Evaluation is to be seen a~ a central component of design activity. It is an attempt to ensure that the proposal which arises is accepted and that the resulting artefact itself suited to its purposes in practice. Recent surveys of Evaluation show that most methods require quantitative and explicit attributes. Always a significant part of the attributes of design proposals is qualitative. Therefore we need some study that convert qualitative attributes into quantitative scale values, because in many cases con\ulcornerclusions can be drawn about the order of the overall value of the design proposals. Following to Thurstone's psychological scaling methods, attributive values are assigned by ruting scale methods, met, hod of rank-order and method of paired comparisons. The problem of psycho\ulcornerlogical scaling is then to determine whether the stimuli can be ordered on a psychological continuum with respect to the degree of the attributes each possesses. The law of comparative judgement assumes that for a given stimulus there is associated a most frequently aroused or modal discriminal process on a psychological continuum. This paper is based upon the premise that the modal discriminul process will also be the same as the mean or median of the distribution.The objective of this paper is to argue for an acceptance of qualitative approaches to the evalua\ulcornertion of Design as a complement to the existing quantitative techniques. The scale values of 10 attri\ulcornerbutes \ulcorner(1) originality, (2) aesthetics, (3) satisfaction, (4) effeciency, (5) function, (6) size, (7) texture, (8) simplicity, (9) symbol, and (10) facility) in case of TV sets are obtained and their interactions are examined.

In case a middle school music room locating in Iksan City, this space had been finished its construction work with the indiscreet sound-absorbing materials despite the music lesson is taught thereat. Accordingly, when music lesson since it sounds aridly due to insufficiency of echo and sound-volume feeling in music appreciation or music performance sound, there is some difficulty in the music lesson. For the purpose to control the obstructive factors owing to such short Reverberation Time, it optimizes the acoustic factor using Acoustic Simulation after arrangement of Acoustic Design, it has conducted a Psycho-acoustics Experiment using the Auralizational Technique that can experience the Virtual Acoustic Field at its designing stage. As the result of investigation about the acoustic satisfaction on the relevant subject space and the satisfaction with regard to the pertinent each items, it was known that the valuation on acoustic performance was evidently improved at 'after-reformation' than 'before-reformation'. It is considered that such material could be utilized as the useful material that can improve the architectural acoustic factor when construction and renovation of any middle school music room in the future.

잡음은 음성과 관련된 시스템의 성능을 제한하는 주된 원인이기 때문에 음성향상과 관련된 연구는 꾸준히 계속되어왔다. 전통적인 음성향상 방법은 무성음과 잡음을 구분하지 알기 때문에 잡음제거 과정에서 무성음이 함께 제거되는 단점이 있으며, 웨이블릿 기반의 전통적인 잡음제거 방법은 각 대역마다 동일한 문턱값을 사용하기 때문에 시변 환경에서 성능이 떨어지는 단점이 있다. 이 단점들을 개선하기위해 다중대역 파워 차감법과 Perceptual 웨이블릿 패킷 분해를 이용한 웨이블릿 기반의 개선된 음성향상 방법을 제안한다. 전처리 과정으로 다중대역 파워 차감법을 사용하여 광대역 잡음을 제거하고 뮤지컬 잡음의 발생을 줄이며, psycho-acoustic 모델 기반 Perceptual 웨이블릿 패킷으로 신호를 분해한 후 각 웨이블릿 노드의 엔트로피 비율과 음성검출을 이용하여 무성음/유성음/잡음을 구분한다. 구분된 신호에 따라 각 웨이블릿 노드마다의 문턱값을 기준으로 웨이블릿 Shrinkage를 적용하여 잡음을 제거하고 무성음이나 파워가 작은 유성음이 제거되는 오류를 최소화한다. 또한 잡음 파워 추정 과정에 적응적으로 망각 계수를 선택하여 잡음 파워 추정 오류를 최소화한다.

Sickness absence is one of the most important indicators for worker's health and occupational safety and health performance. Sickness absence is primarily depended upon sickness but psycho-social factors in workplace may moderate sickness absence. Even though worker is falling into illness, sickness absence can be prevented by job satisfaction. In Korea it is very difficult to find research output about the association of sickness absence with job satisfaction. This study is planned to investigate the effect of job satisfaction on sickness absence. The third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011 was used to analyze by logistic regression analysis. The result has shown that job satisfaction has statistically significant effect on sickness absence and simultaneously diminish the effect of symptoms experience on sickness absence. The effect of job satisfaction is greater in short term sickness absence than in long term sickness absence. This study has some limitation because of the cross sectional data of Korean Working Conditions Survey. In future, sophisticated statistical analysis may be done with modelling.

This study intends to define $\ulcorner$personality$\lrcorner$ as $\ulcorner$Human-ware$\lrcorner$ based on $\ulcorner$Gene-ware$\lrcorner$ in business management. The sides of personality in management are important source of manifestation of ‘Synergy’, because the importance of personality, that is, $\ulcorner$attitude$\lrcorner$ in individuals is increasing compared with the traditional techniques, $\ulcorner$craft$\lrcorner$. In this work it is considered that Human-ware activates interchange in reciprocal relation between Gene-ware and Hard-ware and performs balancing, intermediating (catalyzing) functions in relative that things(Geneware $\leftrightarrow$ Humanware $\leftrightarrow$ Hardware). $\ulcorner$Gene-ware$\lrcorner$ represents factor and phenomena of life in evolutionary information as human instincts, system of Gene-duum(Gene＋Residuum(in phenomenology) ), Synchronization(in structuralism). In this view, this paper defines the concepts and effects of personality in management as the results of creative and stational functions of Human-ware. And this paper intends to identify the strata of psycho in human as three vertical aspects of $\ulcorner$Manifest$\lrcorner$, $\ulcorner$Latent$\lrcorner$, and $\ulcorner$Found$\lrcorner$, in this respects, function of Human-ware have analogy to that of Manifest in psychological behaviors. Finally, reviewing the Ford system based on Fordism and Taylor's system in Industrial Engineering, pursues the meaning and importance of personality, that is Humanware in management.

