Purpose: The ultimate purpose of this work is to investigate gender differences in the relationships between product quality cues and perceived values at a food select shop. Specifically, this study examines the effects of internal and external cues, which are indicators of product quality, on emotional and social values based on gender differences. Research design, data and methodology: In this study, a questionnaire technique was used to collect the data necessary to test the proposed model. 183 data were collected through this technique. PLS SEM (Partial Least Squares Structured Equation Model) was used to test the research model. Results: First, there is no gender difference between intrinsic cue and emotional value. When using male and female data, there was no significant causal relationship between intrinsic cues and emotional values. Second, we found no gender difference between intrinsic cue and social value. When analyzed with female data, there was no significant causal relationship between intrinsic cue and social value. On the other hand, in the case of men, it was found that a weak causal relationship exists. Third, this study found gender difference between extrinsic cue and emotional value. In the case of men, it was found that a weak causal relationship exists, whereas in the case of women, a strong causal relationship exists between extrinsic cue and emotional value. Fourth, we found gender difference between extrinsic cue and social value. In the case of men, there was no causal relationship, whereas in the case of women, there was a strong causal relationship between extrinsic cue and social value. Finally, we found that there are moderating roles of gender in the relationship between external cues and perceived quality. Conclusions: As a result of analysis, it is necessary to focus on extrinsic clues of product in order to increase the perceived emotional and social values of women. On the other hand, in order to improve the perceived emotional and social values of men, it is necessary to pay attention to both intrinsic and extrinsic cues of product. Therefore, it is necessary to consider what clues and values are important to core customers.

The purpose of this study is to examine the relationship between utilization of technology and TPACK in mathematics teachers, and to analyze needs and retentions, difference between needs and retentions, and educational needs of TPACK in mathematics teachers. Furthermore, we will prioritize TPACK items that mathematics teachers want to change, and provide implications for teacher education related to TPACK in the future. To do this, we analyzed 328 mathematics teachers nationwide by using survey on the utilization of technology, averages of TPACK's needs and retentions, t-test of two averages, Borich's educational needs analysis, and the Locus for Focus model. The results are as follows. Firstly, the actual utilization rate was lower than the positive recognition of utilization of technology by mathematics teachers, and many mathematics teachers mentioned the lack of knowledge related to TPACK. Secondly, the characteristics of in-service mathematics teacher's needs and retentions for TPACK were clear, and TPACK's starting line of in-service mathematics teacher can be different from pre-mathematics teacher's. The retentions was high in the order of CK, PCK and PK, and the needs was higher in the order of TPACK, TCK, TK and TPK. All of the higher retentions were knowledge related to PCK, and the value of CK was extremely high among them. In addition, mathematics teachers recognized needs for integrated knowledge related to technology, and they needed more TCK than TPK. The difference between needs and retentions showed that all items except two items in the PK were significant. Retentions of all items in CK was higher than needs, needs of all items in TK, TCK, TPK and TPACK was higher than retentions, PK and PCK were mixed. Thirdly, based on the analysis of Borich's educational needs and the Locus for Focus model, teacher education on TPACK for mathematics teachers needs to focus on TPACK, TK, TCK, and TPK. Specifically, TPACK needs to combine technology in terms of creativity-convergence, mathematical connections, communication, improvement of evaluation quality, and TK needs to new technology acquisition, function of utilizing technology, troubleshoot problems with technology, TCK needs to mathematical value(esthetic, practical) with technology, and TPK needs to consider technology in terms of evaluation methods, teaching and learning methods, improvement of pedagogy. Therefore, when determining the direction of teacher education related to TPACK in the future, if they try to reflect these items in detail, the teachers could participate more actively and receive practical help.

