  • 본 연구에서는 해설판의 '숲의 명칭' 또는 '숲의 치유 효과에 대한 정보'가 이용객의 회복환경지각(perceived environmental restorativeness: PER)과 전반적 치유효과지각(perceived healing effectiveness: PHE)에 미치는 영향을 조사하였다. 2015년 5-6월 중 연구대상지역인 무등산국립공원 내 '치유의 숲길' 방문객을 대상으로 편의표본추출 방법을 통해 247명의 표본이 선정되었으며 자기기입식 설문지기법을 통하여 데이터 수집이 이루어 졌다. 본 연구의 실험을 위해 '치유의 숲길'을 따라 설치한 해설판(숲의 명칭과 치유의 숲길의 치유효과에 관한 내용 포함)을 읽은 응답자는 플라시보그룹, 해설판을 읽지 않은 응답자는 컨트롤그룹으로 간주하였다. 분석결과, 컨트롤과 플라시보그룹 간 PER과 PHE는 전반적으로 차이가 없는 것으로 나타났다. 그러나 PER의 구성 요인별 비교 결과에 따르면 플라시보그룹이 '벗어남'(being away) 요인에서 컨트롤그룹에 비해 긍정적인 수치를 나타냈다. PER의 4개 요인(벗어남, 짜임새, 매혹감, 적합성) 모두 PHE에 영향을 미치는 것으로 조사되었으며(P<0.001) 이들 4개 요인은 PHE의 51.1%를 설명하였다. PHE에 미치는 영향력은 짜임새, 벗어남, 적합성, 매혹감 순으로 크게 나타났다. PER에 미치는 플라시보 효과는 남성, 저연령층, 저 방문경험 그룹에서 나타났으며, PHE에 미치는 플라시보 효과는 남성, 소그룹, 혼자서 또는 친척/가족 동반그룹, 저 방문경험 그룹에서 발견되었다. 관리적 관점에서 몇 가지 시사점을 제시하였다.

  • This research aims to analyze and compare the objective and subjective evaluation criteria for home appliances. In addition, this research examined the correlation between those evaluation criteria. Furthermore, consumers are divided by the level of the differences between those criteria; consumer groups whose subjective evaluation level for the quality of home appliances is greater than objective evaluation level, consumer groups whose subjective evaluation level is almost the same, and consumer groups whose subjective evaluation level for the quality of home appliances is lower than objective evaluation level, and this study investigated the differences those three groups by the socio-demographic characteristics and consumers' behavior in the stage of purchase. Results of this research could be summarized as follows. First of all, there were statistically significant between the level of the objective and subjective evaluation in the quality of home appliances. Second, when consumers purchased the expensive home appliance, imported-brand home appliance, home appliances in department store, the level of subjective evaluation level for the quality of home appliances is higher than objective evaluation level. Third, the level of satisfaction for the price, quality, AS, overall satisfaction, and the level of willingness to repurchase were higher in consumer groups whose subjective evaluation level was higher than objective evaluation level.

  • We examined some problems in speaker identification procedures: transformation of acoustic parameters into auditory scales, invalid measurement values, and comparability of spectral energy values across the frequency range. To resolve those problems, we analyzed the acoustic spectral energy of three Korean numbers produced by ten female students from narrow-band spectrograms at 19 proportional time points of each voiced segment. Then, cells of the first five spectral matrices were averaged to form a matrix model for each speaker. The correlation coefficients and sum of the absolute amplitude difference in each pair of the spectral models of the ten subjects were obtained. Also, some individual matrix models were compared to those of the same subject or the other subject with a similar spectral model. Results showed that in numbers '2' and '9' subjects could not be clearly distinguished from the others but in number '4' it shed some possibility of setting threshold values for speaker identification if we employed the coefficients and the sum of absolute difference. Further studies would be desirable on various combinations of the range of long-term average spectra and the degree of signal pre-emphasis.

