This thesis explores the relationship between self-construal and online communication pattern. The Internet has changed human-to human communication. This study was to analyze how the self-construal was appeared and what relationship self-construal had with several variables: the motivation of the on-line community member, the on-line community's character, the communication behavior, the level of relationship between on-line community members- in on-line communities. The data was collected through the on-line survey research(N=79) and off-line survey research(N=255). The results lead us to conclude that the self-construals in on-line communities reflect two factors, which is similar to the off-line community. Nevertheless, self-construals in on-line communities are more complicated. In addition, uniqueness of self-construals which is the tendency to express the self and think connection with others critical is the important factor in on-line communities' communication. It is also central that the impact of self-construals on communication behavior is significant. I think this study was a small touch to explore cyber communication applying to self-consturals. And I hope this small touch would spread out and help to understand human communication as well as cyber communication.
Recently, an interest on how to moderate parenting stress of grandparents is rising according to rising depression of grandparents of grandparents and grandchildren family(GGF) because of parenting stress So, this study tried to analyze moderating effects by setting social support and stress coping behaviors as moderator variable in order to know how much parenting stress of grandparents would influence their depression. For this purpose, we selected 369 cases of grandparents who were being provided social welfare service and to 334 cases out of them, did multigroup analysis using hierarchical regression analysis and structural equation model under spss Vor. 19.0 program. Followings are the results. First, the more parenting stress was high, the more depression high. But when social support was high, parenting stress low. And the more parenting stress was high, faith dependence, negative emotional expression and passive evasion as stress coping behaviors also high while problem reestablishment low. Second, emotional support, information support, and material support as social support had moderating effects in which parenting stress influenced depression while appraisal support had not. Third, faith dependence and low passive evasion as stress coping behaviors had moderating effects in influence of parenting stress to depression while problem reestablishment has not. On the one hand, emotional expression was meaningless in explaining moderating effects in connection with parenting stress. Through these, we draw a social welfare practical implication that could lift moderating effect of social support and stress coping behavior in between parenting stress and depression of grandparents of grandparents and grandchildren Family.
This study empirically analyzed the effect of perceived injustice on service recovery measures proposed by online food delivery service (OFDS) companies on consumer disappointment. This study adopted interaction justice, information justice, procedural justice, and distributive justice as sub-variables of justice perception based on the justice theory. In addition, the differences by generation (MZ generation and other generations) were examined in the relationship between negative word-of-mouth behavior and switching intentions due to service recovery failure. An online survey was conducted targeting 250 adult consumers in the U.S for the empirical analysis of this research model. The results of the data analysis demonstrated that negative perceptions about the procedural justice and distributive justice among the service recovery strategies had a positive effect upon the consumer's disappointment. Furthermore, it was confirmed that the consumer's disappointment due to the perceived injustice of the service recovery strategy had a positive effect on the consumer's negative word-of-mouth behavior and switching intentions. The verification results of the moderation effect in the relationship between negative word-of-mouth behavior and switching intention, it was found that the younger the age(MZ generation), the higher the possibility of causing dysfunctional behavior. This study expands the scope of related research by presenting a new perspective on the justice perception in the service recovery process by verifying dysfunctional behavior of consumers caused due to the failure of the service recovery strategy. It is believed that the results of this study will be used as basic data for the establishment of practical strategies for OFDS companies to prevent double defection of their customers.
