Cyberloafing is as counterproductive behavior because it is the act of using internet for personal purposes which can affect employees' productivity, especially when done excessively (more than 4 hours a week). The objective of this study was to analyze whether gender and education level had significant effect on cyberloafing among generations in the workplace. From 267 respondents, gender was not found to have impact on cyberloafing because female and male respondents had the same frequency of low level cyberloafing. However, female had higher excessive cyberloafing than male. Gen Y had significant impact on the relationship between education and cyberloafing but Gen Y with diploma degree was revealed to have excessive cyberloafing. Furthermore, Gen X had started combining professional and personal lives throughout their daily lives. Hence, organizations should foster a culture of hard work by giving challenging job with clear target and worthy incentive but still implementing internet usage policy.

The best way to care senile dementia patients is understanding the nature of disease. Care-givers can't understand the patients because the patients can't properly communicate with care-givers. Thus, care-givers are supposed to find out ways to understand them in the nature of disease. From this view, there seems no exception in essential attitude of care-givers toward the patients. Without positive understanding the nature of disease and respecting patient's rights as a human even though they are badly disorder in their word and behavior. There seems no expectation for thousands quality of care-giving.

Reduced-scale experimental study was carried out on the heat flow behavior which flows under the sloped ceiling in underground fire. Temperature and flow velocity were measured to characterize the ceiling jet along the sloped stairway ceiling. The methanol fuel was used as a model fire source giving 2.2 and 3.4 kW, with changing the slope angle of stairway adopting of 15, 25, 35, and 45 deg. Based on the experimental data, excess temperature and velocity along the sloped stairway ceiling were examined which are usefully applicable to estimate the activating conditions of heat detector and sprinkler head mounted on the sloped ceiling. Excess temperature in upper exit of the sloped stairway was also examined to analyze the soffit which delays the smoke diffusion. The result shows that the activating conditions of heat detector and sprinkler in the sloped stairway ceiling have to be considered differently in a point of about 30 deg.

Spectrophotometric studies have been made on the solutions of elementary iodine in pyridine and quinoline, in the absence of light. The results shown that triiodide ion is produced in both solutions with different rates, and that triiodide ion behaves differently in both solutions. Iodine reacts slowly with pyridine, giving rise to triiodide ion, which is relatively stable in this solvent, hereas, iodine reacts rapidly with quinoline, forming triiodide ion, which interacts further with the medium at slow rate. It has been thought that the difference of the behavior of triiodide ion in both solutions may be due to the stronger basicity of quinoline than pyridine.

This study was initiated to investigate (1) whether consumers preferred a specific garment size labeling system and (2) whether consumer's demographic characteristics, clothing behavior, and body size affect their preference of size labeling systems. The survey of consumer's preferences for five size labeling systems included 443 women with 20 to 64 years of age. The result of the survey showed that the subjects' preferences of five size labeling sysems were different significantly. Subjects strongly preferred the old system rather than the revised systems. The subjects least preferred the system with pictogram(system D) and the system with description of the measuring methods of te control dimensions (system E). The subjects/ preference for various garment size labeling systems was different depending on their resident area, educational level, and body size. The garment size labeling system with more information on body measurements (system C) was preferred by the subjects living in the metro city area or subjects having difficulties on purchasing ready-to-wear garments giving reasonable fit. The simplest size labeling system (system A) was strongly preferred by the subjects of low educational level, or the subjects living in the small city.

Particulate nitride composites have been fabricated by sintering the compacted powder of AlN and 5 - 64.3 mol% $Al_2O_3$, with a small addition of $Y_2O_3$ ($Y_2O_3$/AlN, 1 wt%), in 1-atm nitrogen gas at $1650-1900^{\circ}C$. The composites were characterized in terms of sintering behavior, phase relations, microstructure and thermal shock resistance. AlN, 27R AlN pseudopolytype, and alminium oxynitride (AlON, $5AlN{\cdot}9Al_2O_3$) were found to existin the sintered material. Regardless of batch composition, the AlN-$Al_2O_3$ powder compacts exhibited similar sintering behavior; however, the degree of shrinkage commonly increased with increasing $Al_2O_3$ content, consequently giving high sintered bulk density. By increasing the $Al_2O_3$ addition up to ${\geq}50 mol%$, the matrix phase in the sintered material was converted from AlN or 27R to AlON. Above $1850^{\circ}C$, a liquid phase was formed by the reaction of $Al_2O_3$ with AlN, aided by $Y_2O_3$ and mainly existed at the grain boundaries of AlON. Thermal shock resistance was superior in the sintered composite consisting of AlON with dispersed AlN or AlN matrix phase.

Social networking services (SNS) have become a significant platform for Internet users to obtain knowledge and information. Users can share messages mutually via this platform. This kind of sharing enables users to exchange and gain useful information. However, in recent years, the crisis of stickiness has appeared in SNS, calling attention to the social network industry. Relevant professionals explain that the interest of users in sharing knowledge on SNS websites and applications may gradually decrease, eventually leading to users giving it because the platforms utilize simple and uninteresting methods to attract active participation from users. However, factors affecting the knowledge sharing on SNS websites and applications should be identified clearly through studies. Sina Weibo is one of the largest SNS platforms in the world, and studies on the factors affecting knowledge sharing of users could be valuable in addressing this issue. This paper establishes the theoretical analysis model of knowledge sharing in SNS sites and applications, analyzes the factors affecting knowledge sharing on these sites, and proposes the corresponding strategies to address the issues. Using questionnaire surveys on Sina Weibo users, this article will discuss the factors affecting knowledge sharing, and analyze these factors on SNS as well as improve the stickiness of users to achieve the aim of SNS platforms enabling the expansion of the range of users. The study will discuss theoretical foundations and the hypotheses that arise. The method of study will also be discussed. The study concludes with theoretical implications, practical implications, limitations, and future research opportunities. The results of this study could aid researchers in understanding the underlying reasons for social network activities as well as for SNS developers in improving SNS services.