It is said that the goal of the design of good acoustical environment is at first the reduction of undesirable sounds, and in addition the introduction of desirable sounds by which our minds are soothed. The task of creating the desirable sounds leads to the realization of a comfortable acoustic environment and the design of soundscape. It may be an important starting point of soundscape design to select suitable sounds for the target spaces, because each space has a different surrounding condition and requires a special ambient sound. This paper aims to survey preference of the environmental sounds suitable for the public spaces in urban areas such as parks, bus terminals. 35 kinds of natural sounds are rated by 26 pairs of adjectives. The results of psycho-acoustic experiments are as follows. 1. The proper adjectives for expressing the environmental sounds are classified into 6 groups of comfort, pleasure, fullness, variety, distinctness, naturalness. 2. Bird singing, murmuring of a stream, artificial sounds, singing of insects and animals are the affirmative order of preference. 3. Green musics consisted of music and natural sounds are preferred to the pure natural sounds. 4. Sound level relative to background noise causes various preferences to natural sounds in public spaces.

MPEG Surround is an audio coding technology that represents multi-channel audio signal with downmixed audio signal(s) and very low bitrate side information based on Binaural Cue Coding. The side information consists of Inter-Channel Level Difference, Inter-Channel Correlation, and payloads. These two parameters are correspondent to the well-known spatial parameters in psycho-acoustics, Inter-aural Level Difference (ILD) and Inter-Aural Cross Correlation (IACC). Though ICLD is to provide perceptually equivalent ILD to the listener, however, the ILD of the original multi-channel audio signal and that of the MPEG Surround encoded signal was different. The difference between two ILD values is defined as ILD Distortion (ILDD). This paper provides how ILDD can be applied to enhance sound quality in MPEG Surround and how much ILDD is decreased.

Purpose: The purpose of this study was to analyze the characteristics and effects of the forest therapy programs for adult patients. Methods: Six databases (PubMed, Cochrane library, CiNii, PsychoInFO, AGRICOL, EMBASE) and six domestic databases were systematically searched with language restrictions of Korean, English, and Japanese. The systematic review was based on the Preferred Reporting Items Systematic Reviews and Meta-Analysis (PRISMA) flow diagram. Results: Twenty five studies met the inclusion criteria. A systematic review identified adult patients classified as 1) disease of the circulatory system, 2) mental and behavioral disorders, 3) malignant neoplasms, 4) etc. (diabetes mellitus, chronic pain). This integrative review showed a positive effect of the forest therapy program for adult patients on physiological indices such as blood pressure, heart rate, heart rate variability, level of stress hormone, and natural killer cells as well as social·psychological indices such as the Profile of Mood States (POMS), anxiety, depression, and quality of life. Conclusion: The results of this study could be useful key principles in developing and applying the forest therapy programs in nursing intervention. Further research should be conducted to develop the forest therapy programs suitable for each patient group and measure its effectiveness.

Die vorligende Arbeit behandelt die Probleme der $Koh\"{a}renz$ und Interpretation von van de Velde unter einigen Gesichtspunkten, welche mit der Frage $zusammenh\"{a}ngen$: Wie wird Sprachverstehen $erm\"{o}glicht$? Nach van de Velde besteht der wissen­schaftliche Zugang zu den Sprachverstehensprozessen und Interpretationsstrategien darin, dass man Erkenntnisse $\"{u}ber$ ihre bedingenden Faktoren gewinnt Seine Arbeit versucht diese bedingenden Faktoren in folgenden Gegebenheiten aufzufinden: 1) in den innersprachlichen Gegebenheiten, 2) in den $Referenzzusammenh\"{a}ngen$, auf die sich innersprachliche Gegebenheiten beziehen, 3) in den Handlungskontexten, in denen die verwendeten Sprachgegebenheiten ihre Funktionen haben, 4) in den zwischenmenschlichen $Kormnunikationsrahmenverh\"{a}lnissen$, 5) in den kognitiven Prozessen des Sprachrezipienten, in der neuro(psycho)logischen Ausstattung des Sprachbenutzers. Genau gesagt, bleiben die folgenden Fragen trotzdem immer nur offen: 1) Kann jede Ebene $f\"{u}r$ die $Koh\"{a}renz$ bei van de Velde in der Wirklichkeit schon da sein? 2) Sind die Wertigkeiten jeder Ebenen gleich? 3) Muss die $Koh\"{a}renz$ zwischen Inferenz und Verstehen sein? 4) Gibt es irgendeine Einheitstheorie, solche $interdisziplin\"{a}re$ Faktoren zu beherrschen?

Purpose: This study was conducted to investigate the individual and cross influences of age, gender, and severity on recovery of patients with brain injury. Methods: For the purpose of the study, traumatic or spontaneous brain injury patients admitted to the intensive care unit (ICU) were conveniently selected. The data regarding outcomes were collected 3 months after admission. Results: Individual influences of the study variables on patients' recovery were significant, except for gender. But while the individual influence of gender on recovery was not significant, cross influence of gender and age was significant, but only for the sub-dimension of 'arousalbility and awareness'. The study results also showed that 3-way cross influence of gender, age, and severity was only significant on the sub-dimension of 'arousalbility and awareness'. Conclusion: The sub-dimension of recovery cross influenced by the demographic factors of gender and age, and severity was 'arousalbility and awareness'. This might indicate that the study variables that cross influencing recovery had more influence on consciousness compared to physical function and psycho-social adaptation.
