Objectives : We evaluated the risk of fracture associated with hypotension-related adverse drug reaction caused by taking alpha blockers to treat benign prostatic hyperplasia (BPH). Methods : We used the Health Insurance Review and Assessment Service database from January 1st 2005 to June 30th 2006 for this study. The male patients with BPH and who had a prescription for alpha blockers following any fractures were defined as the cases. We set the 20 day long hazard period prior to the index date and the four control periods whose lengths were same with hazard period. After 1:4 matching of the hazard and control periods, conditional logistic regression was used to calculate the odds ratios for the risk of fractures as related to the alpha blocker exposure. Results : Doxazosin and tamsulosin showed the increased risk of fractures, whereas terazosin did not. After stratification using the defined daily doses, a protective effect was shown for the patients who took terazosin at the doses lower than 0.4 DDD and the hazardous effect at the doses higher than or equal to 0.4 DDD. There was no significant difference for the risk of patients taking tamsulosin at the doses higher than 1.0 DDD but there was a statistically significant increase in the risk at the doses higher than or equal to 1.0 DDD. Conclusions : Alpha blockers for BPH may increase the risk of fracture in elderly patients who have comorbidities and take the concomitant medications. Alpha blockers need to be prescribed with caution, although some have high prostate specificity.

Although edible insects are attracting attention as future alternative food because of their nutritional, eco-friendly, and economic advantages and functionality, consumption is low, so measures to promote consumption are needed. The problems in edible insect consumption were identified as the aversion to the edible insects, lack of publicity for edible insects newly registered in the Food Code, and difficulties in continuously supplying high-quality edible insects and selling products. To solve these problems, it is necessary to establish effective public relations plans for new edible insects and develop processing methods for improving their taste and flavor, education content about edible insects, and products interesting to the target age. In addition, it is necessary to establish a one-stop cluster that can perform quality control of harmful substances and nutrients, purchase raw materials, sell products, educate, and publicize.

This study was conducted in order to examine the effects of horticultural therapy on stress in demented elders, and for this purpose, we analyzed stress-related physiological changes in demented elders under the care of an elderly facility who had not taken medication and consented to blood tests. The horticultural therapy program included only flower decoration, which was preferred by the participants, aiming ultimately to reduce stress. First, a one-to-one session was given for forming rapport and the horticultural therapist had many conversations about plants with the elders. Furthermore, the participants were induced to be absorbed into the horticultural activities, though a short while, so that they might forget troubles. Evaluation was made by measuring subjective stress and the blood cortisol hormone concentration before and after the horticultural therapy and examining differences between them. Subjective stress increased from 12.88 to 17.88 in the control group, but decreased significantly from 13.88 before the therapy to 6.38 after in the experimental group (p = 0.007). When the blood cortisol hormone level was measured as a physiological indicator of stress, it decreased significantly from $11.33{\mu}g{\cdot}L^{-1}$ before the horticultural therapy to $9.85{\mu}g{\cdot}L^{-1}$ after (p = 0.037). These results suggest that horticultural therapy reduces the blood cortisol hormone level and is effective in easing stress.

This study explores the use of virtual reality (VR) technology to identify and label key segments of the golf swing. To address the limitations of existing VR devices, we developed a platform to collect kinematic data from various VR devices using the OpenVR SDK (Software Development Kit) and SteamVR, and developed a semi-automated labeling technique to identify and label temporal changes in kinematic behavior through LSTM (Long Short-Term Memory)-based time series data analysis. The experiment consisted of 80 participants, 20 from each of the following age groups: teenage, young-adult, middle-aged, and elderly, collecting data from five swings each to build a total of 400 kinematic datasets. The proposed technique achieved consistently high accuracy (≥0.94) and F1 Score (≥0.95) across all age groups for the seven main phases of the golf swing. This work aims to lay the groundwork for segmenting exercise data and precisely assessing athletic performance on a segment-by-segment basis, thereby providing personalized feedback to individual users during future education and training.

As the long term care insurance for the elderly has been established for 3 years it was noticed that the success of the policy is depending on the care workers. This study is to analyze and evaluate what are the characteristics and factors influencing their job satisfaction. The questionnaire survey was conducted over 291 care workers who are employed at 61nursing home for the elderlyin Jeollanamdo. The survey result is as following. Firstly, 93.5% of workers were female, 78% of them were over 40-50 years old, and 68.7% of them werelower than a high school graduate as their academic background. Secondly, 63.2% were contract-based or temporary employees, 53.3% had a work-related education less than 5 times for the past year, and 79.7% had an annual salary lower than KRW 20 million. Thirdly, the overall job satisfaction was 3.19 on the Likert scale of 5. Also, the job satisfaction was higher for the care workers working and getting paid by home than by company, for full-time workers than temporary workers. In addition, it was found that the more workers have work-related education and the higher their annual salary is, the higher their job satisfaction is. The study evaluated the factor influencing on their job satisfaction and suggested the way to improve it based on the survey analysis.

