The traditional roles of leaders are to influence members and motivate them to achieve shared goals in organizations. However, leaders such as top managers and chief executive officers, in practice, do not always directly meet or influence other company members. In fact, they tend to have the greatest impact on their members through formal speeches, company procedures, and the like. As such, official speech is directly related to the motivation of company employees. In an official speech, not only the contents of the speech, but also the voice characteristics of the speaker have an important influence on listeners, as the different vocal characteristics of a person can have different effects on the listener. Therefore, according to the voice characteristics of a leader, the cognition of the members may change, and, the degree to which the members are influenced and motivated will be different. This study identifies how members may perceive a speech differently according to the different voice characteristics of leaders in formal speeches. Further, different perceptions about voices will influence members' cognition of the leader, for example, in how trustworthy they appear. The study analyzed recorded speeches of leaders, and extracted features of their speaking style through digital speech signal analysis. Then, parameters were extracted and analyzed by the time domain, frequency domain, and spectrogram domain methods. We also analyzed the parameters for use in Natural Language Processing. We investigated which leader's voice characteristics had more influence on members or were more effective on them. A person's voice characteristics can be changed. Therefore, leaders who seek to influence members in formal speeches should have effective voice characteristics to motivate followers.

본 연구에서는 국내 상장 제조기업을 대상으로 경영성과에 대해 경영자 보상이 하방경직적으로 반응하는지를 분석하고, 이런 경영성과에 대한 하방경직적 보상민감도가 기업 내 경영자의 역할비중에 따라 어떻게 달라지는지를 분석하는데 있다. 2006년부터 2009년까지 250개 상장제조기업, 1,000개 기업-연도 자료를 바탕으로 이상에서 제시한 연구목적을 실증분석한 결과를 요약하면 다음과 같다. 첫째, 우리나라 상장제조기업의 경우 경영성과(ROA)에 증감에 대해 경영자 보상이 하방경직적으로 반응하는 것으로 나타났다. 구체적으로 경영성과의 증가에 대해 경영자 보상의 증가보다, 경영성과의 감소에 대한 경영자 보상의 감소폭이 작은 것으로 나타났다. 둘째, 기업 내 경영자 역할비중에 따라 경영성과에 대한 경영자 보상의 하방경직적 민감도가 존재하는지를 분석한 결과 이들 요인들이 경영자 보상의 하방경직성에 보다 큰 영향을 미치는 것으로 나타났다. 구체적으로 기업 내 경영자 역할비중 및 영향력이 보다 클 것으로 기대되는 기업특성으로 투자기회집합의 크기, 무형자산 가치, 경영환경의 불확실성, 기업규모, 조직구조의 복잡성을 고려하였는데, 기업규모를 제외한 나머지 특성들을 가지는 기업에서 경영자 보상의 하방경직성이 더욱 커지는 것으로 나타났다. 그러나 기업규모의 경우 기대와 달리 하방경직성이 완화되는 것으로 나타났는데, 이는 기업규모가 큰 기업의 경우 경영성과와 연계된 경영자 보상제도가 더욱 잘 구축되어 있기 때문일 것으로 판단된다. 이상의 연구결과는 경영자 보상이 성과의 증감에 따라 차별적으로 반응한다는 기존의 선행연구의 결과를 확인한 것이고, 나아가 이런 비대칭적 성과-보상 민감도가 왜 발생하는지에 대한 이유를 기업 내 경영자의 역할비중 및 영향력에서 찾아 보았다는데 연구의 의의를 찾을 수 있다.

