As the online game industry has been growing rapidly, more and more malicious activities to gain economic benefits have been reported as well. Game bot is one of the biggest problems in the online game industry. So we proposed a bot detection method based on the ERG theory of motivation for the first time. Most of the previous studies focused on behavior-based detection by monitoring patterns of the specific actions. In this paper, we applied the motivation theory to analyze user behaviors on a real game dataset. The result shows that normal users in the game followed the ERG theory of motivation in the same way as it works in real world. But in the case of game bots, the theory could not be applied because the game bot has specific reasons, unlike normal game users. We applied the ERG theory to users to distinguish game bot users from normal users. We detected the game bot with high accuracy of 99.78% by applying the theory.

The elderly in rural areas are faced with the dilemma of poor community environment, weak social communication ability and insufficient pension knowledge reserve. In addition, due to the serious shortage of social security facilities in rural areas and medical resources, the elderly are struggling, and the suicide rate is far higher than that in urban areas. In order to make the elderly have a comfortable pension environment and face the increasingly serious aging problem with a positive attitude, this paper takes the community environment of the Baima Tibetan elderly in Tielou Township, Gansu Province as the research object of aging transformation. First of all, literature data were used to carry out research on the aging transformation in rural areas. On the basis of sorting out previous research topics, ERG theory was determined as the guide. Secondly, the research methods of on-site investigation, interview and other research methods are adopted to investigate the number of left-behind elderly people in this area, and classify them according to the national standards. At the same time, the image of the current situation of the community environment of the elderly. Finally, combined with the ERG theory, the transformation design of the elderly living environment is implemented, mainly from the three aspects of survival, mutual relationship and growth.

In this study, the multiplicity of synchronous online class discussion activity is explored at conceptual level. From the cultural-historical activity theory (CHAT), each utterance may be considered as a product of the activity system. Alderfer's ERG theory is employed as another theoretical framework for the study. Based on the subject's existence, relationship, growth needs, their class discussion activities constitute four different dimensions: physical/biological, cultural/institutional, social/relational, and cooperative knowledge construction. It is inherent in individual activities and has a different arrangement according to their interests and situations, and at the same time acts as a factor of cooperation and competition among the participants. Through this, collective discussion activities represent complex and dynamic development patterns.

Purpose: The purpose of this study was to explore the components and nature of happiness in middle-aged women in Korea. Methods: Thirty middle-aged women living in metropolitan Seoul and Gyeonggi and Chungcheong provinces agreed to participate in this study. The data were collected through in-depth interviews with the participants in one-on-one settings. The data were analyzed qualitative using Colaizzi's method of phenomenology. Results: The three theme clusters were extracted from the raw data, along with 13 themes and 138 meaningful sentences and phrases. The three happiness theme clusters in middle-aged women were "live healthy for stability," "rule one's mind for harmony," and "activate hopes for self-esteem." The first theme cluster included healthy life, economic stability, physical youth, and positive thought. The second theme cluster included that harmonious family, ruling of mind, my position as invisible person in social relationships, and precious relationships to support. The last theme included the center of one's life is oneself, a sense of accomplishment, self-improvement, recognition of one's worth and rest for one self. The three theme clusters were associated with the existence, relatedness, and growth (ERG) of ERG areas, respectively. Conclusions: We conclude that the core components of happiness in middle-aged women are to live healthy and mind-ruled and activate hope. The nature of happiness is egocentric stability in middle-aged women. The results suggest that theme clusters might be used to develop a scale for measuring happiness in middle-aged women. This will be helpful to assess the psychosocial status of middle-aged women in Korea.

This exploratory study which applied environmental scanning method to analyse a change in a future society tried to diagnose a reaction ability of our education system for the change in the future society. In addition, the study tried to explore an adequate direction for Home Economics Subject to be an mandatory subject continuously toward the change in the future society. Main changes in the future society can be expected as 1) demographic change due to low birth rate and aging society, 2) an increasing threat of a human living environment due to unexpectable natural disasters and accidents, 3) a radical progress into a ubiquitous computing environment led by AI, 4) an advent of a borderless economic society and a change for jobs, 5) a change in North Korea, and so on. Our education system which mostly concentrates on education to develop constructive intelligence by halving the society and schooling as yet, however, is diagnosed as it has a paradox that can not understand an emotional competency as a target for studying. Home Economics Subject is worth as the subject that can exactly complement a blind spot of our education system which can not respond to the future society adequately. This is because Home Economics Subject has had a characteristic as a 'Subject of Life' traditionally that has dealt with an overall 'life' of human beings, and the characteristic is favorable to develop human practical intelligence. Thus, because the 'life' is the main point of Home Economics Subject, it has the characteristic as a 'Subject of Happiness' which is the most effective method to develop a tendency to appreciate, a sense of empathy, and lots of pro-social behaviors that are important capacities to seek for happiness. As Alderfer's ERG Theory is to understand human beings' behavior based on the satisfactory of human beings' hierarchical desires, it is suggested as an adequate frame for the theory to restructure the characteristic of Home Economics Subject which develops the 'capacity to seek for happiness' by focusing the 'life', into core concept and core capacity of curriculum. A follow-up study should make a connection between ERG Theory and core concept and core capacity of curriculum to explore how the theory can be reflected on Home Economics curriculum.

