Background and objective: In the Republic of Korea, military service is mandatory. Some of new recruits have the stress from the special environment, which could cause psychological maladjustment. The military forces have operated education programs such as green camp and healing camp. The study was conducted to investigate changes in psychological and physiological stress by conducting forest healing activities along with plant scent treatment for soldiers participating in a green camp. Methods: A total of 52 soldiers were participated including maladjustment soldiers and those recommended by their military units to protect the unfit soldiers who participated in forest healing activities in the green camp. The programs that were certified by the Korea Forest Service between 2014 and 2019, and were applied for stress reduction and relaxation training were classified into stress-coping programs and forest experience programs. Post-hoc surveys and cortisol measurements were carried out. Results: Green camp soldiers experience and differences in the level of stress responses were found to be very statistically significant between the treatment and control groups. The techniques for coping with stress were not significantly different in the control group, and the treatment group showed statistically significant results. In addition, the results of analyzing changes in the concentration of cortisol and measuring physiological stress were very statistically significant in forest healing activities at 4 p.m. Conclusion: Once green camp soldiers face stressful situations, forest healing programs using forest plant scents for green camp soldiers can have positive responses and forest healing activities can reduce psychological and physiological stress responses, improving maladjustment behaviors caused by stress and positively affecting the reduction of cortisol.

OBJECTIVES: The aim of effective data quality control and management is to minimize the impact of errors on study results by identifying and correcting them. This study presents the results of a data quality control system for the Korea HIV/AIDS Cohort Study that took into account the characteristics of the data. METHODS: The HIV/AIDS Cohort Study in Korea conducts repeated measurements every 6 months using an electronic survey administered to voluntarily consenting participants and collects data from 21 hospitals. In total, 5,795 sets of data from 1,442 participants were collected from the first investigation in 2006 to 2016. The data refining results of 2015 and 2019 were converted into the data refining rate and compared. RESULTS: The quality control system involved 3 steps at different points in the process, and each step contributed to data quality management and results. By improving data quality control in the pre-phase and the data collection phase, the estimated error value in 2019 was 1,803, reflecting a 53.9% reduction from 2015. Due to improvements in the stage after data collection, the data refining rate was 92.7% in 2019, a 24.21%p increase from 2015. CONCLUSIONS: Despite this quality management strategy, errors may still exist at each stage. Logically possible errors for the post-review refining of downloaded data should be actively identified with appropriate consideration of the purpose and epidemiological characteristics of the study data. To improve data quality and reliability, data management strategies should be systematically implemented.

In the early stage of establishing New China, the government claimed to support a new socialist image of women liberated from feudalism. Thus, the ‘prostitutes’ had to be reborn as ‘workers who could make a living by themselves’ by working at productive labor. The works handling the alteration of prostitutes mostly show the rehabilitation through labor as a theme while the work Red Powder is mainly composed of a desire for material and erotism. The work Red Powder shows the ‘desire’ that was considered as a taboo in the socialist ideology of the time. By placing the ‘tabooed’ code such as ‘desire’ in front of the work, it is against the ideology that the new Chinese society was aiming for at that time. The realization of erotism between a prostitute Xiao e and a son of ruined upper class Lao pu of the characters includes the resistance to deviate from socialist ideology, which needs to be paid attention. The work Red Powder shows a beauty of tragedy and sorrow by focusing on the looks of characters who failed in adapting themselves to the new social structure of new China, and the devices like ‘taboo’ and ‘violation’ are playing the central role in this work. The characters of this work are the ones alienated from the time such as prostitute, disabled person, and surplus human. Both Xiao e who refused to work, and Lao pu who was living lethargically refused to be rehabilitated into socialist-type humans, which means they are the ones who already violated the social ‘taboo’ as the people who were ousted to the outside the boundary of state. Just as the women’s desire for consumption is usually connected to moral disorder and violation of sexual custom, Xiao e is also described as a morally-dissolute, extravagant, and femme fatale look. Her femme fatale aspect could be seen when she freely used her own sexual allure to get what she wanted. And due to her vanity and extravagance, her husband Lao pu embezzled the company’s public funds, and eventually, faced a tragedy of being shot to death. Such a tragic ending for those two main characters who broke social ‘taboo’ not only means the failure of erotism, but also shows a discord between personal self and ordered society.

In the background aiming to organize neo-socialistic men in the early stage of founding the New China, the strong and full-scale prostitution prohibiting movement was carried out. The ‘prostitutes’ were located in an ambiguous point in which it was not clear if they were the objects of compassion and pity, or the objects of blame as the main culprit of pleasure and decadence. In this circumstance, the Chinese government of the time aimed to set the ‘prostitutes’ as the representative image of women who were reformed as an ideal socialistic image of women after getting out of the capitalistic class. Defining the prostitution as a class issue caused by bourgeois men who were exploiting proletarian women, the ‘prostitutes’ were regarded as the suppressed ruled, and the ‘prostitutes’ liberation’ from the prostitution meant the ‘liberation’ from the institutional oppression. Lu Wenfu’s Deep in the Alley is a representative novel work handling the reformation and rehabilitation story of a ‘prostitute’. In the plot of Deep in the Alley, Xu Wenxia who degenerated into a ‘prostitute’ due to financial hardship at home when she was only 16, was reformed as a laborer and also obtained her love through the reforming education after the foundation of New China. The ‘productive labor’ is working as an important medium and device that bring the rehabilitation and salvation to Xu Wenxia who used to be a ‘prostitute’. Even though Xu Wenxia used to be a ‘prostitute’ in the past, she gets a new life and also obtains the psychological freedom and happiness by actively participating in the reforming movement led by the government. Besides the ‘productive labor’, the ‘love and romantic relationship’ also works as an important medium and device that bring the rehabilitation and salvation to Xu Wenxia. This work realizes the meanings of love by presenting an ideal male character called Zhang Jun who leads Xu Wenxia to become a professional electrician. The love between Xu Wenxia and Zhang Jun is described as a path toward the rehabilitation and salvation, instead of the truth revealing the passionate and private emotion of individuals. This shows that Xu Wenxia needs an assistant who could ideologically and vocationally lead her to get the salvation and rehabilitation, which also means that it is impossible for her to reach the rehabilitation and salvation by herself.

With the development of next-generation automobile technologies such as autonomous driving and electric vehicles, many open data portals have obtained automobile industry data which is needed to train a machine learning models. However, most portals only deal with general information such as data formatting and administrator information, but do not provide users with the quality information of the data they need. In this paper, we study data quality analysis methods for open data portals. We explore internationally used data quality analysis indicators and select indicators that open data portal administrators can provide to users without additional metadata. In addition, we discuss how to apply the selected evaluation indicators to the real automobile industry open data portal and visually deliver quality analysis information to users.
