  • This study deals with the procedure of safety improvement, productivity increase, and tact-time reduction through setting up the system about preventive maintenance. Actually, it is hard to establish and carry out preventive maintenance, even though we recognize the importance of the system concerning time, cost, labor, and so forth. In this study in the viewpoint of cost we are for achieving maximum efficiency by change and reduction of planning process adapted to the special work group. At first we briefly will mention the kind, the necessity, and the concept of preventive maintenance, and then divide the equipment used in the assembly line into the two whether it is necessary or not by way of estimating the breakdown loss, comparing with general establishment of preventive maintenance and modifying it to the case. At the second step we will establish the operation system of plan management related to production and quality in the special case. Check period and category will be set by dividing the assembly equipment into LCL and Focus in the third step. The forth step will contain the operation procedure in detail. And then we must make check and repair record periodically. Finally, on the basis of the record the selection of checking of significance will be conducted. This results in safety improvement, tact time reduction, and productivity improvement.

  • Glaucoma is a potentially blinding chronic disease requiring life-long commitment to medical therapy. Failure to adhere to anti-glaucoma treatment may lead to disease progression and visual loss. This study surveyed the adherence to glaucoma eye drop and eye drop instillation technique of glaucoma patients and analyzed the improvement of the adherence and installation technique after patient education for eye drop instillation instructions. Collected responses were statistically analyzed using Kruskal-Wallis test, Mann-Whitney test, Chi-square test, Fisher's exact test, Spearman's correlation coefficient, or one sample proportion test. The survey after patient education for proper eye drop instillation revealed that, even if the patients experienced the adverse effect of their eyes getting dry, they used the eye drop more regularly. They were better at instillation techniques like putting the eye drop inside the eye, and also avoiding applying too much medication or touching their eye with the eye drop bottle. Also, when the patients were divided into groups based on etiologic division, there was difference among groups regarding which category they answered has improved. The result showed improvement in adherence to glaucoma eye drop and eye drop instillation technique after patient education, implicating that patient education is an important aspect of eye care for glaucoma patient and helps them participate in the proper management.

  • Purpose: The purpose of this study was to investigate the alopecia experience in adults and to explain the process of their experiences. Methods: Using a grounded theory methodology, 18 interviews were performed with fourteen men and four women, 34~57 years of age, suffering from alopecia. Data were analyzed using the constant comparative analysis method. Results: The core category emerged as "inescapable fetters". adults with alopecia engaged in three stages: embarrassment, seeking solution, and acceptance phase. Causal conditions were a vicious cycle of stress, biological factors and poor life style. Contextual conditions were recognition of irreversibleness, negative social awareness, and marriage. The central phenomenon of the adaptation process among the adults with alopecia was withdrawn life due to negative body image. Action/Interaction strategies included rely on medical treatment, efforts to take good care of hair, research for information treatment, efforts to cover up hair loss, and mind control. Intervening conditions were time cost, economic cost, support of surrounding people. Consequences was burden of unfinished lifetime homework. Conclusion: When caring for these adults, it is important to identify needs, allow patients to express what they want at that moment and support them in maintaining a daily life.

  • According to the results of a survey by Boeing, LOC-I (Loss of Control in Flight) was the highest in the number of deaths by fatality accident category in the past 10 years from 2012 to 2021, and the number of deaths worldwide due to LOC-I accidents was 757. It turned out to be the biggest cause of aircraft fatalities, with a figure close to twice the sum of UNK (Unknown or Undetermined), which is the 2nd place, and CFIT (Controlled Flight Into or Toward Terrain), which is the 3rd place. This study set six scenarios related to spatial disorientation that may occur during sensory-dependent flight targeting student pilots and instructor pilots at domestic designated specialized educational institutions using flight simulation training equipment, and in each scenario, the pilot's. The need for SDRT (Spatial Disorientation Recovery Training) is verified by analyzing the flight experience and recovery ability by qualification, and SDRT is repeatedly performed to verify and present the training cycle and time.

  • A stroke is a medical disease where a blood vessel in the brain ruptures, causes damage to the brain. If the flow of blood and different nutrients to the brain is intermittent, symptoms may occur. Stroke is other reason for loss of life and widespread disorder. The prevalence of stroke is high in growing countries, with ischemic stroke being the high usual category. Many of the forewarning signs of stroke can be recognized the seriousness of a stroke can be reduced. Most of the earlier stroke detections and prediction models uses image examination tools like CT (Computed Tomography) scan or MRI (Magnetic Resonance Imaging) which are costly and difficult to use for actual-time recognition. Machine learning (ML) is a part of artificial intelligence (AI) that makes software applications to gain the exact accuracy to predict the end results not having to be directly involved to get the work done. In recent times ML algorithms have gained lot of attention due to their accurate results in medical fields. Hence in this work, Stroke disease identification system by using Machine Learning algorithm is presented. The ML algorithm used in this work is Artificial Neural Network (ANN). The result analysis of presented ML algorithm is compared with different ML algorithms. The performance of the presented approach is compared to find the better algorithm for stroke identification.

