  • An attempt has been made in this article to discuss the fundamentals of technical analysis of the stock market. A retail investor or trader may not have the wherewithal to source that kind of information. Technical analysis requires a candlestick chart only. Most of the brokers in India provide charting solutions as well. Studying the price action of a security or commodity or Forex generally indicates a price pattern. Prices react at certain levels and widely known as support and resistance levels. Since whatever is happening with the price of the security is considered to be a part of a pattern or cycle which has already played out sometime in the past, these studies help a keen technical analyst to identify with certain probability, the future movement of the price. Study of the candlestick patterns, price action, volumes and indicators offer the opportunities to identify a high probability trade with probable target and a stop loss. A trader or investor can take high probability trade or position and control only her losses.

  • Background: Studies on the association between occupational stress and depression have been frequently reported. However, the cross-sectional designs of studies limited insight into causal associations. In this study, we investigated the longitudinal association between occupational stress and new-onset depression among employees in a single manufacturing plant. Methods: The annual health checkup data of employees at a manufacturing plant in Korea were collected. A total of 1,837 male employees without depression who completed a health checkup during two consecutive years were included. Occupational stress was measured using a short form of the Korea Occupational Stress Scale (KOSS-SF), and depression was assessed using a Patient Health Questionnaire-2. The association between occupational stress change over the two years and newly developed depression was investigated using two logistic regression models. Results: Across all sub-factors of KOSS-SF, employees who reported increased occupational stress had a higher risk of new-onset depression. Newly developed depression was significantly associated with job demand (odds ratio [OR]: 4.34; 95% confidence interval [CI]: 2.37-7.96), job insecurity (OR: 3.21; 95% CI: 1.89-5.48), occupational climate (OR: 3.18; 95% CI: 1.91-5.31), lack of reward (OR: 2.28; 95% CI: 1.26-4.12), interpersonal conflict (OR: 2.14; 95% CI: 1.18-3.86), insufficient job control (OR: 1.93; 95% CI: 1.05-3.56), and the organizational system (OR: 1.84; 95% CI: 1.01-3.36). Conclusions: For every sub-factor of the KOSS-SF, occupational stress increase and persistent high stress were associated with the risk of developing new-onset depression. Among the seven sub-factors, job demand had the most significant effect. Our results show that occupational stress should be managed to promote employee mental healthcare.

  • Background: At present, no short standard questionnaire exists for assessing and comparing major work organization hazards in the workplaces of the United States. Methods: We conducted a series of psychometric tests (content validity, factor analysis, differential-item functioning analysis, reliability, and concurrent validity) to validate and identify core items and scales for major work organization hazards using the data from the 2002-2014 General Social Surveys (GSSs), including the Quality of Worklife (QWL) questionnaire. In addition, an extensive literature review was undertaken to find other major work organization hazards which were not addressed in the GSS. Results: Although the overall validity of the GSS-QWL questionnaire was satisfactory in the psychometric tests, some GSS-QWL items of work-family conflict, psychological job demands, job insecurity, use of skills on the job, and safety climate scales appeared to be weak. In the end, 33 questions (31 GSS-QWL and 2 GSS) were chosen as the least, but best validated core questions and included in a new short standard questionnaire (called the Healthy Work Survey [HWS]). And their national norms were established for comparisons. Furthermore, based on the literature review, fifteen more questions for assessing other significant work organization hazards (e.g., lack of scheduling control, emotional demands, electronic surveillance, wage theft) were included in the new questionnaire. Thus, the HWS includes 48 questions in total for assessing traditional and emerging work organization hazards, which covers seven theoretical domains: work schedule/arrangement, control, support, reward, demands, safety, and justice. Conclusions: The HWS is a short standard questionnaire for assessing work organization hazards which can be used as a first step toward the risk management of major work organization hazards in the workplaces of the US.

