This study has attempted to investigate how subjects perceive changes of brightness and their visual comfort according to daylight responsive LED(Light Emitting Diode) dimming systems in the office with venetian blind. Two studies was conducted. First study is that how subjects perceive changes of brightness and their visual comfort depending on angle control method of the venetian blind while the workplane illuminance level is being maintained through daylight responsive LED dimming system. Second study is that how subjects perceive changes of brightness and their visual comfort depending on the amount of daylight penetrated into the building while the illuminance level is being maintained through daylight responsive LED dimming system. The results of this study could be proposed as basic data in the control of the venetian blind and LED lighting in consideration of their perception on changes of brightness and visual comfort.

This study reveals the perceptual role of stop release burst to Koreans' recognition of POA(place of articulation) and voicing in the English word-final stops. 10 Korean subjects participated in a perception experiment wherein the stimuli are prepared on the basis of the amount of acoustic information, which includes the release burst. The result shows that i) release burst plays an important role in the recognition of POA in the order of velar, alveolar, and bilabial stops, and ii) the release burst more enhances the correct recognition of voiceless stops than that of voiced stops. This result leads us to conclude that the role of stop release burst differs with respect to the POA and voicing of the stops, and it is possibly related to the different intensity of release in voicing and in each POA.

The personality types developed by Gustav Jung are frequently used to identify peopl's decision-making style, especially to determine which functions are dominant ones in the perception and the processing of information. In this paper, the Jungian typology is utilized to investigate if there are any systematic relations between an individual's personality type and her/his attitude toward risk. For this purpose, an experiment was conducted where 99 subjects, mostly students, participated in a computer-simulated horse racing game. Each subject's risk-seeking propensity was measured by the winning chance of the selected horse and the amount of stakes. The results of the experiment show that a decision-maker who is extrovert (E) is attitude and intutive(N) in perception of information is more likely to be risk prone than the introvert(I) and sensing(S) type. Feeling(F) function in information processing seems to induce more risk seeking attitude than thinking (T) function, but the statistical significance could not be found from the data, for this statement.

Many cases of information systems (IS) failure have still continued to be reported ever since computer-based information systems were introduced to process business transactions in the early 1950s. Because an enormous amount of budgets is currently invested on information technology in many organizations, failures and problems of information systems may serve as key culprits to serious business problems which will face the organizations. Thus, there have been a number of studies on IS failures which aimed to identify causes and reasons for such failures and reveal their inherent nature, Some studies developed conceptual frameworks to classify categories of diverse IS failure phenomena. However, little research performed an empirical study to investigate the underlying structure of IS failures perceived by IS professionals by measuring their perception. In this regard, the current study collected systems developers perceptual data towards IS failure phenomena to identify what constitute IS failure. The data was analyzed using a multidimensional scaling program and ten categories of problems were identified to constitute the IS failure structure, It was found that most categories were related to problems with users, hardware, and systems quality.

The purpose of this study was to examine interactive effects of gender idelogies on the amount of household work time and the perception of fairness in household work by the couples. The data were collected from 100 couples in Seoul and 142 in Taejon. The Major findings were as follows: Interactive effects of gender idelogies had an important role in explaining household work time and the perception of fairness by husbands. For men holding more egalitarian gender idelogies who were married to women being more egalitarian tend to perform more hours of household work. And husbands who had traditional gender ideologies percept relatively fair to the couples' division of household work. It was approved that wives had a primary role in the division of household work.

Social media has emerged as a major hub of engagement between brands and consumers in recent years, and allows user-generated content to serve as a powerful means of encouraging communication between the sides. However, it is challenging to negotiate user-generated content owing to its lack of structure and the enormous amount generated. This study focuses on the hashtag, a metadata tag that reflects customers' brand perception through social media platforms. Online users share their knowledge and impressions using a wide variety of hashtags. We examine hashtags that co-occur with particular branded hashtags on the social media platform, Instagram, to derive insights about brand perception. We apply text mining technology and network analysis to identify the perceptions of brand images among consumers on the site, where this helps distinguish among the diverse personalities of the brands. This study contributes to highlighting the value of hashtags in constructing brand personality in the context of online marketing.

The term and concept of "immortality" has garnered a considerable amount of attention worldwide. However, research on this topic is lacking, and the question of when the mind of a deceased individual survives death has yet to be answered. This research investigates whether morality and mind perception of the dead correlate with immortality. Study 1 measures the perceived immortality of people, who were good or evil in life. The results show that the perceived morality is related with the perceived immortality. Moreover, participants indicated the extent to which each person had maintained a degree of morality and agency/experience of the mind. Therefore, morality and mind perception toward a person are related to perceived immortality. In Study 2, participants were asked to read three essays on robots (good, evil, and nonmoral), and had to indicate the extent to which each robot maintains a degree of immortality, morality, and agency/experience of the mind. The results show that good spirits of a robot are related to higher scores of mind perception toward the robot, resulting in increasing tendency of perceived immortality. These results provide implications that the morality of humans and robots can mediate the relationship between mind perception and immortality. This work extends on previous research on the determinants of social robots for overcoming difficulties in human-robot interaction.