Since North Korea has used terror crime as a means of unification under communism against South Korea, South Korea has been much damaged until now. And the occurrence possibility of terror crime by North Korean authority is now higher than any other time. The North Korean terror crimes of Kim Il Sung era had been committed by the dictator's instruction with the object of securing governing fund. However, looking at the terror crimes committed for decades during Kim Jung Il authority, it is revealed that these terror crimes are expressed as a criminal behavior because of the conflict to accomplish the power and economic advantage non powerful groups target. This study focused on the power conflict in various causes of terror crimes by applying George B. Vold(1958)'s theory which explained power conflict between groups became a factor of crime, and found the aspect by ages of terror crime behavior by North Korean authority and responding plan to future North Korean terror crime. North Korean authority high-ranking officials were the Labor Party focusing on Juche Idea for decades in Kim Il Sung time. Afterwards, high-ranking officials were formed focusing on military authorities following Military First Policy at the beginning of Kim Jung Il authority, rapid power change has been done for recent 10 years. To arrange the aspect by times of terror crime following this power change, alienated party executives following the support of positive military first authority by Kim Jung Il after 1995 could not object to forcible terror crime behavior of military authority, and 1st, 2nd Yeongpyeong maritime war which happened this time was propelled by military first authority to show the power of military authority. After 2006, conservative party union enforced censorship and inspection on the trade business and foreign currency-earning of military authority while executing drastic purge. The shooting on Keumkangsan tourists that happened this time was a forcible terror crime by military authority following the pressure of conservative party. After October, 2008, first military reign union executed the launch of Gwanmyungsung No.2 long-range missile, second nuclear test, Daechung marine war, and Cheonanham attacking terror in order to highlight the importance and role of military authority. After September 2010, new reign union went through severe competition between new military authority and new mainstream and new military authority at this time executed highly professionalized terror crime such as cyber/electronic terror unlike past military authority. After July 2012, ICBM test launch, third nuclear test, cyber terror on Cheongwadae homepage of new mainstream association was the intention of Km Jung Eun to display his ability and check and adjust the power of party/military/cabinet/ public security organ, and he can attempt the unexpected terror crime in the future. North Korean terror crime has continued since 1980s when Kim Jung Il's power succession was carried out, and the power aspect by times has rapidly changed since 1994 when Kim Il Sung died and the terror crime became intense following the power combat between high-ranking officials and power conflict for right robbery. Now South Korea should install the specialized department which synthesizes and analyzes the information on North Korean high-ranking officials and reinforce the comprehensive information-collecting system through the protection and management of North Korean defectors and secret agents in order to determine the cause of North Korean terror crime and respond to it. And South Korea should participate positively in the international collaboration related to North Korean terror and make direct efforts to attract the international agreement to build the international cooperation for the response to North Korean terror crime. Also, we should try more to arrange the realistic countermeasure against North Korean cyber/electronic terror which was more diversified with the expertise terror escaping from existing forcible terror through enactment/revision of law related to cyber terror crime, organizing relevant institute and budget, training professional manpower, and technical development.
This study attempted to explore how online game is endowed new meaning and function and changed into totally different product in result by recognition and consuming behavior(game activity) of game users. The subjects of this study are famous Internet based online games called 'Lineage' and 'EverQuest'. These two online games are physically similar games. Both are MMORPG and community-based games. While Lineage became a cyber world as a part of the real world, EverQuest was a game product. This study explored the recognition of garners about game world and different consuming behavior pattern(game activity pattern) in game world made by different recognition of online game. The result from exploring the differences in the recognition of game world showed Lineage garners regarded Lineage world as another living space or a part of real world they can explore and express psychological need and self-identity or self-image and live through diverse activities. But EverQuest garners regarded EverQuest as a product for experience of fantasy world. The result from comparing the game consuming behaviors showed that different recognition of game world made the differences in the game consuming behavior. The results of the present study supported that the recognition of consumers about digital images or content poducts like online game can be different by the value and experience of consumer, and the different recognition make the different consuming behavior of similar or same products. The results supported that the meaning and value of digital images or digital content are endowed by consumers.
There have been many previous studies about an effect of anonymity on self control behavior. However the previous studies are on the aspect of results such as the usefulness, the problems of cyber crime or a lack of trust by anonymity. This study identifies the accurate definition of the objective technical anonymity and subjective social anonymity. And it reveals the relationship among technical anonymity, social anonymity, community tie, and self control as an effect of anonymity. The result of survey shows that technical anonymity affects self control through social anonymity and the relationship between technical and social anonymity is affected by community tie. This study presents how the anonymity affects individual behaviors. So it can be used as a reference to the policy on anonymity of the internet.

National-scale industrial control systems for gas, electric power, water processing, nuclear power, and traffic control systems increasingly use open networks and open standards protocols based on advanced information and communications technologies. The frequency of cyberattacks increases steadily because of the use of open networks and open standards protocols, but follow-up actions are limited. Therefore, the application of security solutions to an industrial control system is very important. However, it is not possible to apply security solutions to a real system because of the characteristics of industrial control systems. And a security system that can detect attacks without affecting the existing system is imperative. Therefore, in this paper, we propose an intrusion detection system based on packet analysis that can detect anomalous behaviors without affecting the industrial control system, and we verify the effectiveness of the proposed intrusion detection system by applying it in a test bed simulating a real environment.
