<P> The growth factors, such as temperature, humidity, CO2, EC and pH that affect the environment of a greenhouse. High-income crops such as paprika, strawberry, and tomatoes are sensitive to temperature and humidity during growth. In this study, a basic performance test of sensors and control interface was conducted to remotely control temperature and humidity. The remote monitoring and control system consists of a sensor interface, a control interface, and a communication module. First, the basic test of sensor interface was carried out to improve the data stability by keeping it in small plant factories. Secondly, the automatic control test of the heater and the dehumidifier depending on the set value of the sensor was carried out. The relative humidity was 80%, 85%, and 70% respectively. The monitoring performance was acceptable when the distance between the sensor and the ZigBee module was within 10m. Although data transmission rate was affected by the presince of obstacles, sensor data reception rate was more than 98%. The automatic control experiments were conducted and analyzed by measuring the automatic control time to temperature and humidity in each environment in a small plant factory. In order to improve the performance and to apply in the larger greenhouse, additional tests are required in various environment and crop cultivation conditions; the control algorithm should be inproved as well. </P>

<P> Whiteflies are small insect which typically eats on the underside of plant leaves. Nowadays damage caused by whitefly is consistently increased. The majority of farmers use pesticide to eradicate harmful insects; however, pesticide causes a severe environmental pollution. Therefore, an environment-friendly control technology for pesticide is necessary to be developed. In the study, an automated remote control system was designed and fabricated to eradicate whitefly. The system was consists of a rail-moving motor, a fan-blower, an electric wire mesh, and UV lamps. Every componets in the system was individually controlled. The moving speed and blowing speed of the unmanned collecting device was controlled using the pulse width modulation (PWM) of the motor drive and the stepper motor. Experiment results showed that the driving speed of the driving motor and the blowing fan motor can be controlled by the voltage. In conclusion, the environment-friendly unmanned collector could control the whitefly by combining the driving speed and the blowing speed within the desirable range. </P>

A Study on the Rotating Ring Using Air Bearing in Yarn Manufacturing Process

장승호 한국생산제조학회 2010 한국생산제조학회지 Vol.19 No.5

The increase of the spindle speed to enhance the productivity in ring spinning processes has been limited by yarn tension and heat generation of the traveller/ring. The main causes of yarn tension are 1) the force added directly to the yarn by the rotation of the spindle and 2) the centrifugal force exerted by the yarn balloon generated by traveller rotation. The dominant causes of heat generation are 1) the friction between the ring and traveller and 2) the friction between the traveller and yarn. These factors cause yarn end-breaks and heat damage. In the case of the staple yarn manufacturing process for PET (polyester) and nylon (a heat plasticity material), the rotational speed of the ring spinning system has deteriorated to 10,000rpm. The objective of this study was to develop a rotating ring which has dynamic stability, high productivity and a simple structure to overcome the limitations of the conventional fixed ring/traveller system. The results of this study revealed that the spinning tension could be reduced by 67.8% using the newly developed rotating ring.

