The ratings of noise are consisted of physical factors and psychological factors. The physical factor means the scales and the spectrum characteristics of noise, on the other hand the psychological factor means the subjective emotion, sensation and individual judgement for it. Therefore the rating of noise must reflect the subjective psychology of people for it. But it is very difficult to establish an effective scale which can reflect well that because the subjective psychology has many variables according to the cultural differency, nationality and individual personalities. In this paper, Korean Vocabularys for the assessment of noise were surveyed in order to find out the effective noise scale for Korean.

The study proposes to draw out the correlation on what kinds of influences local government personnel's performance capability affect the overall quality of the project, and to suggest institutional supplement policies. For the study, two analytical methods are conducted. First, a hypothesis per each factor was set by classifying the factors which affect the personnel's performance capability into organizational and individual factors. Second, a survey was conducted targeting the project management personnels and presented the result on the verification of the hypothesis through statistic techniques. As the result, it is considered that the quality of forest tending project is more affected by the individual factors than the organizational factor, thereby this study suggests the methods of reinforcement in project management personnel's performance capability.

The study was to investigate the effect of the environmental factor on the emotion and satisfaction at the waiting lounge of the international cruise terminal. The results of the study were found as follows: first, the physical environmental factor of the lounge influenced on the positive emotion. Second, the social factor affected the positive emotion. Finally, emotion affected the positive satisfaction. This study suggested that environmental factor was totally affected by emotion and thus environmental management depended on an individual characteristics of the individual place. The port authority will need more efforts to make a better waiting lounge setting for higher tourist satisfaction.

Objectives Suicide is a complex phenomenon not only caused by the individual's mental illness and economic situation, but also occurred in sociocultural contexts and relationships around the individual. Therefore, the attitudes, which include collective norms, thoughts and feelings of a population, toward suicide play a fundamental role in the prevention of suicide. Factor structure of Attitudes Toward Suicide (ATTS), developed by Renberg, is also various in different sociocultural contexts. This is the first study to investigate factor structure of ATTS along with nationwide sample of Korean adults. Methods This study analyzed the factor structure and reliability of ATTS in 1500 regionally stratified Korean adults. Exploratory factor analysis was performed by using principal axis factoring and varimax rotation. Results The selection of 33 ATTS items based on internal consistency and communality was conducted. Five factors were analyzed, which were named 'Good reason,' 'Negative gaze,' 'Predictability,' 'Means of escape,' and 'Common secret,' respectively. Explained total variance was 41.94%, and the internal consistency ranged from 0.516 to 0.740. Conclusions Each of the five factors contains different semantic dimensions. Consistent with previous studies, factors containing permissive attitude toward suicide was high in those with history of suicidal thought and of suicide attempt. It is notable that the 'Good reason' showed higher score in elderly. This may be related to socioeconomic or physical adversities which have been considered the major cause of suicide in elderly.

The study was to investigate the effect of the environmental factor on the emotion and satisfaction at the waiting lounge of the Busan International Cruise Terminal. This study focus on tourist at the waiting area in the Busan International Cruise Terminal. The data was collected through self-administered questionnaires and the research performed to face-to-face interview. For data analysis, used SPSS 18.0 and AMOS 18.0 of a structural equation model. The results of the study were found as follows: first, the physical environmental factor of the lounge influenced on the positive emotion. Second, the social factor affected the positive emotion. Finally, emotion affected the positive satisfaction. This study suggested that environmental factor was totally affected by emotion and thus environmental management depended on an individual characteristics of the individual place. The port authority will need more efforts to make a better waiting lounge setting for higher tourist satisfaction.

It is known that an EEG is characterized by the unique and personal characteristics of an individual. Little research has been done to take into account these personal characteristics when analyzing EEG signals. Often the EEG has frequency components which can describe most of the significant characteristics. These combinations are often unique like individual human beings and yet they have an underlying basic characteristics as well. We think that these combinations are the personal characteristics frequency components of the EEG. In this seminar, the EEG analysis method by using the Genetic Algorithms (GA), Factor Analysis (FA), and the Neural Networks (NN) is proposed. The GA is used for selecting the personal characteristic frequency components. The FA is used for extracting the characteristics data of the EEG. The NN is used for estimating the characteristics data of the EEG. Finally, in order to show the effectiveness of the proposed method, classifying the EEG pattern is carried out via computer simulations. The EEG pattern is evaluated under 4 conditions: listening to Rock music, Schmaltzy Japanese ballad music, Healing music, and Classical music. The results, when personal characteristics frequency components are NOT used, gave over 80 % accuracy versus a 95 % accuracy when personal characteristics frequency components are used. This result of our experiment shows the effectiveness of the proposed method.

The purpose of this study was to establish the relative influences of individual variables (sex, age, temperament) and mother's psychosocial variables (maternal attitude, parenting stress, marriage satisfaction) on daily stress levels and maladjustment of young children attending at daycare centers. Subjects were 224 pairs of children and their mothers, and 18 teachers from 5 child-care centers in Gwangju City. Children were tested individually using 22-item daily stress inventory with illustrations which described certain stressful situations. Questionnaires were also administered to mothers and teachers. Collected data were subjected to Cronbach's $\alpha$, correlation and multiple regression analysis using SPSS (WIN 14.0) program. The major findings were as follows; Overall average score of children's daily stress was equivalent with the median. 'Blame and attack situation' and 'anxiety and frustrated situation' were perceived as more stressful for children than 'lose self-respect situation'. Overall average score of children's maladjustment was lower than the median. 'Overactivity' was highest among subscores of maladjustment. Age was the only significant influential factor on children's daily stress level. Sex was the most influential factor on 'overactivity', 'aggression', and 'regression' of young children. Activity and maternal stress were the second most influential factor on 'overactivity' and 'aggression', respectively.

In a single-phase power factor correction (PFC), the standard cascaded control algorithm using a proportional-integral-derivative (PID) controller has two main drawbacks: an inability to track sinusoidal current reference and low harmonic compensation capability. These drawbacks cause poor power factor and high harmonics in grid current. To improve these drawbacks, this paper uses a proportional-integral-derivative-resonant (PIDR) controller which combines a type-III PID with proportional-resonant (PR) controllers in the PFC. Based on a small signal model of the PFC, the type-III PID controller was implemented taking into account the bandwidth and phase margin of the PFC system. To adopt the PR controllers, the spectrum of inductor current of the PFC was analyzed in frequency domain. The hybrid PIDR controller were simulated using PSCAD/EMTDC and implemented on a 3 kW PFC prototype hardware. The performance results of the hybrid PIDR controller were compared with those of an individual type-III PID controller. Both controllers were implemented successfully in the single-phase PFC. The total harmonic distortion of the proposed controller were much better than those of the individual type-III PID controller.
