  • This paper deals with the current phonological theory named the elementary theory Before manipulating this theory with highest depth, we need to discuss the distinctive feature theory which can be estimated as playing a central role in the standard generative trends. En the element-based phonological theory, the followings might act as tile main traits in differentiating it from other theories: the notion of phonological opposition is regarded as privative one, treating the univalent element as an analysing unit in a phonological process instead of distinctive features, and the nile convention in standard theory is replaced by the element. In chapter 2, a brief history of generative theory is to be described with respect to the merits and demerits of the distinctive feature theory. In chapter 3, After dealing with the current tendency and some prominent aspects of each element theory, a couple of problems thought to be confronted by the distinctive feature theory And the analysing method taken from the element-based theory which may be regarded currently as the alternative to the problems mentioned above will be discussed mainly, The government-based theory introduced by KLV(1985, 1988) may be the main target in discussing the current topic.

  • The shear strength of unsaturated soils, a research hotspot in geotechnical engineering, has great guiding significance for geotechnical engineering design. Although kinds of calculation models for the shear strength of unsaturated soil have been put forward by predecessors, there is still need for new models to extensively consider the nonlinear variation of shear strength, particularly for the nonlinear effect of the net normal stress on the shear strength of unsaturated soil. Here, the shear strength of unsaturated soils is explored to study the nonlinear effects of net normal stress with the introduction of a general nonlinear Mohr-Coulomb (M-C) strength criterion, and the relationship between the matric suction (or suction stress) and degree of saturation (DOS) constructed by the soil-water characteristics curve (SWCC) of van Genuchten is also applied for unsaturated soil. Then, two calculation models (i.e., an envelope shell model and an effective stress model) are established for the shear strength of unsaturated soils under the nonlinear strength theory. In these two models, the curve of the shear strength of unsaturated soils versus the net normal stress exhibits a tendency to gently. Moreover, the proposed formulas have flexibility and convenience with five parameters (for the effective stress model) or six parameters (for the envelope shell model), which are from the M-C strength parameters of the saturated soil and fitting parameters of SWCC of van Genuchten. Thereafter, by comparison with the classical theory of the shear strength of unsaturated soils from some actual cases, the rationality and accuracy of the present models were verified.

  • The goal-gradient hypothesis states that the tendency to approach a goal increases with the increasing proximity of the goal (Hull 1932). It was initially supported with an evidence of animal experiments and since then, several papers have investigated the goal-gradient hypothesis in humans. Although there are some evidences related to the goal-gradient hypothesis in human behaviors, none of previous studies can properly explain its underlying mechanism, and what's more, they were not able to suggest useful managerial applications in human behaviors. From these perspectives, this work points out that there are some theoretical weaknesses to apply the goal-gradient hypothesis into the complicated human decision-making behaviors and proposes an alternative theoretical mechanismthat underlies the goal-gradient hypothesis in human. Finally, it offers insights into managerial implications of the goal-gradient hypothesis in the marketing field. This study focuses on the changes in motivations for achieving goals, in terms of how approaches to goals vary according to temporal distance from those goals. Specifically, the temporal construal theory (Liberman and Trope 1998) is considered as the underlying mechanism of the goal-gradient in that the temporal construal theory argues how the temporal distance from a goal makes people change their associated values regarding to that goal. According to the temporal construal theory, the value of distant future outcomes (near future outcomes) is construed on the basis of abstract and central features (concrete and peripheral features), and it argues that distant future situations are construed on a higher level than near future situations. This means that the value associated with the high-level construal is enhanced over delay, whereas the value associated with the low-level construal is discounted over delay. Our propositions suggest that the goal-gradient behavior in human can be motivated by the different aspects or characteristics of the goal as time changes based on the temporal construal theory. Thus, the following propositions are proposed. P 1-1: If the goal is far away, consumers put more value on the central features that are more associated with the desirability of the goal. P 1-2: If the goal is far away, consumers put more effort into accomplishing the goal that has more central features, regardless of its peripheral features. P 2-1: If a goal is near, consumers put more value on the peripheral features that are more associated with the feasibility of the goal. P 2-2: If a goal is near, consumers put more effort into accomplishing the goal that has more peripheral features, regardless of its central features. We hope to provide sufficient managerial implications for the companies as our research aims to show how consumers react differently as they progress toward the goal. Proposed propositions may provide guidance for companies developing a loyalty program, enabling them to understand what kinds of benefits or services they should provide or emphasize to consumers in loyalty programs on the basis of the time-dependent changes in outcome values (such as gifts, reward coupons). The effects of temporal distance from a goal should inform companies' marketing activities and help themto determine where emphasis should be placed in designing the benefits of their loyalty program.