Objectives:Outpatient treatment orders refer to a mandatory social program in which mentally ill persons are ordered by the court to participate in specified outpatient treatment programs. This study aimed to investigate the factors that affect outpatient treatment orders and adherence to outpatient treatment in mental health patients. Methods:A survey on outpatient treatment orders and adherence to outpatient treatment was conducted on 60 psychiatrists between October and November 2016. The questionnaire items were drafted based on a literature review, and they were then evaluated by 3 psychiatrists and 1 law school professor before being finalized. Answers from the respondents were analyzed using descriptive statistics, and the median, maximum, and minimum values of the effectiveness scores of outpatient treatment orders were calculated. Results:Among the 60 psychiatrists, 45(75.0%) were aware of outpatient treatment orders; however, only 2 out of the 45(4.0%) had actually used the program in the last 12 months. The subjective effectiveness was very low, with only 40 points out of 100. Furthermore, of the readmitted patients, 37.7% had received continued outpatient treatment, whereas 53.1% chose to quit the outpatient treatment programs, meaning that the number of dropouts was higher. Among the discharged patients, approximately two-thirds were receiving continued treatment. With regard to follow-up for dropouts, majority of the responses were either “Not taking any action”(n=27) or “Not following up”(n=15). Only two respondents answered “Contact the community mental health promotion center,” meaning that this response was very rare. Meanwhile, when asked about efficient measures to be implemented for dropouts, a vast majority of the respondents(n=30) selected the answer “Work with the community mental health promotion center.” Conclusions:The outpatient treatment orders currently being administered were found to be ineffective, and the associated adherence to outpatient treatment was also found to be extremely poor. Hence, the effectiveness of the therapeutic interventions could benefit from institutional as well as administrative improvements. Community mental health promotion centers are expected to have an important role in the future. 연구목적외래치료명령제는 정신질환을 앓고 있는 사람이 특정한 외래치료 프로그램에 참여하도록 법에 의해 명령을내리는 사회적 강제 제도이다. 본 연구에서는 외래치료명령제 및 정신질환자들의 치료 순응도에 영향을 미치는 요인들에 관해 알아보고자 하였다방 법정신건강의학과 전문의 60명을 대상으로 2016년 10월에서 11월까지 외래치료명령제 및 치료 순응도에 관한설문조사를 실시하였다. 설문지 각 문항은 문헌조사를 통하여 초안을 작성하고 3명의 정신건강의학과 전문의및 1명의 법학전문대학원 교수의 의견 조회 과정을 거쳐서 최종적으로 확정하였다. 설문에 응답한 대상자들의답변을 기술 통계를 이용하여 분석하였으며, 외래치료명령제의 실효성 점수에 대해서는 중앙값과 최고치, 최저치를 알아보았다. 결 과60명의 정신건강의학과 전문의 중에서 45명(75.0%)이 외래치료명령제를 알고 있었지만, 지난 12개월 중에이를 이용한 전문의는 2명(4.0%)이었고, 주관적 실효성 점수는 40점/100점으로 그 실효성은 매우 낮게 나타났다. 또한 재입원 환자 중 외래 치료를 지속적으로 받았던 환자의 비율은 37.7%, 외래치료를 임의 중단한 환자비율은 53.1%로 임의 중단 환자가 차지하는 비율이 더 높았다. 퇴원 환자 중에서는 약 2/3가량이 지속적인 치료를 받고 있었다. 임의로 치료를 중단한 환자의 관리방법으로 ‘아무런 조치를 취하지 않는다’(n=27)와 ‘파악하지 않음’(n=15)가 대부분이었지만 ‘정신건강증진센터 연락한다’는 의견은 2명으로 매우 저조하였다. 또한 임의중단 환자에 대한 효율적인 조치로서는 ‘정신건강증진센터에 연계해야한다’는 의견이 가장 많았다(n=30). 결 론현재 시행되는 외래치료명령제는 실효성이 낮고, 외래치료 환자의 치료순응도 또한 매우 저조하였다. 따라서 이에 대한 효과적인 개입을 위해 제도적, 행정적 개선이 필요하며, 향후 정신건강증진센터의 역할이 중요할것으로 판단된다.

Literature Review of the Usefulness of Smartphone for the Evaluation and Treatment of Mental Disorders

장승호,우영섭,이상열,박원명 대한우울조울병학회 2020 우울조울병 Vol.18 No.1

The drastic increase in mental illnesses is a global problem. Prompt improvement of symptoms through early intervention, analysis of drug efficacy, and evaluation of treatment compliance are key strategies to address this issue. However, the traditional diagnostic and therapeutic methods for mental illnesses entail assessments based on interviews or questionnaires, which require a lot of time and money. The widespread use of smartphones and their applications in recent years has made it easier to assess mental illnesses and access to treatment. However, the reliability and validity of use of smartphone applications as an assessment tool for mental illnesses has been questioned since these applications are largely based on the existing questionnaire assessment methods. To overcome these problems, use of biosensor-based smartphone applications for the diagnosis and assessment of mental illnesses is being studied. This study will introduce the current status of this approach and discuss the future prospects.