  • We tried to develop the school violence prevention program which focuses on the bystanders. In the context of school violence, most students are bystanders. They can either reinforce the violence or stop the violence. We hypothesized that the students who know their own temperament dimensions such as novelty seeking, harm avoidance, and reward dependence (Cloninger, 1994) will show more tendencies to defend victims from school violence when they learned the methods to prevent school violence in accordance to their temperament dimensions. 351 Korean middle school students participated the 4 sessions of school violence prevention program. The students completed the questionnaires to identify their own behavior in school violence situations. In the experimental group(temperament group), students learned the methods to help the victims that suits with their own temperaments. Whereas, the comparison group just attend the class regardless of their temperaments. Both groups showed significant increase in the trend of defending the victims. However, the temperament group showed more tendency to protect/defend the victims than the comparison group when they faced with school violence. These results show that students can learn the methods of defending victims from school violence more easily by knowing their own temperament dimensions, and can be the prepared and the effective defenders.

  • Sonobuoys are disposable devices that utilize sound waves for information gathering, detecting engine noises, and capturing various acoustic characteristics. They play a crucial role in accurately detecting underwater targets, making them effective detection systems in anti-submarine warfare. Existing sonobuoy deployment methods in multistatic systems often rely on fixed patterns or heuristic-based rules, lacking efficiency in terms of the number of sonobuoys deployed and operational time due to the unpredictable mobility of the underwater targets. Thus, this paper proposes an optimal sonobuoy placement strategy for Unmanned Aerial Vehicles (UAVs) to overcome the limitations of conventional sonobuoy deployment methods. The proposed approach utilizes reinforcement learning in a simulation-based experimental environment that considers the movements of the underwater targets. The Unity ML-Agents framework is employed, and the Proximal Policy Optimization (PPO) algorithm is utilized for UAV learning in a virtual operational environment with real-time interactions. The reward function is designed to consider the number of sonobuoys deployed and the cost associated with sound sources and receivers, enabling effective learning. The proposed reinforcement learning-based deployment strategy compared to the conventional sonobuoy deployment methods in the same experimental environment demonstrates superior performance in terms of detection success rate, deployed sonobuoy count, and operational time.

  • The rapidly changing security environment and technological innovations of the 21st century present new challenges to military organizations. Particularly, as the MZ generation, comprised of Millennials (born 1981-1996) and Generation Z (born 1997-2012), emerges as the primary workforce in the military, traditional military personnel management methods are being called into question. The MZ generation, as digital natives, are technologically proficient, prioritize personal growth and quality of life, and prefer horizontal communication and participation. The purpose of this study is to reestablish talent acquisition and retention strategies for military organizations, considering the characteristics and demands of the MZ generation. To this end, we analyzed advanced talent management techniques from the corporate sector and explored ways to apply them to the unique context of military organizations. Additionally, by examining the current status and challenges of the Korean military, we attempted a balanced approach that considers both global trends and Korea's specific circumstances. The research results suggest various strategies including career development programs, cultural innovation, improvement of reward systems, participatory decision-making, enhancement of digital competencies, and creation of flexible work environments. These strategies are expected to improve the efficiency and competitiveness of military organizations while simultaneously enhancing job satisfaction and organizational commitment among MZ generation service members.

  • Objectives : Recently, many authors investigated the relation of temperament and character to seasonality and the genetic factors in seasonality and personality. In this study, we investigated the relation between personality structure obtained from the psychobiological Temperament and Character Inventory (TCI) and self-reported seasonal variations in mood and behavior measured by the Seasonal Pattern Assessment Questionnaire (SPAQ). Methods : 600 high-school students who live in Seoul of Korea, were participated in this study. Subjects were surveyed with the Korean translation of the SPAQ of Rosenthal, an instrument for investigating mood and behavioral changes with respect to the seasons of the you. Korean version of the TCI of Cloninger was also used for assessment of personality. Results : Female students were significantly higher scores on harm avoidance, reward dependence, and cooperativeness than male students who had significant higher scores on persistence and self·transcendence than the formers. GSS were showed positive correlation with harm avoidance and self-transcendence, and negative correlation with cooperativeness and self-directedness. By employing logistic regressions, the regression coefficients of SAD were significantly negative in SD, and positive in ST. Also, the regression coefficients of S-SAD were significantly negative in CO, and positive in ST. Those with GSS at least 11 were significantly higher mean ST values compared to the remaining individuals, and those with worst in winter were significantly lower mean CO values compared to the remaining individuals. Those who considered the seasonality as a problem at least to a moderate degree were associated with high HA and ST. Conclusion : We add the evidence that the seasonality is related to the temperament and character. Although there have been many reports about the seasonality in relation to the temperament and character in foreign countries, there has been very limited report from Korea before. We hope that this result would be a helpful in the clinical field in Korea.