  • This study is concerned with the accuracy and the patterns when different methods was used in interpolation task. Although 3 methods employed the same modality for input (visual) and for output (manual responding), they differed in central processing, which method 1 is relatively more tendency of verbal processing, method 2 is realtively more tendency of spatial processing and method 3 needed a number of switching code (verbal/spatial) performing task. Split-plot design was adopted, which whole plot consisted of methods (3), orientations (horizon, vertical), base-line sizes (300, 500, 700 pixels) and split plot consisted of target locations (1-99). The results showed the anchor effect and the range effect. Method 2, method 3 and method 1 that order was better accuracy. ANOVA showed that the accuracy was significantly influenced by the method, the location of target, and its interactions ($method{\times}location$, $size{\times}location$). Analysis of error data, response time and frequency of under, just, over estimate indicated that a systematic error pattern was made in task and methods changed not only the performance but also the pattern. The results provided support for the importance of the multiple resources theory in accounting for S-C-R compatibility and task performance. They are discussed in terms of multiple resources theory and guidelines for system design is suggested by the S-C-R compatibility.

  • Purpose: This research was conducted to explore the experience of using Internet to solve health problems and to develope a grounded theory. Method: There were 15 subjects in their 30s who had experience using Internet to solve health problems for themselves and their families. Results: 114 concepts, 31 subcategories, and 9 categories were derived from the analysis by using approaches by Strauss & Corbin. Central phenomenon was "Primary healthcare information" and the core category was "Selecting ways to solve health problems". The participants' experiences were conceptualized into two perspectives: reliability of the information and tendency of preference among the sites. Conclusion: All of the processes found on Internet that solved health problems required the assistance of a health professional such as a nurse. It was judged that there are some differences in the degree of usage regarding health-related information, which was primarily in accordance with the confidence and attitude of the user with respect to Internet information. We presented a strategy that could operate with professionals and nonprofessionals. Therefore, we can be satisfied by the fact that this study suggests a complimentary nursing strategy to the healthcare on Internet.

  • This study set out to compare and analyze the influences Kabbalah, which was Louis I. Kahn's faith as a Jew, on his architecture based on Freud's psychoanalysis that had many exchanges with modernism and contemporary architecture and theories. The specific goals of the study were to shed light to Kahn's presence in contemporary architecture anew and establish the methodology of using psychoanalysis in building new theories of architectural planning. When the theories of psychoanalysis were introduced for comparison and analysis purposes, Kahn tried to differentiate his buildings by placing a function or symbolic central space at the heart of a building even though he did adopt a characteristic of modernism architecture, which was placing a core at the centre of plan, for a while. Such a tendency of his was based on Jung's opinions rather than Freud's and affected by Ecole des Beaux-Art. The analysis results also indicate that he conceived "Served Space & Servant Space," "architecture of connection" and "silence and light" that made up the essence of his architectural theory from the relationships between Ayin-Sof, Kabbalah's absolute god, and Sefiroth. It's also very likely that his often use of triangles and circles in his architecture was affected by the Tree of Sefiroth diagram of Kabbalah. His tendency is well reflected in Salk Institute and Philips Exeter Academy Library, where he placed a laboratory or courtyard at the center where a core was supposed to be, created a corridor or courtyard space between those central spaces and the core, and connected them one another with to perceive the being of Ayin-Sof into an architectural space, which is well proven with Mikveh Israel Synagogue where he directly applied the Tree of Sefiroth diagram. The synagogue also contained a hollow column that served as an important concept in his late architecture. The hollow column was also the result of him applying the concept of Sefiroth of the place where Ayin-Sof Was reduced in Kabbalah.