소방관에서 기능성 소화불량에 대한 심리사회적 요인의 영향 및 삶의 질에 관한 연구

장승호,류한승,최석채,이혜진,이상열,Jang, Seung-Ho,Ryu, Han-Seung,Choi, Suck-Chei,Lee, Hye-Jin,Lee, Sang-Yeol 한국정신신체의학회 2016 정신신체의학 Vol.24 No.1

연구목적 소방관에서 기능성 소화불량의 유병률이 높고 기능성 소화불량의 발현과 악화에 심리사회적 요인이 깊이 연관되어 있음에도 불구하고 이에 관한 연구는 매우 부족한 상황이다. 따라서 본 연구에서는 소방관들을 대상으로 기능성 소화불량에 관련되는 심리사회적 요인의 특징을 알아보고 삶의 질에 미치는 영향을 파악하고자 하였다. 방 법 소방관 1,217명을 대상으로 로마 III 진단기준에 따라 기능성 소화불량 집단을 선별하였다. 인구학적 요인을 조사하였으며 심리사회적 요인을 평가하기 위해 Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder questionnaire-7(GAD-7), Korean Occupational Stress Scale(KOSS), Ways of Coping Checklist(WCCL), Rosenberg's Self-Esteem Scale(RSES) 그리고 World Health Organization Quality of Life Scale abbreviated version(WHOQOL-BREF)를 사용하였다. 기능성 소화불량에 따라 집단을 나누고 교차분석(chisquare test)과 독립표본 t-검정(independent t-test)을 사용하여 집단 간의 차이를 알아보았다. 또한 KOSS의 각 하위 영역별로 기능성 소화불량의 위험도를 평가하기 위해 로지스틱 회귀분석(logistic regres-sion analysis)을 시행하였다. 기능성 소화불량 집단의 삶의 질과 독립변인들의 상관관계를 파악하기 위해 Pearson 상관분석(Pearson's correlation test)을 시행하였으며, 위계적 회귀분석(hierarchical regression anal-ysis)을 통해 기능성 소화불량 집단의 삶의 질에 영향을 미치는 예측 요인을 알아보았다. 결 과 기능성 소화불량 집단은 남성(p=0.006)이 많았고, PHQ-9(p<0.001), GAD-7(p<0.001), KOSS(p<0.001) 점수가 유의미하게 높았으며, RSES(p=0.008), WHOQOL-BREF(p<0.001) 점수는 유의미하게 낮았다. KOSS 하위 영역 중 높은 직무요구도(OR 1.94, 95% CI : 1.29-2.93), 부적절한 보상(OR 2.47, 95% CI : 1.61-3.81), 그리고 불편한 직장 문화(OR 1.51, 95% CI : 1.01-2.24)에서 기능성 소화불량의 위험도가 높았다. 기능성 소화불량 집단의 삶의 질에 대한 최종 회귀모델에서 우울증상과 직무스트레스가 낮고, 자아존중감이 높은 것이 삶의 질의 42.0%를 설명했다. 결 론 본 연구 결과 기능성 소화불량 및 삶의 질에 대한 심리사회적 요인의 영향이 확인되었다. 따라서 향후 기능성 소화불량의 평가에 있어 내과적 접근 뿐만 아니라 정신건강의학과적인 접근이 동시에 이루어져야 할 것으로 판단된다. Objectives : The purpose of this study was to investigate the characteristics of psychosocial factors related to functional dyspepsia(FD) and their effects on quality of life(QOL) in firefighters. Methods : This study examined data collected from 1,217 firefighters. We measured psychological symptoms by Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder questionnaire(GAD-7), Korean Occupational Stress Scale(KOSS), Ways of Coping checklist(WCCL), Rosenberg's Self-Esteem Scale(RSES) and World Health Organization Quality of Life Scale abbreviated version(WHOQOL-BREF). Chi-square test, independent t-test, Pearson's correlation test, logistic regression analysis, and hierarchical regression analysis were used as statistical analysis methods. Results : For the group with FD, the male participants showed significantly higher frequency(p=0.006) compared to the female participants. The group with FD had higher scores for depressive symptoms(p<.001), anxiety (p<.001), and occupational stress(p<.001), and did lower scores for self-esteem(p=.008), quality of life(p<.001) than those without FD. The FD risk was higher in the following KOSS subcategories: job demand(OR 1.94, 95% CI : 1.29-2.93), lack of reward(OR 2.47, 95% CI : 1.61-3.81), and occupational climate(OR 1.51, 95% CI : 1.01-2.24). In the hierarchical regression analysis, QOL was best predicted by depressive symptoms, self-esteem, and occupational stress. Three predictive variables above accounts for 42.0% variance explained of total variance. Conclusions : The psychosocial factors showed significant effects on FD, and predictive variables for QOL were identified based on regression analysis. The results suggest that the psychiatric approach should be accompanied with medical approach in future FD assessment.