Purpose: Some of the properties of the prosodic phrasing and some acoustic and phonological effects of contrastive focus on the tonal pattern of Seoul Korean is explored based on a brief experiment of analyzing the fundamental frequency(=FO) contour of the speech of the author. Data Base and Analysis Procedures: The examples were chosen to contain mostly nasal and liquid consonants, since it is difficult to track down the formants in stops and fricatives during their corresponding consonantal intervals and stops may yield an effect of unwanted increase in the FO value due to their burst into the following vowel. All examples were recorded three times and the spectrum of the most stable repetition was generated, from which the FO contour of each sentence was obtained, the peaks with a value higher than 250Hz being interpreted as a high tone (=H). The result is then discussed within the prosodic hierarchy framework of Selkirk (1986) and compared with the tonal pattern of the Northern Kyungsang dialect of Korean reported in Kenstowicz & Sohn (1996). Prosodic Phrasing: In N.K. Korean, H never appears both on the object and on the verb in a neutral sentence, which indicates the object and the verb form a single Phonological Phrase ($={\phi}$), given that there is only one pitch peak for each $={\phi}$. However, Seoul Korean shows that both the object and the verb have H of their own, indicating that they are not contained in one $={\phi}$. This violates the Optimality constraint of Wrap-XP (=Enclose a lexical head and its arguments in one $={\phi}$), while N.K. Korean obeys the constraint by grouping a VP in a single $={\phi}$. This asymmetry can be resolved through a constraint that favors the separate grouping of each lexical category and is ranked higher than Wrap-XP in Seoul Korean but vice versa in N.K. Korean; $Align-x^{lex}$ (=Align the left edge of a lexical category with that of a $={\phi}$). (1) nuna-ka manll-ll mEk-nIn-ta ('sister-NOM garlic-ACC eat-PRES-DECL') a. (LLH) (LLH) (HLL) ----Seoul Korean b. (LLH) (LLL LHL) ----N.K. Korean Focus and Phrasing: Two major effects of contrastive focus on phonological phrasing are found in Seoul Korean: (a) the peak of an Intonatioanl Phrase (=IP) falls on the focused element; and (b) focus has the effect of deleting all the following prosodic structures. A focused element always attracts the peak of IP, showing an increase of approximately 30Hz compared with the peak of a non-focused IP. When a subject is focused, no H appears either on the object or on the verb and a focused object is never followed by a verb with H. The post-focus deletion of prosodic boundaries is forced through the interaction of StressFocus (=If F is a focus and DF is its semantic domain, the highest prominence in DF will be within F) and Rightmost-IP (=The peak of an IP projects from the rightmost $={\phi}$). First Stress-F requires the peak of IP to fall on the focused element. Then to avoid violating Rightmost-IP, all the boundaries after the focused element should delete, minimizing the number of $={\phi}$'s intervening from the right edge of IP. (2) (omitted) Conclusion: In general, there seems to be no direct alignment constraints between the syntactically focused element and the edge of $={\phi}$ determined in phonology; all the alignment effects come from a single requirement that the peak of IP projects from the rightmost $={\phi}$ as proposed in Truckenbrodt (1995).

이미 일어난 사실과 다른 가상의 상황을 상상해 보는 "만약 ...다면, ...했을 텐데"와 같은 사고과정을 사후가정사고라 하며, 이러한 사고가 흔히 '후회'와 같은 부정적 감정의 경험을 수반하고 심리적 부적응과 관련 있는 것으로 밝혀졌다. 본 논문은 이러한 사후가정사고와 후회경험의 긍정적 측면, 즉 인간의 동기에 부합하거나 또는 목적을 달성하는데 도움이 되는 기능적 역할을 지지하는 연구들을 통합하여 그 응용적 가치를 논의하였다. 사회심리학자들은 사후가정사고에서 가상상황이 현실의 사실보다 나을 때와 못할 때에 따라 각각 상향적과 하향적 사후가정사고로 분류하였으며, 또한 그 구조에 따라 첨가형과 삭제형 사후가정사고로 분류하였다. 상향적 사후가정사고는 후회, 실망과 같은 부정적 감정을 동반하며 하향적 사후가정사고는 안도, 기쁨과 같은 긍정적 감정을 동반한다. 사후가정사고의 기능적 가치를 제안하는 일련의 연구를 통해, 사회심리학자들은 하향적 사후가정사고는 정서적 기능(부정적 감정의 완화와 긍정적 감정의 증대)을 상향적 사후가정사고는 미래준비기능을 수행하는 것으로 밝혀졌다. 더 나아가, 조절적 동기에 관련된 일련의 연구들에서 상향적 사후가정사고는 향상적 동기와 하향적 사후가정사고는 예방적 동기와 깊은 관련이 있는 것으로 밝혀졌다. 이러한 결과들은 사후가정사고와 후회의 경험이 반드시 통제해야만 하는 부정적인 경험이 아닌 미래의 성공을 위한 준비적 기능으로 이해될 수 있다는 것을 제안한다. 이러한 사후 가정사고의 다양한 현실사회에서의 응용 가치와 그 제한점들을 논의하였다.