  • Hydrophobicity is the key concept to understand the role of water in protein folding, protein self-assembly, and protein-ligand interaction. Conventionally, hydrophobicity of amino acids in a protein has been argued based on hydrophobicity scales determined for individual free amino acids, assuming that those scales are unaltered when amino acids are embedded in a protein. Here, we investigate how the hydrophobicity of constituent amino acids depends on the protein context, in particular, on the total charge and secondary structures of a protein. To this end, we compute and analyze the hydration free energy - free energy change upon hydration quantifying the hydrophobicity - of three short proteins based on the integral-equation theory of liquids. We find that the hydration free energy of charged amino acids is significantly affected by the protein total charge and exhibits contrasting behavior depending on the protein net charge being positive or negative. We also observe that amino acids in the central ${\beta}$-strand sandwiched by ${\beta}$-sheets display more enhanced hydrophobicity than free amino acids, whereas those in the ${\alpha}$-helix do not clearly show such a tendency. Our results provide novel insights into the hydrophobicity of amino acids, and will be valuable for rationalizing and predicting the strength of water-mediated interaction involved in the biological activity of proteins.

  • 군 조직의 보안수준 변화요인을 확인하기 위해 시작된 본 연구는 현역 간부들이 군의 보안수준 향상을 바라며 국방일보에 투고한 기고문으로부터 수집된 데이터를 근거이론(Grounded Theory)이라는 질적연구 방법에 의해 분석 후 조직구성원들이 내부자 보안위협에 대해 어떻게 대응하는지에 관한 인과적 관계를 도출하였다. 분석 결과, 인과적 조건은 '내부자의 보안위협', 맥락적 조건은 '군 조직의 특수성', 중심현상은 '군인으로서 가치관의 충돌', 중재적 조건은 '보안의식', 전략은 '보안위협에 대응', 결과는 '보안수준 변화'로 나타났다. 핵심범주는 '내부자 보안위협에 대한 가치관의 충돌 정도'로 제시할 수 있으며, 두 가지의 가설이 도출되었다. 첫째, 군 조직의 구성원은 안보를 중시하는 성향이 강할수록 보안위협에 대한 가치관의 충돌을 강하게 느끼며 이에 강경하게 대응하여 조직의 보안수준을 발전시키는데 일조하고 있었다. 둘째, 동료를 중시하는 성향이 강할수록 보안위협에 대한 가치관의 충돌 정도가 약하며 이에 미온적으로 대응하여 조직의 보안수준을 퇴보시키고 있었다. 최종적으로 조직의 보안수준 향상을 위해서는 조직구성원들의 확고한 안보의식 확립을 위한 방안과 더불어 이를 뒷받침할 수 있는 제도적 발전이 필요함을 나타낸다.

  • There are few research on the social drinking experience reported by women. Thus, it is necessary to understand the increasing tendency of womens drinking experience in the sociocultural context. This study was aimed to explore and delineate the drinking experience of full-time house wives base don Strauss and Corbin's grounded theory (1998). The subjects of this study were 10 full-time middle-aged house wives who were living in Seoul region. The data were collected through several in-depth interviews and observations until the theoretical saturation was achieved. The data were analyzed using Strauss and Corbin's grounded theory method. The results of this study generated a paradigm that the drinking experience of the full-time middle-aged house wives has a core category of 'free-oneself-from' and is also connected with mingling, anguish, accessibility, reaction of other people, change, personal resources, self-expression and building relationships by drinking. All processes from the occurrence of the central phenomenon to extinction are as follows; 1) Starting the process of the drinking experience for mingling and resolving anguish, and by having an easy accessibility; 2) Perceiving the process of reaction by other people, physical change of herself. and psycho-behavioral change; 3) Experiencing the process of free-oneself from thorough drinking; 4) Acknowledging the process of the resources for free-oneself-from; 5) Selecting the process of self-expression according to the resources; 6) Building the process of the relationship with drinking as a way of self-expression. Based on this paradigm, 4 hypothesis and 4 types are generated. Thus, this study suggests that it is useful to develop nursing interventions to improve the self-esteem of the full-time middle-aged house wives and to provide them various methods of problem solving strategies. This study also proposes that there should be a strategic program for the women so that they could make a route for positive self-expression by achieving a proper relationship with drinking.