Das Ziel dieses Aufsatzes liegt darin, die Valenzkonzepte und Satzmodelle von Kalevi Tarvainen zusammenzustellen, und auf die dependenzielle kontrastive Beschreibung des Deutschen und der Muttersprache des Deutschlernenden einzugehen, und ihre Prinzipien und Probleme kurz zu betrachten. Prinzipiell eignet sich die Dependenzgrammatik ebenso gut fur den muttersprachlichen Unterricht des Deutschen wie $f\"{u}r$ den Unterricht des Deutschen als Fremdsprache. Die Grundkategorien der Dependenzgrammatik, d.h. die hierarchische Dependenzbeschreibung mit dem Verb als Ausgangspunkt, die Valenz, die $Erg\"{a}nzungs- und$ Angabestruktur des Satzes, sind an sich fur den Fremdspracheunterricht gut verwendbar. $Ausl\"{a}ndische$ Deutschlernende haben als Ausgangssprache ihre eigene Sprache, $f\"{u}r$ deren Beschreibung sich die $f\"{u}r$ die Zielsprache verwendete Grammatiktheorie auch eignen muss. $\"{U}berdies$ muss $f\"{u}r$ alle Fremdsprachen, die ein $Sch\"{u}ler$ lernt, dieselbe Grammatiktheorie verwendbar sein. Die Dependenzgrammatik hat gute Voraussetzungen, zu einer allgemeinen Theorie $f\"{u}r$ den Fremdsprachenunterricht zu werden. Beim Vergleich der Sprachen muss man als Tertium comparationis vom 'Gemeinten' ausgehen. Wenn die deutlich detinierbaren Inhalte nicht vorhanden sind, muss man von den Formen ausgehen. Beim Erlernen der deutschen $S\"{a}tze$ $k\"{o}nnen$ die Grundkategorien der Dependenzgrammatik, die Klassitizierung der $Erg\"{a}nzungen$ und die Satzmodelle des deutschen Verbs und Adjektivs dem Deutschlernenden $gro{\ss}e$ Hilfe leisten.

Two conformations of benzoic acid derivatives ($NH_2$, OH, H, F, Cl, CN, NO, $NO_2$) have been investigated at MP2, DFT and HF level using the 6-311++G(d,p) basis set. It was found that the cis isomers are more stable. Hydrogen bonding formation of benzoic acids has been estimated from stabilization energies. The calculated hydrogen-bonding energies of dimers showed a cooperative interaction in the cyclic ones. It was found that an electron-releasing group (ERG) into the phenyl rings resulted in the formation of more stable hydrogen bonding. Red shift of O-H bond was found from -565.3 to -589.3 for dimers. The natural bond orbital (NBO) analysis was applied to characterize nature of the interaction.

As Korea became one of the oldest countries in the world, successful aging emerged as an important issue to individuals as well as to society. This study aims to determine not only the Korean seniors' happiness and unhappiness factors but also the means to enhance their happiness and deal with unhappiness. We collected news articles related to the happiness and unhappiness of seniors with nine keywords based on Alderfer's ERG Theory. We then applied a topic modeling technique, Latent Dirichlet Allocation, to examine the main issues underlying the seniors' happiness and unhappiness. According to the analysis, we investigated the conditions of happiness and unhappiness by inspecting the topics based on each keyword. We also conducted a detailed analysis based on the main factors from topic modeling. We proposed specific ways to increase and overcome the happiness and unhappiness of seniors, respectively, in terms of government, corporate, family, and other social welfare organizations. This study indicates the major factors that affect the happiness and unhappiness of seniors. Specific methods to boost happiness and relief unhappiness are suggested from the additional analysis.

contrasting monsoon between 1993 and 1994 produced an interannual difference in hydrology. Theoretical water residence time (TWRT) in monsoon 1993 averaged 27 d, which was>3 months shorter compared to the TWRT in monsoon 1994. A dominant physical process influencing thermal stratification, water movement, and mixing regime was an interflow current in 1993. During summer 1993, river water plunged to mid-lake (location 27 km) and passed through the 10${\sim}$20m stratum of the reservoir, resulting in an isolation of epilimnetic lake water from advected river water. The interflow disrupted thermal stratification and produced a meta-hypolimnetic warming of >4$^{\circ}C$ downlake, thereby increased a mixing depth (>13 m). In contrast, during monsoon 1994 density currents were not observed and strong thermal stratification occurred in the entire reservoir, resulting in > 2 fold greater thermal resistance (8.2${\times}10^{5}$ erg)compared to 1993 (4.0${\times}10^{5}$ erg). This reservoir was identified as a typical warm monomictic reservoir which showed one mixis during early winter. The timing of overturn, however, differed between the two years as a result of distinct contrast in TWRT and thermal regime; overturn in 1993 occured about one month earlier relative to that in 1994. Hypolimnetic warming was predictable in this system; the variation in discharge accounted (Y = 4.35-0.06X+0.10X$^{2}$, p<0.0001)for 98% of the interannual variation in hypolimnetic temperature. Overall data suggest that thermal stability, the timing of fall overturn, and water residence time in this system are primarily regulated by the intensity of monsoon.

This study evaluates the poverty experiences of low-income single mothers according to the Capability Approach of Amartya Sen. In this approach, the capability to achieve the basic functionings of life, not income itself, is the criterion of poverty. 26 single mothers were interviewed using focus-group interviews and in-depth interviews. 21 functionings on the existence level, 18 on the relatedness level, and 15 on the growth level were found in the areas of work, health, food consumption, clothing, housing, child rearing, and leisure. The results of this study suggest that low-income single mothers can achieve only some of the existence level functionings with significant help from welfare services. They can scarcely achieve higher level functionings in any of these areas.