본 연구에서는 차세대 기술로서 각광을 받고 있는 유비쿼터스 컴퓨팅에 대하여 사용자들이 어떠한 가치를 부여하는지를 탐색하여 그 가치 프레임워크를 구성하여 제시하였다. Keeney가 제시하였던 "가치중심사고(value-focused thinking)"의 방법을 활용하여 22명의 사용자들을 인터뷰하였고 이러한 인터뷰들에서 유비쿼터스 컴퓨팅에 바라는 바를 중심으로 435개의 진술을 확보하였다. 정형화되어 있지 않은 진술들을 정성적 방법으로 정화하여 166개의 '가치' 진술을 도출하였고 이어서 이들의 클러스터링을 통하여 사용자들이 유비쿼터스 컴퓨팅에 부여하는 가치를 내재하고 있는 37개의 목적 (objectives)을 확정하였다. 이 목적 진술들간의 관계가 유비쿼터스 컴퓨팅을 바라보는 가치의 구조이므로 이를 도출하기 위하여 포커스그룹을 시행하여 수단목적(means-objective)와 목표 목적 (ends-objective)들로 분류하였고 수단과 목적을 한 눈에 볼 수 있도록 네트워크다이어그램으로 구성을 하여 유비쿼터스 컴퓨팅을 바라보는 가치의 프레임워크를 제시하였다. 이 프레임워크는 유비쿼터스 컴퓨팅을 활용하여 비즈니스의 기회를 창출하고 심화하는 데 활용할 수 있을 것으로 보인다.

This study develops scales to measure clothing consumption values for Korean male consumers. This study conducted qualitative and quantitative research to explore a new clothing consumption value among males as well as investigate empirically the measurement of clothing consumption values. In-depth interviews and focus group interviews were collected for qualitative research on 20 Korean men in their 20s-40s who had experience with 2 types of stores in Korean men's fashion. An analysis of qualitative data based on grounded theory approaches identified 6 factors and 15 items. For the empirical research, the questionnaire which consist of 9 factors and 46 items were developed by the results of grounded theory approaches and prior studies. Final measurement scales were based on 651 data used in exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA). All subjects were in their 20s-40s. The result from CFA suggested 4 factors and 18 items with showing acceptable construct validity and discriminant validity. Therefore, this study confirmed that clothing consumption value for Korean male consumer consist of ostentatious and brand value, epistemic and possession value, conditional value, and reasonable value. These constructs will provide critical insight in understanding and segmenting Korean male consumers.

이 연구는 2013년 개별공지시가 자료를 활용하여 대구시 중구를 사례로 대도시 도심의 토지용도별 지가구조를 분석하였다. 분석결과, 지가구조가 토지용도에 따라 상당한 차이가 있는 것으로 밝혀졌다. 도심의 지가는 좁은 공간에도 불구하고 필지에 따라 변동성이 매우 크지만, 이것은 상업용지에 해당하는 것으로 주거용지나 주상복합용지에는 해당하지 않는다. 지가의 거리조락 역시 상업용지는 매우 크게 나타나지만, 주거용지나 주상복합용지는 거리조락 현상이 거의 없다. 주거용지와 주상복합용지는 지가최고점(PLVI)으로부터 가까울수록 지가가 오히려 하락하는 분화구 현상이 발견된다. 선형화한 지가함수의 회귀식에서도 상업용지와 업무용지는 지가의 거리 설명력이 크지만 주거용지나 주상복합용지는 거리 설명력도 미미하고, 특히 기울기가 음이 아닌 양의 값을 갖는다. 따라서 지금까지 일반적으로 상정되어 온 지가구조는 상업용지에는 유효하지만, 주거용지나 주상복합용지에는 유효하지 않다고 할 수 있다. 그러나 지가함수에 의한 토지용도의 분화 예측은 실제 토지이용 상황에 상당히 부합하여 알론소의 입찰지대이론의 현실적 적합성이 확인된다.

The purpose of this study was to investigate the impact of lifestyle on the perceived value of children in university students. Questionnaires were distributed to 467 university students with questions covering topics including general personal information and characteristics, lifestyle type, and value of children. First, a cluster analysis based on lifestyle showed that the subjects could be categorized into three groups: negative-leisure types, active-achievement types, and affirmative-fidelity types. The negative-leisure type was highly leisure-oriented and showed a negative self-value; the active-achievement type showed a perspective that valued personal and occupational self-development and a high level of labor-oriented value; and the affirmative-fidelity type favored materialism, seeking occupational aptitude and worth and showing a positive self-value. Second, an investigation of the impact of these three lifestyle types on the students' value of children revealed that the active-achievement type group had high level of belief in the necessity of childbirth, the affirmative-fidelity type group highly valued fulfilling an active parent role, and the active-achievement type group were inclined to delay childbirth. Further, the negative-leisure type group wanted the lowest number of children, while the affirmative-fidelity type group wanted the highest number of children. This study reveals that university students' lifestyle does have an effect on their value of children. It is therefore proposed that a value-focused population education for increasing fertility should relate not only to individuals' value of children but also to their broader lifestyle.