Two major problems currently threaten human survival on Earth: climate change and the rapid aging of the population in developed countries. Climate change is a result of the increase in greenhouse gas (GHG) concentrations in the atmosphere due to the increase in the use of fossil fuels owing to economic and transportation development. The rapid increase in the age of the population is a result of the rise in life expectancy due to the development of biomedical science and technology and the improvement of personal hygiene in developed countries. To avoid irreversible global climate change, it is necessary to quickly transition from the current fossil fuel-based economy to a zero-carbon renewable energy-based economy that does not emit GHGs. To achieve this goal, the dairy and livestock industry, which generates the most GHGs in the agricultural sector, must transition to using low-carbon emission production methods while simultaneously increasing consumers' preference for low-carbon diets. Although 77% of currently available arable land globally is used to produce livestock feed, only 37% and 18% of the proteins and calories that humans consume come from dairy and livestock farming and industry. Therefore, using edible insects as a protein source represents a good alternative, as it generates less GHG and reduces water consumption and breeding space while ensuring a higher feed conversion rate than that of livestock. Additionally, utilizing the functionality of medicinal insects, such as silkworms, which have been proven to have certain health enhancement effects, it is possible to develop functional foods that can prevent or delay the onset of currently incurable degenerative diseases that occur more frequently in the elderly. Insects are among the first animals to have appeared on Earth, and regardless of whether humans survive, they will continue to adapt, evolve, and thrive. Therefore, the use of various edible and medicinal insects, including silkworms, in industry will provide an important foundation for human survival and prosperity on Earth in the near future by resolving the current two major problems.

Background: Major pulmonary resection after neoadjuvant concurrent chemoradiation therapy (nCCRT) is associated with a substantial risk of postoperative complications. This study investigated postoperative complications and associated risk factors to facilitate the selection of suitable surgical candidates following nCCRT in stage IIIA-N2 non-small cell lung cancer (NSCLC). Methods: We conducted a retrospective analysis of patients diagnosed with clinical stage IIIA-N2 NSCLC who underwent surgical resection following nCCRT between 1997 and 2013. Perioperative characteristics and clinical factors associated with morbidity and mortality were analyzed using univariable and multivariable logistic regression. Results: A total of 574 patients underwent major lung resection after induction CCRT. Thirty-day and 90-day postoperative mortality occurred in 8 patients (1.4%) and 41 patients (7.1%), respectively. Acute respiratory distress syndrome (n=6, 4.5%) was the primary cause of in-hospital mortality. Morbidity occurred in 199 patients (34.7%). Multivariable analysis identified significant predictors of morbidity, including patient age exceeding 70 years (odds ratio [OR], 1.8; p=0.04), low body mass index (OR, 2.6; p=0.02), and pneumonectomy (OR, 1.8; p=0.03). Patient age over 70 years (OR, 1.8; p=0.02) and pneumonectomy (OR, 3.26; p<0.01) were independent predictors of mortality in the multivariable analysis. Conclusion: In conclusion, the surgical outcomes following nCCRT are less favorable for individuals aged over 70 years or those undergoing pneumonectomy. Special attention is warranted for these patients due to their heightened risks of respiratory complications. In high-risk patients, such as elderly patients with decreased lung function, alternative treatment options like definitive CCRT should be considered instead of surgical resection.

The aim of this study is to look into the influential factors on the care-workers-perceived job stress level according as the elderly-perceived satisfaction varies depending on care workers' organizational characteristic & attitudes toward work, and there's necessity of reducing their job stress. Hereupon, this study, targeting the care workers at domiciliary visit care centers in Seoul district, analyzed the influential factors of organizational factors consisting of the sub-factors, such as job autonomy, compensation, education and development, members' interrelationship, etc. on the perception level of job stress. As a result of analysis, it was found that the shorter their working hours, the more their salary, the more guaranteed their job autonomy, and the better their interrelationship is, the care workers at a domiciliary visit care center had a positive perception of job stress. Accordingly, the operators of domiciliary visit care centers are requested to have a lot more concerns for diverse forms of improvements which can not only improve care workers' working conditions, such as daily working hours and a pay level but also promote a sense of fellowship between members; in addition, it is hoped that the operators should improve the organizational environment so that care workers can freely carry out their assigned business with a sense of responsibility rather than relying on control and regulation.