  • Relatively young widows, who are left with young children by a sudden death of their husbands, will be faced with not only psychological troubles such as individual anxiety and frustration but also the dual burden of playing both father and mother roles in a family, Also, family members have difficulty in adapting themselves to new circumstances of the family system, the training and raising of family members, and management of the family economy. In this study, the realistic resources on the experience of middle-aged women who are bereaved of their husbands by accidents were explored. The purpose of this study is to help widows adapt to life in society and live a more positive life by setting a new goals and recovering from a lost and twisted life. 11 women, who have experienced the loss their husbands and live in the Seoul metropolitan area were studied. The research took 116 days from December 15, 1995 to April 8, 1996. The method of research was direct interviews. While having interviews with them, the contents were recorded with their consent. The ground theory was that used by Strauss & Corbin(1990) in the analysis of the data. 81 concepts were analyzed and they were subdirided into 22 subordinate categories through the course of the analysis. These were then classified into 9 general categories. In the course of being categorized, 'absurdity' was showed as a core category. The subordinate categories 'surprise', 'gloom', 'grudge', 'helplessness', 'emptiness', and 'loss' were united in the core category 'absurdity'. Ominous presentiment, belated notice, death, surprise, gloom, grudge, helplessness, emptiness, loss, the situation of the children, lack of support from neighbors, support from neighbors, mulling over ways to live, choosing a job, strengthening, reinforcement, burden, sadness, smoldering, yearning, overcoming these 22 subordinate categories were re-composed into 9 general ones the husband's death, absurdity, presence of children, existence of support, self-support ability, preparation of countermeasures, self-reinforcement, toilsomeness, and overcoming. 'Absurdity' widows experience was shown in the results of 'toilsomeness' and 'overcoming' through reaction, confrontation, and adaptation. According to the analysis the central phenomenon was absurdity, the causal condition of the death of a husband, the presence of children and the existence of support, and the meditated situation of self-support. To solve absurdity, the preparation of countermeasures and self-reinforcements were shown resulting in toilsomeness and overcoming. Through the contrast in the data, the following statements were deduced: (1) If the death of the husband is expected, the more a widow will feel absurdity. (2) The more children she has and the younger she is, the more a widow will feel absurdity. (3) The lower support she is given, the more a widow will feel absurdity. (4) The larger self-ability she has, the more actively she will prepare countermeasures. (5) The smaller self-ability she has, the more passively she will prepare countermeasures. (6) The larger self-ability she has, the weaker self-reinforcement she will preform. (7) The smaller self-ability she has, the stronger self-reinforcement she will perform. (8) The more actively she prepares countermeasures for absurdity, the better she will overcome. (9) The more passively she prepares counter measure for absurdity, the worse she will overcome. (10) The stronger self-reinforcement for absurdity she performs, the better she will overcome. (11) The weaker self-reinforcement for absurdity she performs, the worse she will overcome. Through the results in this study, the following suggested: 1) A study whose object is all family members, and a comparative study on the case of a husband who has lost his wife should be done. These studies can be expected to develop a more refined theory. 2) Because of the collapse of the extended family system and the changes of family culture in Korea, a widow's status and position are apt to be ambiguous between her husband's home and her parent's. Therefore a new study on family culture should be made. 3) A continuous study on growing social Self Help Groups should be requested for the widows of this study to re-establish and recover from their twisted and scattered lives.

  • Objectives: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. Methods: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain: severe gain), cigarette smoking (quitter; nor-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. Results: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0,001), but negatively with smoking (p=0,004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or hon-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). Conclusions: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

  • Crohn' disease is an auto-immune disease characterized by intermittent chronic diarrhea, high fever, weight loss, abdominal spastic pain or abdominal discomfort which is followed by granulomatous necrosis and cicatrical inflammation. It is also called segmental enteritis or granulomatous enteritis. In western medicine the exact cause is undefined, however it is presumed as an immunological unbalance in alimentary tract commoonly occured in ileum portion of small intestitine or ascending colon and therefore immuno suppressive agents(usually steroids) and anti-inflammatory drugs are prescribed. In case of emergency such as ileus, perforation of intestinal wall surgical methods are considered. In oriental medicine this falls under the category of diarrhea(泄瀉), dysentery(痢疾), splenic diarrhea(脾泄). As to the pathological mechanism the abnormal ascending and descending circulation of stomach and splenic energy(脾不升淸, 胃不下降) the hepatic stagnation(肝鬱氣滯) and dysfunction of small intestine in expelling urine and feces(小陽淸獨不利) all together causes such condition. Main treatments are inducing diuresis(利小便), warming kindey to reinforce yang(溫賢助陽), nourishing the middle energy to invigorate spleen(補中健脾), elimination of the dampness by cooling(淸熱燥濕). In this case the patient was diagnosed as soyangyin(少陽人) constitution and herb medicine soyangyin Hyongbangjihwan-tang(少陽人 荊防地黃湯), Sa-am acupuncture Sojangjeonggyeok(小腸政格) was applied. There was an significant improve in chief complaints and general conditions.