기저세포암의 증식 및 성장에 대한 면역 화학 염색 연구

장승호 충북대학교 의과대학 충북대학교 의학연구소 1994 忠北醫大學術誌 Vol.4 No.2

기저세포암은 피부과 영역에서 가장 많은 악성 종양으로 비교적 조직 생검이 쉽고 유병율이 높기때문에 피부 종양 연구에 좋은 대상이다. 특히 종양 억제 유전자와 세포 증식 관계의 관찰 및 기저세포암 성장에 있어서 여러 성장인자들의 관찰은 발암과정 연구에 도움이 되리라 사료된다. 기저세포암 13예를 대상으로 면역 조직 화학 염색을 시행하여 다음과 같은 결론을 얻었다. 1. 기저세포암 13예중 12예에서 TGF-α의 양성 반응을 보였으며 그중 7예에선 미만성 염색을 5예에선 국소적 염색의 결과를 얻었으며 5예에선 종괴 주위 기질에서도 양성소견을 보였다. 2. 기저세포암 13예중 10예에서 EGF Receptor에 양성 반응을 보였으며 그중 6예에선 미만성 염색을 4예에선 국소적 염색의 결과를 얻었다. 3. 기저세포암의 P53염색상 8예에서 양성 반응을 보였다. 4. 기저세포암의 PCNA염색상 표지 지수는 20.5 ±2.8로서 대조군 2.5 ±1.0보다 의미있게 증가되어 있었으며 증식되는 세포는 종양 가장자리에 주로 분포됨을 알 수 있었다. 우리는 위의 실험 결과로 기저세포암 생성에 있어 성장인자의 autocrine작용 및 종양주위 기질의 종양성장에 미치는 영향을 유추할 수 있었다. 또한 종괴내에서 증식 세포의 분포 양상관찰 및 p53 단백의 발현 증가가 꼭 증식하는 세포의 반영이 될 수 없음을 알 수 있었다. Basal cell carcinoma is the most common malignancy in human skin. Our purpose was to investigate the pattern of growth factor expression and proliferative activity in basal cell carcinoma, using antibodies against TGF-α, EGF receptor, p53 protein and PCNA. Results are followings. 1. 12 of 13 basal cell carcinoma showed positive staining with TGF-α antibody including 5 cases of focal staining and positive stainings of tumor stroma were showed in 5 cases. 2. 10 of 13 basal cell carcinoma showed positive staining with anti EGF receptor antibody including 4 cases of focal staining. 3. p53 immunoreactivity was observed in 8 cases of 13 basal cell carcinoma. 4. The labelling index of basal cell carcinomas was significantly higher(20.5 ±2.8) than that of the normal skin(2.5 ±1.0). And proliferating cells were concentrated in periphery of tumor masses. We concluded that growth factors such as TGF-α, EGF receptor appear to involved in basal cell carcinoma development but their role are not yet clear. and p53 overexpression is not simply a reflection of increased cellular proliferation.
