This study examines psycho-physiological effects of visual perception in super-high rise apartment exterior space. Theoretical research was used to explain the psycho-physiological effect of visual perception and case study was carried out to evaluate the physiological response of the subjects. For the physiological evaluation, six slides were chosen and the EEG was used. According to the results of the case study, the central nerve was activated by the slides with pleasant scenic views. In shows that the scenery composed of natural scenic elements effects psychological condition positively. Scenic views with natural scenery have a direct correlation with positive attitude. In conclusion, the results of this study show that the exterior space should contain natural scenic view to help users decrease their visual stress.

The purpose of this study was to investigate children's perception of reading. The researchers interviewed 120 children aged 5 to 7 (40 for each age group) by using a specially designed interview format. The study of Johns (1973) was referred to as a guide in preparing the format. Responses of the children were classified in accordance with criteria worked out on the basis of the researchers' previous studies and analyzed in terms of frequencies and percentiles by age group. ${\chi}^2$ test was used to analyze the data. The findings of the study were: (1) The younger the children, the higher the rate of showing no response or of responding only to concrete incidents or things. Older children in general showed higher responses relevant to reading comprehension than younger ones. (2) Older children were more inclined than younger ones to regard the process of reading as a skill-oriented, teacher-based process. (3) Children in these age groups showed little perception of reading's objectives of comprehension and communication.

Tall buildings are subjected to wind loading that can cause excessive wind-induced vibration. This vibration can affect the activities of the inhabitants of a building and in some cases fear for safety. Many codes and standards propose the use of curves of perception of acceleration that can be used to verify the serviceability limit state; however, these curves of perception do not take into account the uncertainty in wind-climate, structural properties, perception of motion and maximum response. The main objective of this study is to develop an empirical expression that includes these uncertainties in order to be incorporated into a simple procedure to evaluate the wind-induced acceleration in tall buildings. The use of the proposed procedure is described with a numerical example of a tall building located in Mexico.

We this study investiged the level of perception such as construction quality-related systems according to the subject of construction work. The results of the recognition moisture survey showed a high response rate in the order of construction companies and supervisors. The result of the system's level of understanding was low at 3.6 points for the orderer and contractor. In addition, in recognition of the effectiveness of the quality management system, the contractor showed a somewhat negative perception than other targets.

This study investigates how American English high back vowels are identified. American English and Korean speakers participated in a phonetic experiment for this study. This study shows their response times of the vowels and discusses how the speakers identified them. For the experiment I used a synthesized vowel continuum between American English /u/ and /$\mho$/based on American English male speakers' voice obtained by Peterson and Barney (1952). I manipulated spectral steps and vowel duration of the stimuli. The statistical results showed that American English speakers were not able to distinguish the stimuli based on spectral quality. Instead they relied on vowel duration. This suggests that the American English high back vowels have changed since Peterson and Barney recorded them in 1952. The Korean speakers also relied on vowel duration, not spectral quality since they could not distinguish them. American speakers' response times of these vowels were not affected by both spectral quality and vowel duration. Koreans' response times were affected by vowel durations only.

A lot of studies on the summary measures of predictive strength of categorical response models consider the likelihood ratio index (LRI), also known as the McFadden-R², a better option than many other measures. We propose a simple modification of the LRI that adjusts for the effect of the number of response categories on the measure and that also rescales its values, mimicking an underlying latent measure. The modified measure is applicable to both binary and ordinal response models fitted by maximum likelihood. Results from simulation studies and a real data example on the olfactory perception of boar taint show that the proposed measure outperforms most of the widely used goodness-of-fit measures for binary and ordinal models. The proposed R² interestingly proves quite invariant to an increasing number of response categories of an ordinal model.