  • Purpose: This study determined the relationships between maternal comprehensive feeding practices (CFP) and dietary practices of preschool children. Methods: Participants of the study were 227 mothers of children aged 3 to 5 years attending daycare centers and kindergartens in Seoul and Gyeonggi Province of Korea. The Comprehensive Feeding Practices Questionnaire was used to assess the maternal feeding practices. The Nutrition Quotient for Preschoolers (NQ-P) was measured to evaluate dietary practice and diet quality of children. Results: The balance of NQ-P for children was positively correlated with the modeling, restrictions for weight control, encouragement of balance and variety, pressure, and involvement among maternal CFP. Moderation of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement among maternal CFP. However, it was negatively correlated with emotion regulation, food as a reward, and child control in maternal CFP. Among maternal CFP, the environment of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement, and it was negatively correlated with emotion regulation. As a multiple regression analysis, maternal CFP that positively predicted balance of NQ-P indices were restricted for weight control, pressure, and involvement. Among maternal CFP, encouragement of balance and variety, and environment were positive predictors, while food as a reward, and child control were negative predictors for the moderation of NQ-P. Items of maternal CFP positively predicting environmental factors of NQ-P were monitoring and environment. Conclusion: Mothers are recommended to practice dietary guidance to their children, such as monitoring, modeling, teaching about nutritional information, recommendation of balance and diversity, healthy eating environment, and participation in meal plan and preparation, while they are advised not to conduct any adverse dietary guidance such as emotional control, compensation with food, child control, and food coercion.

  • Purpose: This study intended to identify personality factors and related problematic behaviors of adolescents who drink alcohol in order to provide basic data for developing nursing programs. Methods: The data were collected from October to December 2002 from 1.080 high school students in Seoul. The Revised Cloninger's Tri-dimensional Personality Questionnaire (TPQ) was used to measure their personalities. The alcohol expectancy was measured using the tool revised by Cho (1999) and stress levels were measure using a stress tool revised Cho (1998). The data were analyzed with SPSS Windows using Chi square test. independent t-test. and logistic regression analysis. Results: 1. The percentage of fathers who drank was 79.8%. mothers. 54.3%. and friends. 54.3%. The alcohol expectancy averaged 6.36 while the stress levels were 132.79. 2. It was found that there are significant differences (p<.001) in problematic drinking behaviors according to the following variables: second year high school students among all grade variables, more monthly pocket money for the amount of money variables, the group of students who smoked in the case of the variable related to smoking, spending more time using the Internet for the Internet use variable, and having friends who drink 65.6% for the friend variable. The alcohol expectancy scale of those students who showed problematic drinking behaviors was higher than that of those who did not. There are four family-related stress subscales, and there was a significant difference among them (p<.05). Among the personal characteristics, the group who displayed problematic drinking behaviors seeks new experiences and reward dependence more than the group who did not exhibit those behaviors, and there were significant differences between the two groups (p<.001). 3. When the socio-demographic and drinking-related factors were controlled, the tendency of seeking new experiences increased the risk of problematic behaviors 1.07 times (p<.05). Compared to the non smoking group, the smoking group was found to have a 5.06 time (p<.001) greater risk of displaying problematic drinking behaviors. In comparison with the non drinking group, the drinking group was also found to have a 5.31 time (p<.001) greater risk of exhibiting problematic drinking behaviors. The group with high alcohol expectancy scores was significantly different from the group with the no alcohol expectancy, showing a 1.26 time (p<.00l) greater risk of problematic drinking behaviors. Conclusions: Based on these results, the problematic drinking behaviors were connected with alcohol expectancies, friends and personality types. Therefore, we should develop an alcoholic prevention program for adolescence considering the above results.