  • MIM capacitor has been investigated for the next generation DRAM. Conventional poly-Si bottom electrode cannot satisfy the requirement of electrical properties and comparability to the high k materials. New bottom electrode material such as ruthenium has been suggested in the fabrication of MIM structure capacitor. However, the ruthenium has to be planarized due to the backend scalability. For the planarization CMP has been widely used in the manufacture of integrated circuit. In this research, ruthenium thin film was Polished by CMP with cerium ammonium nitrate (CAN)base slurry. HNO3 was added on the CAN solution as an additive. In the various concentration of chemical and alumina abrasive, ruthenium surface was etched and polished. After static etching and polishing, etching and removal rate was investigated. Also microroughness of surface was observed by AFM. The etching and removal rate depended on the concentration of CAN, and HNO3 accelerated the etching and polishing of ruthenium. The reasonable removal rate and microroughness of surface was achieved in the 1wt% alumina slurry.

  • The purpose of the study was to investigate defect cases in residential interior design, to identify the state of defects, and to categorize types of defect and disputes. In addition, consumer appraisal to residential interior design service were analyzed. The results of this study could provide fundamental information regarding the defects and claims in residential interior design. First, we did literature review for defect disputes in architectural design and interior design. We identify the definition of defects by building life cycle, by state of construction, by activity, and by design performance. Second, we analysed interior design defects cases reported in Korea Consumer Agency & Ministry of Land, Infrastructure and Transport. A total of 49 cases of defect disputes in residential interior design from 2000 to 2015 were investigated. As a result, many defects appeared during the construction stage. A majority of defects cases fall into insulation, water-proofing/leakage work. In terms of design aspects claim, functional and aesthetic defects were claimed. Third, from Consumer Market Evaluation Indicators, raw data from 500 respondents were investigated for the housing repair and interior design. It is found that information comparability, responsiveness to consumer claim, price, and safety are important factors for consumer satisfaction in interior design.

  • The purpose of this study was to determine if international guidelines differ in their recommendations concerning additive therapy for advanced, but potentially curable, gastric cancer. A systematic search of the English and German literature was conducted in the databases Medline, Cochrane Database, Embase, and PubMed. The search terms used were 'guidelines gastric cancer,' 'guidelines stomach cancer,' and 'Leitlinien Magenkarzinom.' Six different guidelines published after January 1, 2010, in which the tumors were classified according to the seventh edition of the TNM system (2010), were identified. Although the examined guidelines were based on the same study results, their recommendations concerning accompanying therapy for gastric cancer differ considerably. While perioperative chemotherapy is recommended in Germany, Great Britain, and large parts of Europe, postoperative adjuvant radiochemotherapy or perioperative chemotherapy is recommended in the USA and Canada. In Japan, postoperative adjuvant chemotherapy is recommended. The results of identical studies were interpreted differently in different countries. Since considerable effort is required for each country to separately test relevant studies for their validity and suitability, an international cooperation could simplify the creation of a common basis for guidelines and contribute to improved comparability of international guidelines.

  • 단백질의 구조적 동등성을 평가를 위한 형태 기반의 기술자에 대한 연구는 제한적으로 이루어지고 있으며 대부분 지역적 특성 값으로 표현된 지역적 접근 방법이 다수를 이루고 있다. 지역적 특성과 전역적 특성을 포함하는 형태기술자의 경우 각 특성들이 동등한 중요도로 결합되어 있다. 본 연구에서는 선형 회귀분석을 적용하여 각 특성에 대한 중요도를 최적화하여 형태기술자를 재정의 하였다. 최적화된 형태기술자를 단백질의약품인 인슐린 모델에 적용하여 구조적 동등성을 평가할 수 있는 방법론을 제시하였다. 최적화된 형태기술자는 동일한 그룹에 속한 인간 인슐린 단백질 모델과 지역적으로 다른 구조를 가지는 인슐린 아날로그 그룹을 명확히 구분할 수 있음을 확인하였고 이러한 성능은 이전 연구의 형태기술자와 3D 저니크 기술자보다 더 좋은 성능을 보였다. 또한 제안한 방법은 고해상도 단백질 3차 구조 정보를 활용하여 유사성을 판별한 RMSD 방법과 유사하게 서로 다른 표면 구조를 가지는 단백질을 구별할 수 있음을 확인하였다. 이러한 결과로부터 본 연구에서 제시하는 형태기술자 및 최적화된 동등성 평가 함수는 SAXS 분석과 같이 저해상도 단백질 표면 모델을 확보할 수 있는 분석에 적용하여 단백질의 구조적 동등성을 판별할 수 있는 기반을 제공할 수 있을 것으로 판단된다.