This paper analyzed health practices of students in an university in Chollabukdo Province. It attempted to study how many university students had what kinds of health practices. Furthermore, it tried to find out what are the major problems in health practice among university students. To study health practices of university students, this study sampled 1,469 students randomly. Many of the students had poor practices of teeth care. In tooth-brushing, many students (35.8%) brushed their teeth before breakfast in the morning. Most of the students (95% or more) visit dental clinic only when they had problem(s) in their teeth. For weights, there exists a great gap between perception and BMI (Body Mass Index), especially among female students. Among the female students who perceived their weights were above average, 96.4% of them were normal according to BMI. Many of the students were drinking greater amount of alcohol than safe amount suggested by the National Health and Medical Research Council of Australia. The proportion of the students drinking harmful or hazardous amount of alcohol were 79.5% of the male students and 74.9% of the female students. It suggests that health promotion fund or tax need to be levied on alcohol to frustrate unhealthful drinking. More than half (59.0%) of the male students and about 6.0% of the female students were smoking cigarettes. The smoking initiation ages were 17.8 for male and 18.2 for female students. It means that many of the students started smoking in their junior high or high schools. It implies that smoking prevention and smoking cessation programs need to be emphasized in these schools. For perception on sex, 27.8% of the male students and 60.9% of the female students thought to keep their virginity before their marriage. The female students were more conservative in perception on sex. The average number of sexual intercourses per year of male students was 17.0 times with their lovers, 7.9 times with prostitutes, and 7.0 times with maids. The female students had sexual intercourses 5.0 times with their lovers and 4.0 times with waiters per year. The proportion of students who had experience of sexual intercourse with homosexual partners was 1.0%. The finding this study was that the university students were vulnerable to poor health practices. It is suggested that public health intervention program be provided for university students to keep them in good healthy lifestyle.

The purpose of this study was to investigate the perception and utilization of salted seafood in Korean women. We also asked them about their opinions on how to increase the production range of popular salted seafood. Data were collected from 1,137 women and were analyzed with SAS 9.1 program. Women aged between 40 and 59 had higher positive perception of salted seafood than women aged between 20 and 39. The older age group (i.e. 40 to 59) believed that the production of salted seafood, such as like as Kimchi and soy sauce, should be globalized because of their taste and nutritional value. However, the younger age group (i.e. 20 to 39) had negative perceptions of salted seafood because of their unhygienic production and excess amount of salt. Women aged 50 and over used salted seafood frequently as a side dish or seasoning to make Kimchi, stew, or soup. The younger age group preferred to purchase a small package (200g or less) of salted seafoods from the grocery store instead of preparing it themselves. When purchasing salted seafood, they considered the taste, manufacturer, and expiration date. Finally, all interviewees agreed on the importance of salted seafood as part of traditional Korean cuisine, and wanted to see further local development. However, manufacturing and packaging processes need to be standardized, and hygiene and nutritional contents should be improved in order to achieve good quality local production. To succeed and develop high quality salted seafood, younger consumers need to be enticed with better nutritional value, taste, and hygienic production. Furthermore, the production range of popular salted seafood needs to be expanded beyond Kimchi and Soy Sauce. Hence new recipes are needed.

Thoracic outlet syndrome (TOS) is a combination of signs and symptoms caused by the compression of the vital neurovascular structure at the thoracic outlet region. It may stem from a number of abnormalities, including degenerative or bony disorders, trauma to cervical spine, fibromuscular bands, vascular abnormalities and spasm of the anterior scalene muscle. CPT (current perception threshold) is defined as the minimum amount of current applied transcutaneously that an individual consciously perceives. It enables quantification of the hyperesthesia that precedes progressive nerve impairment, as well as hypoesthetic conditions. We experienced a case of thoracic outlet syndrome caused by fibrosis of anterior scalene muscle. The patient was a 30 years old woman with a 3 years history of numbness on the ulnar side, progressive weakness and coldness of both hand, tiredness in the left arm, nocturnal pain in the left forearm, and pain in the left elbow, shoulder and neck. Conservative treatment, stellate ganglion block, cervical epidural block, anterior scalene block and previous operation, including both carpal tunnel release, provided no remarkable relief to the patient. A left scalenectomy and first rib resection were performed by transaxillary approach and left cervical root neurolysis was done. After surgery, we measured CPT using neurometer and found conditions worsening in the opposite arm. We performed the same procedure on right side, and followed by CPT measurement. This case suggests that CPT is a useful measurement of recovery and progression of TOS.
