Purpose: The aim of this study was to determine the factors that influence safe sexual behaviors of Korean young adults and identify differences by gender. Methods: This study aimed to determine which factors affected safe sexual behaviors based on the Theory of Planned Behavior. Data from 437 Korean young adults (in their 20s and 30s) were collected via online survey between January 3 and January 28, 2022. The questionnaire included items on sexual body image, sexual role perception, sexual attitudes, sexual socialization, sexual communication, and safe sexual behaviors. Structural equation modeling was performed. Results: According to the overall model fit of the hypothetical model, the final model was acceptable and explained 49% of safe sexual behaviors. Sexual attitudes (β=h-.70, p<.001) and sexual communication (β=.53, p<.001) directly affected safe sexual behaviors, and sexual role perception (β=.42, p<.001) indirectly affected safe sexual behaviors in a combined model. There were gender differences in the path from sexual attitudes (β=-.94, p<.001) and sexual communication (β=.66, p<.001) to safe sexual behaviors and from sexual body image (β=.27, p<.001) to sexual communication. Conclusion: Sexual attitudes and sexual communication were predictors of safe sexual behaviors, which differed by gender. Strategies that consider sexual attitudes, sexual communication, sexual role perception, and differences between men and women should be developed to improve the safe sexual behaviors of young adults.

The purpose of this study is to elucidate the emotion-understanding of Korean and thus to find out the importance of their way of self-expression by exploring the sentiment of Korean as regards their way of communications and self-expression therein. The method of this study is, being presumed the Cheong as the Korean's sentiment, to define the differences of concept between the Cheong traditionally used by them and the emotion employed in the psychology or the theory of consultation. And also, this study examines the aforementioned importance under the presumption that the Cheong in the Korean Culture makes it difficult that their emotion-understanding and self-expression to be perfect in their way of communication. In order to attain such purpose in this study, it investigates how they have seen the emotion-understanding and self-expression as to the way of communication throughout Carl G. Jung's psychology and T oegye Yi Hwang's theory of Human Mind and Nature respectively in the Occidental and Korean's Ideology. The most important thing, to be enlightened in this study, in the way of communication and self-expression are the emotion come from the big-Self(Self) in Carl G. Jung's psychology and that of the righteous sentiment from the human nature in T oegye Yi Hwang's theory of Human Mind and Nature. In conclusion, it reveals that our behavior, unvaryingly in the Orient and the Occident, is not the rational subject but the emotional one to be reacted only if our minds are attached mutually.

The main purpose of this study is to examine the implications of Habermas's Critical Theory, which has been considered as modern descendant of enlightenment thought, on the social work profession. The focus of this paper is a critical examination on expected perceptual and practical gain provided by communicative theory for the professional relations between social workers and clients. This paper proves that Habermas's theory has failed to sufficiently grasp the scope and functions of social work practice. First, in regard to perceptual gains, Habermas's theory commits some kind of reductionism which considers communicative behaviors as only and original one. It is likely to limit the scope and extent of the function and mission of social work into a kind of communication performed by humans with communicative ability. Second, in regard of practical gains, Habermas's theory does not provide detail procedure of power-free communication nor critical criteria to evaluate the degree of ideal speech situation. Without these ones, Habermas's critical theory might play a role of liberal conservatism, which is trying to replace the substantial contents with procedural formality. In sum, to be a adequate theoretical and practical framework for social work, Habermas's theory needs to combine additional humanitarian considerations into communicative paradigm with more detail requirements and preconditions for ideal speech situations between professional and clients.

The importance of common life safety is getting growth with modern society progress. This paper shows the extended way of assessment of danger that outcomes better result than the previous assessment based on crime frequency assessment. The assessment of this paper involves time, illusion degree, floating population and the personal condition. The evidence theory is not beneficial when the number of component increases, the assessment is more complex than before. This research solves the problem through the fuzzy theory adoption. This paper shows more advanced result that can express better danger awareness and get the adjective expression.

Instant Messenger is a communication tool which allows instant real-time connection between parties through Internet Compared to the most popular Internet communication tool. email. the messenger allows people to check network presence of other parties and to connect in real time among multiple parties. Mostly due to the convenience it provides. use of instant messengers has increased tremendously not only for personal purpose but also for business purpose. However. firms are agonizing about the real impact of instant messenger usage among employees. whether the impact is positive or negative in terms of the productivity, Applying the theory of reasoned action (TRA) and technology acceptance model (TAM). this study sets UP perceived ease of use. perceived usefulness and cultural orientation of individuals as antecedents of adoption and use of the messenger application, Also. the impacts of messenger usage are measured as task productivity and intimacy among colleagues. This study presents several findings about the instant messenger, First. perceived ease of use. and usefulness play important roles in raising the adoption level of instant messenger. Also. culture propensity also maintains strong influence towards the actual usage of the messenger. Among cultural variables. innovativeness, supportiveness and outcome orientation reveal strong positive impacts on adoption and use of the messenger. On the dependent side. use of instant messenger seems to have a strong direct impact on task productivity as well as indirect impact through intimacy. Implications are discussed.

A longitudinal modal transmission-line theory(L-MTLT) to analyze the static and dynamic behavior of two-section distributed feedback (DFB) lasers is used. The characteristic impedance and equivalent propagation constant of DFB structure with active layer are derived from L-MTLT. A two-section DFB laser is analogous to a transmission-line network, in which each section is described by transmission-line block corresponding to the equivalent factors. The longitudinal resonant condition of DFB laser based on equivalent transmission-line network is used to reformulate the rate equations so that static and dynamic behavior of two-section DFB lasers with active layer is demonstrated and analyzed accurately.
