  • The purpose of this study is to investigate the impact of members' perception of unit change management efforts on their emotional-organizational commitment during the military restructuring. The mediating effect of change acceptance of the members in this relationship is also studied. Currently, the military is seeking to restructure its military construct in order to actively cope with the rapidly changing security situation and the decrease in military service resources. If an organization fails to effectively manage its changes when undergoing restructuring, it is difficult to expect the success of organizational change due to its members' resistance to change. Therefore, this study suggested the effect of members' perception of personnel fairness and transformational leadership on their emotional-organizational commitment and the mediating role of the members' change acceptance in the relationship between them as the hypotheses. Survey results show that personnel justice and transformational leadership has a positive impact on the emotional-organizational commitment of the members, and that the change acceptance of the members partially mediates the relationship between them. By presenting the mediating effect of change acceptance with theoretical implications, the theory has been expanded. In practice, the change management activities for the restructuring of the military structure have been identified, and the effort for enhancing the change acceptance of the members is required to success on the organizational restructuring.

  • Recently, as earthquake is more frequently taking place around the world due to diastrophism, the importance of diastrophism and disaster detection is becoming more important. In this study, to analyze the interpretation of seismic displacement by the Japanese earthquake in March, 2011, and monitor the diastrophism of plates in Japan and surrounding Eurasia, Pacific, and Philippines before and after the earthquake, the observational data from IGS observatories in Japan and Asian regions were processed by precise point positioning. The displacement was biggest in MIZU, which was the closest to the epicenter, and the earthquake-affected region was in inverse proportion to the distance from the epicenter. The result of calculating the diastrophism speed before and after the earthquake, based on precise point positioning of IGS observatories located in the 4 plates around Japan, showed that the displacement speed changed and different plates showed different results. The comparison with the plate fate model allowed to analyze the change in diastrophism by earthquake, and to understand the characteristics of the displacement of the plates around Japan. Later, a continuous diastrophism monitoring based on GPS is needed for earthquake prediction and diastrophism research, and the data gained by continuous GPS-based monitoring of diastrophism will be fully used as basic data for relevant research and earthquake disaster management.

  • The lower limb somatosensory deficit observed among peripheral neuropathy patients is partially related to the decline in their balance ability. In general, balance ability has been examined by measuring the postural response (i.e., action). However, body motion is induced by integrated multisensory cues (i.e., motion perception). In this study, we hypothesized that the reduced lower limb somatosensation might also lower motion perception. We induced lower limb sensory deficits through ischemia and then measured the cutaneous sensory sensitivity and directional motion perception. The sensory deficit was successfully induced, and it also lowered the motion perception. However, the center of pressure (COP) variation did not significantly change under the sensory deficit. This result implies that measuring motion perception could enable the detection of precursors of sensory deficits.

  • Nowadays, some movie theaters provide additional sensory information in 3D movies to enhance visually induced motion perception. However, no studies have investigated how motion perception increases. Thus, in this study, we examined the effect of visual coherent sensory information on visually induced motion perception and quantification of sensory information. A visual stimulus rotated sinusoidally and visual coherent sensory information were applied as vibrations to a subject's foot. We measured the sway of the subject's body by using a force plate and somatosensory bar rotation that represents the subject's perception of the horizon using an encoder. By using this data, we obtained the weight of the sensory information using a Kalman filter. As a result, it was found that subjects rotated the somatosensory bar more when visual coherent vibrations were applied. The weight of vision also increased when visual coherent vibrations were applied. Thus, we can conclude that visual coherent sensory information tends to enhance visually induced motion perception and weight of vision.

  • The relationships between the ability to understand changes in meaning depending on the prosody of spoken words and the ability to perceive pitch and melodic contour in cochlear implants (CI) recipients were examined. Fifteen postlingual CI recipients were measured in terms of speech prosody perception, speech perception, pitch discrimination (PD), and melody contour identification (MCI). The speech prosody perception test consists of words with positive (PW) and neutral meaning (NW). Participants were asked to identify the meaning of words depending on the conditions of positive and negative prosody. The MCI consists of subtests 1 and 2 with different chance levels to choose. Then, the relationships between speech prosody perception, speech perception, PD, and MCI performance were analyzed. There was a significant difference in identifying the meaning of words expressed in a different prosody between the PW and NW conditions. Speech prosody perception showed a significant correlation with MCI 1 while there was no significant relationship with speech perception. Although speech perception may be possible after CI, limited spoken word comprehension due to decreased sensitivity for prosodic changes may persist in CI recipients. In addition, there was a limitation in perception of melodic contour change compared to pitch discrimination, which is related to speech prosody perception.

