treatment, and between before and after treatment for each group. It also made multiple comparison based on the variance analysis among groups and comparison between Group A and B. From the results of this study, following conclusions were drawn. 1. When comparing the total means of different age groups, female subjects' angle of motions was wider than male subjects' in all age groups except the group at the age of 30-34. 2. When comparing the total means of different segments of cervical vertebrae, female subjects' angle of motions was wider than male subjects' in segment C3-4, C4-5 and C5-6. 3. Group A showed a significant difference from Group B and C in segment C4-5, and only Group C showed a significant difference in the other segments(p<0.05). 4. When comparing the total angle of cervical vertebrae motions between Group A and Group B, there was a slight but not significant difference in the angle(p<0.05).

The purpose of this study was to investigate the effect of task performance training on upper extremity and cognitive functions in stroke patients. The participants of the study included 24 stroke patients who were-hospitalized at a rehabilitation hospital in Busan, Gyeongsangnam-do. Upper extremity and cognitive functions were assessed using the BBT and PVFT and K-TMT-e B, respectively. The tests were performed for 30 minutes three times a week over a total of four weeks. The results of the single BBT, single phonological spelling test, and Korean Version of the Trail Making Test were significantly higher in the experimental group than in the control group. In addition, the results of the double BBT and dual phonological spelling test were higher in the experimental group than in the control group, and the experimental group was more effective than the control group in the Korean Version of the Trail Making Test. The results of the single BBT improved both in the experimental and control groups according to the treatment period. A dual task training program had a positive effect on upper extremity function and resulted in cognitive function improvement in stroke patients. From the findings of this study, we propose that dual task training should be implemented in clinical settings as occupational therapy during upper extremity rehabilitation for hemiplegia.

Purpose : This study aimed to investigate the effects of health science majors’ communication skills on their adjustment to college life. Methods : The subjects were 336 college students majoring in health science at colleges located in Busan. The survey’s questionnaire comprised 38 items, including 15 items for communication skills and 19 items for adjustment to college life. Results : In the gender-based comparison of communication skills and adjustment to college life, female students had better communication skills, with overall higher scores than male students for the understanding others and communication. In the age-based comparison of communication skills and adjustment to college life, students aged 21 to 22 showed the best communication skills, while students aged 18 to 20 exhibited the least communication skills. In terms of adjustment to college life, those aged 25 or older scored the highest, and those aged 21 to 22 scored the lowest. In the school-year-based comparison of communication skills and adjustment to college life, third- and first-year students showed the best and least communication skills, respectively. Overall, third- and fourth-year students were more adjusted at adjusting to college life than first- and second-year students. Third-year students also scored the highest in academic adjustment, whereas second-year students scored the lowest. In terms of relationships between the students’ communication skills and their adjustment to college life, communication skills were positively correlated with the following subdomains: understanding of others, self-expression, and communication. Communication skills also showed a positive correlation with adjustment to the college environment, including personal-emotional adjustment. Conclusions : The present study found that communication skills did not significantly affect health science majors’ adjustment to college life. However, given that communication skills are an essential factor for effective work performance and greater job satisfaction, it is recommended that colleges provide students with relevant education and experiences to help them enhance communication skills while in school.