This study, guided by Engeström's (1999, 2001) activity theory which owes its theoretical lineage to sociocultural theory, explores how roles (peer feedback givers and receivers) and tasks are distributed among EFL students who engage in peer response. More specifically, as an extension of previous research of focusing on "stances" ESL students adopt, I investigate whether different roles in peer response groups make a difference in the nature of peer response and identify what underlays the different roles in peer group interaction. In addition, I examine whether different roles to the peer response create tensions and contradictions in peer response and how these created conflicts lead to changes in peer response activity system. The data I wish to consider is first-person narratives elicited from two EFL college students. I use Won's and Choi's (both pseudonyms) stories as a heuristic, which is a method that allowing one to proceed fruitfully in finding information. Foregrounded in this study are the students' different roles in the same peer response activity. A division of labor exists between Won/Choi and their peers - the way tasks are divided up and the way roles are structured. Yet Won and Choi adopted rather divergent roles when participating in peer response activity and carried out qualitatively different peer response activities. It is obvious here that the distribution of their roles in carrying out this particular peer response is shaped by Won' and Choi's perception about the validity of their peers' responses.

본 연구는 대학생 집단이 미디어를 통해서 획득한 사이버범죄에 대한 위험인식을 확인하는 목적을 갖는다. 이를 위하여 대학생 집단에게 일반적인 위험인식, 과학적 지식, 자발성, 친숙성, 통제성, 재앙성, 두려움, 개인적 지식의 8문항으로 사이버범죄에 대한 위험인식을 확인하였다. 연구 결과, 실제로 대학생들이 느끼는 위험인식에서 인터넷 사기가 다른 유형에 비해 가장 낮은 위험인식을 나타냈는데 이는 대학생들이 사이버범죄에 대한 위험 정보를 획득하는 미디어 차이와 노출에서 기인함을 알 수 있었다. 사이버범죄에 대한 정보를 획득하는 미디어 종류에 따라서 대학생의 위험인식도 차이를 보였는데, 오락적 미디어보다는 뉴스 미디어에서 더욱 월등히 나타났다. 이는 우리사회에서 사이버범죄에 대한 정보를 전달하는 창구가 여전히 부족한 것을 알 수 있었다. 또한, 미디어의 이용 환경에 따라 각 개인별로 위험인식의 차이가 있다는 것과 사이버범죄의 영역에서도 미디어 노출에 따라 위험인식이 변화되고 있음을 확인할 수 있었다.

말초 신경 병변 환자들에게 하지 체성감각의 저하는 균형 능력 저하와 관련이 있다. 일반적으로 균형 능력은 운동 결과를 측정하여 평가하여 왔다. 그러나 인체 움직임은 다양한 감각 신호들이 통합된 운동지각에 의해 유발된다. 따라서, 본 연구에서는 하지 체성감각의 저하는 운동 지각 능력 또한 저하시킬 것이라는 가정하에, 이를 확인하기 위하여 허혈에 의한 하지 체성 감각 저하를 유도하였고, 이때의 피부감각 민감도 및 선형 운동 방향 지각 능력의 변화를 측정 하였다. 이 결과 발바닥 체성감각 저하 유도시에는 운동 지각 역시 저하되었다. 그러나 운동 결과에 해당하는 압력 중심은 변화하지 않았다. 따라서, 운동 지각 측정이 체성 감각 저하를 조기 발견할 수 있는 평가 방법으로 사용될 수 있음을 확인하였다.

The purpose of this study is that level of community members about dental hygienist's job of cognition and perception. The subjects of this survey were 500 of community members located in Gumi, Seoul, Incheon, Wonju.(response rate 92%) The results of study could be summarized as follows: 1. Women, 30 age group, officer and house keeper who had were experienced scaling higher level cognition of dental hygienist than another groups. 2. The group that had experienced oral examination, oral health consult, and the young group who had not experienced prosthodontic treatment had higher perception that dental hygienist main role is oral health care education. 3. The student who had experienced scaling had higher perception that dental hygienist's main role is oral disease prevention. 4. Over 30 age, women group who had experienced dental treatment between 6 month and 2 years had higher perception that dental hygienist main role is dental assistance At the conclusion of this investigation, We investigated that person's perception and cognition is promoted through scaling. Therefore we have to increase opportunity of oral health prevention and education role. In addition, we should notify dental hygienist with uniform, name tag and information about dental hygienist.