The purpose of this study was to investigate the rate of pregnancy, abortion, delivery and contraceptive use and the relationship between the related factors and the early coitus among Korean teenagers. Method: The subjects of this study were 12,733 teenagers age 13-19 years in 7 major cities and 9 provinces in Korea. Data was collected from 2 Oct., to 28 Oct., 2000 and analyzed by using SPSS 10.0 Program. Results: The results showed pregnancy rate 4.5%, delivery rate 0.5%, abortion rate 0.4%. Adolescent girls who experienced coitus relatively went to vocational school, coeduaction school, night school in the general characteristics (p=0.000). Adolescent girls who experienced coitus tend to go to video room (18.5%), go the singing room (60.7%), the bar (54.8%), petting with the partner during the dates. There were overlapping juvenile delinquencies such as drinking (89.2%), pornography (65.3%), bond inhalation (2.7%), leaving homes (43.7%), smoking (14.5%), cyber sex (70.8%), phone sex (12.9%). Adolescent girls who experienced coitus were more suffering from Wangtta (26.1%) than who had not. They showed significant positive attitudes toward coitus; such as feeling of excitement (6.6%), nature (37.9%), beauty (8.7%). On the other hand, they had more guilty (2.8%) than the inexperienced (p=0.000). The main factors relating to early coitus were 'to confirm love' (46.9%), 'afraid of rejection' (32.2%). They think the benefits of coitus were 'more intimacy with boyfriends' (20.6%), 'satisfaction of curiosity' (16.8%). The losses on coitus were 'worry about pregnancy' (73.7%) and 'unability to refuse sexual contacts' (28.7%) Conclusion: It could be concluded that it is necessary to plan different sex education programs according to general characteristics and delinquency behaviors of teenage girls in Korea.
Casting defects produced during the casting process seriously affect the mechanical properties of the resulting products, reduce the performance capabilities of the product, and also result in economic losses. Therefore, this paper mainly investigates the causes of defects and methods by which to reduce these defects stemming from molten metal flows in a runner system of the type widely used in the sand mold casting process. The flow characteristics of a molten alloy are difficult to observe during the actual casting process. For this reason, a water model was used to observe the flow in the casting process, and the flow in each case was recorded using high-speed cameras as part of the experimental process of this study. Several repetitive experiments were performed to improve the accuracy of the experimental results. The traditional casting system was modified according to the design rules proposed by Campbell, and the system was termed flow-adaptive gating system with a water model. Comparing the flow characteristics of traditional and adaptive gating systems with a water model shows that the bubbles in the water in the latter case are reduced more significantly than in the former case. A ceramic filter system was adapted to the flow-adaptive gating system to minimize the instability of the flow during filling, which occurs as the fluid velocity in the runner increases. In additional, the flow behavior with and without the filter system were compared. The water model system in this work was shown to be able to verify that the adaptation of the filter system brings improvements by stabilizing the flow and reducing the amount of bubbles in the runner system. Moreover, using the flow-adaptive runner system with the filter system leads to considerably stable flows in the runner system.
The implementation of Knowledge Management Systems does not guarantee knowledge sharing within organizations because knowledge sharing cannot be mandated. Although previous investigations have attempted to identify the motivational factors that facilitate knowledge sharing, the results of these studies cannot be easily applied across organizations due to the highly context specific nature of knowledge sharing. Societal culture, as well as organizational culture, affects knowledge sharing behavior. This is why successful knowledge sharing initiatives in the United States, for example, may prove ineffective in another country with a very different culture like China. Therefore, it is clearly important to understand the effects of different societal cultures on individuals' knowledge sharing behaviors. The principal objective of this study is to deepen our understanding about the impact of national culture on an individual's knowledge sharing intention. In order to achieve this goal, field data was collected from 197 employees from a variety of companies and organizations in two countries-Sweden and China. In a collectivistic culture such as China, anticipated reciprocal relationships have been shown to directly affect individuals' attitudes toward knowledge sharing, and the organizational climate has also been shown to affect subjective norms to a significant degree. Subjective norms can influence intentions to share knowledge indirectly through attitudes. In the highly individualistic culture of Sweden, one's sense of self worth and anticipated reciprocal relationships have been shown to profoundly affect individuals' attitudes towards knowledge sharing. In both countries, anticipated extrinsic rewards have been shown to exert no detectable effects on respondents' knowledge sharing attitudes, and subjective norms and organizational climate have been determined not to affect knowledge sharing intentions directly. Rather, in both cases, knowledge sharing intentions have been shown to be directly affected by attitude.