The influence of simple electrolyte or anionic trashes on cationic starch adsorption was examined using deinked pulp and bleached thermomechniical pulp. Adsorbed amounts of cationic starches increased slightly , then decreased abruptly as the concentration of simple electrolyte increased. This phenomenon was discussed based on the compression of electrical double layer and conformation change of starch molecules. Also, the effect of the type of simple electrolytes on starch adsorption was examined and discussed. Addition of sodium slilicate increased starch adsorption since it increased surface charge density of fibers. On the other hand, addition of kraft lignin decreased cationic demand of the pulp slurries and adsorbed amounts of cationic starches. Nonionic surfactant did not show any significant effect on the cationic demand of pulp slurries. When simple electrolytes were added to the stock , grater adsorption or cationic starches was obtained with starches of lower degree of substitution . On t도 other hand, amount of adsorbed starches decreased for lower DS starches when the concentration of anionic trashes increased.

The use of AFO in the management of patients with hemiplegia has been somewhat controversial. The purpose of the study was to identify the influence of the plastic ankle foot orthoses(AFO) on the characteristics of pelvic tilt in the patients with hemiplegia. Sixteen hemiplegic patients participated. The angle of pelvic tilt were measured using the BROM II . Results showed that the hemiplegia who weared plastic AFO, the angle of pelvic tilt was significantly less than not weared subjects. However. duration of wearing a plastic AFO and the degree of spasticity were not affected to the angle of pelvic tilt. Therefore the patients with hemiplegia should consider using the brace for the right purpose, also need to maintain the mobility of ankle joint while wearing the plastic AFO.

This study explores the major factors that are likely to affect the acceptance and resistance of innovative products and services. The TAM (Technology Acceptance Model) has been widely used for understanding consumer acceptance of new technology. This model displays perceived usefulness and perceived ease of use as antecedents of intention to adopt and use. However, research has reported a variety of preceding variables for technology acceptance. In addition, considering paradoxes of technology, research regarding both acceptance and resistance in an integrated model can explain consumer perception and behavior in detail. The results of this study states that relative benefits, degree of innovation in technology, perceived usefulness and perceived ease of use have had positive influence on the intention to adopt but negative impact on that of resistance. However, alterations of usage and perceived risk positively affects resistance, but also have negative effects on the intention to adopt. Finally, intention to adopt has comparatively greater influence than that of resistance on intention to use. Theoretical and managerial implications of the results are also discussed.

To modularize the joints of Hanok, the bending strengths of butterfly joints between pre-cut and manual member were compared. Structural size joints were manufactured and the length, width and thickness of each tenon were produced with different sizes. The ultimate load of pre-cut members was 2 times higher than that of manual members. Degree of anchorage for the joints on pre-cut member was also superior to that of manual member. By the F-test results, a great influence between ultimate load and sizes of tenon was found. In result of multiple regression analysis, the length and thickness of tenon were showed proportion relationships with the ultimate load, but the width of tenon was showed inverse proportion with the ultimate load. The results of this study can be used to identify the relationships among the major influence factors. Futhermore, it might be used as basic data for modularization the joints of Hanok.

This study investigated the perception of emotional voices by transplanting some or all of the prosodic aspects, i.e. pitch, duration, and intensity, of the utterances produced with emotional voices onto those with normal voices and vice versa. Listening evaluation by 24 raters revealed that prosodic effect was greater than segmental & vocal quality effect on the preception of the emotion. The degree of influence of prosody and that of segments & vocal quality varied according to the type of emotion. As for fear, prosodic elements had far greater influence than segmental & vocal quality elements whereas segmental and vocal elements had as much effect as prosody on the perception of happy voices. Different amount of contribution to the perception of emotion was found among prosodic features with the descending order of pitch, duration and intensity. As for the length of the utterances, the perception of emotion was more effective with long utterances than with short utterances.

Various controllable parameters of an experiment have influence on grinding process. In order to get good products with a high quality, these parameters should be considered whether each parameter has relations to the quality. This paper describes the use of the design of experiments to minimize geometric error in surface grinding. Controllable parameters for the design of experiments were selected as spindle speed, table speed, depth of cut and grain size. From the experimental results, a degree of influence between these parameters and the geometric error was evaluated. An optimal set of grinding conditions was obtained by means of analysis of variance(ANOVA).