  • 본 연구는 한국어를 학습한 경험이 없는 일본인의 한국어 치경폐쇄음 세 음소 범주(/ㄷ/, /ㄸ/, /ㅌ/)에 대한 지각 학습이 양순폐쇄음 세 음소(/ㅂ/. /ㅃ/, /ㅍ/) 지각에 미치는 효과를 검토하였다. 김윤현과 김정오 (2005)는 일본인들이 지각 학습과제에서 한국어 치경폐쇄음 세 범주를 구분할 때 기식성. 긴장성과 같은 변별 자질에 선택주의 하게 됨을 시사하는 결과를 얻었다. 치경음에 대한 지각 학습으로 적절한 단서에 선택주의 하게 되었다면, 같은 지각 차원에 따라 세 범주로 구분되는 양순음의 경우에도 치경폐쇄음 학습 후 음성자극들을 옳게 범주화를 할 것이다. 실험 결과, 치경폐쇄음 자극(/다/, /따/, /타/)만으로 이루어진 동일-상이판단 학습 과제에서 치경폐쇄음 파악의 정확율은 29.1%(표준오차=3.02) 증가하였고, 조음 위치의 변화에 따른 음향적 차이에도 불구하고 양순폐쇄음의 정반응율도 15.8%(표준오차=3.27)의 향상을 보였다. 이 전이효과는 치경음 지각 학습 때문에 일본인들이 폐쇄음의 세 음소 범주를 구분하는 적절한 지각 차원에 선택주의하게 되었음을 시사한다.

  • The perceived position of a flashing target object is generally biased towards the direction of eye movement when there is no reference around the target. Current research examined the localization accuracy of a flashing target relative to a static reference. The perceived location of the target relative to the reference was distorted and the pattern of perceptual distortion systematically depended on the position of the reference relative to the target. This kind of result was consistently observed regardless of the distance between the reference and the target and direction of pursuit eye movement. We have discussed how these results could he explained by the theories previously suggested to explain the localization of objects.

  • Monitoring of crustal movement by earthquake is an important line of study in geophysics and geodesy. In this Study, before and after the earthquake data about nine IGS permanent stations were processed by Precise Positioning System to analysis the influence area about Japanese earthquake in March 11 at 2:46pm. As the result of crustal deformation monitoring, the quantitative earthquake displacement and change of crustal movement was presented. Crustal movement monitoring using continuous GPS data processing is necessary for crustal research and predicting earthquake because crustal movement assumed a new aspect before and after the earthquake in Japan.

  • 본 연구는 가족의 구매의사결정에 대한 실증조사로서 성별역할관념론 및 자원이론과 가족구성원의 지각된 영향 간의 관계를 규명하였다. 영향을 주는 구성원은 남편과 아내와 자녀로 한정했으며, 영향을 지각하는 가족구성원은 남편과 아내로 제한하였다. 성별역할관념변수는 Scanzoni Sex-Role Scale(SSRS)로 측정하였으며, 자원변수는 남편과 아내 각자의 수입과 교육수준으로 측정하였다. SSRS 는 요인분석을 사용하여 차원(요인)을 파악한 후 자원변수와 함께 지각된 영향 간의 관계를 규명하기 위하여 다변량 회귀분석을 사용하였다. 요인분석 결과는 Scanzoni(1975)의 분석 결과와 요인구조 면에서 차이가 있었다. SSRS 는 아내의 척도 2 개 차원과 남편의 척도 3 개 차원으로 구성되어 있다. 그러나 본 연구에서 남편의 척도는 1 개의 차원으로 나타났다. 조사대상이 된 제품은 TV, 냉장고, 세탁기, 침대, 장롱, 식탁, 자동차, 남성정장, 여성정장, 여행지로 모두 10 개 였다. 성별역할관념변수의 영향을 분석한 결과는 "제품 특이적"이거나, 영향을 지각하는 "지각주체 특이적"이거나, 성별역할관념의 "차원 특이적" 현상을 보였다. 또한 우리나라의 남편들은 성별역할관념변수에 상관없이 자기의 영향을 더욱더 크게 지각하는 반면, 아내의 영향을 더욱더 적게 지각하는 경향이 있었다. 아내들도 남편보다는 자기의 영향을 더욱더 크게 지각하는 경향이 있으나 남편만큼 강한 것은 아니었다. 이 결과를 분석하면 남편들은 남성우월의 전통을 유지하려는 경향이 높은 반면 아내들은 이런 전통에 변화를 기대하는 진보적 성향을 띠고 있는 것으로 해석된다. 본 연구의 결과 자원이론은 지지를 받지 못하는 것으로 나타났다. 다시 말해 자원이론은 부부사이에서 기대했던 영향과 반대 방향으로 나타났을 뿐만 아니라 부모와 자식 간에도 기대했던 것과 반대 방향으로 나타났다.

  • To adapt to the constant change in the foodservice industry, dietary life is not only evolving variously and complicatedly, but eating-out styles are also changing fast. In this reality, this study is intended to examine the effects of marketing mix strategies on perceived value and loyalty in Korean restaurants. To achieve this, a survey was carried out to total 300 customers of Korean restaurants in Seoul from June 11 to June 30, 2013. The results were as follows. First, service experience, price and store image in Korean restaurants had a positive effect on the perceived value. Second, price, advertisement and store image in Korean restaurants had a positive effect on the loyalty. Third, the perceived value had a significant positive effect on the loyalty. As stated above, service experience, price and store image, and price, advertisement and store image in Korean restaurants had an effect on the perceived value and the loyalty, respectively. Also, the perceived value had an effect on the loyalty. Consequently, these factors are very useful as marketing mix strategies in Korean restaurants.
