본 연구는 게임 상황에 대한 정보를 제공해주는 청각적 피드백에 대한 사용자의 인지 정도와 사용자 경험 요소들의 관계에서 재미의 역할을 살펴보았다. 대학생 100명을 대상으로 모바일 게임 '클래시 로얄'을 플레이 한 후 이 게임에 대한 사용자 경험을 조사했다. 프로세스 매크로를 통해 98명의 데이터를 분석한 결과, 청각적 피드백을 인지할수록 재미와 몰입, 지속적 이용의도가 늘어났고, 재미는 몰입과 지속적 이용의도에 대한 인지된 청각적 피드백의 영향을 매개했다. 이러한 연구 결과는 게임 정보의 제공이라는 음향 효과의 기능적 가치에 대한 게임 연구와 개발에 도움이 될 것이다.

본 실험은 초고압 동결 처리 방법에 의한 돈육의 특성을 대기압 동결 처리와 비교하기 위하여 시행되었다. 본 실험의 결과에 의하면, PSF은 높은 압력 범위에서는 효과적인 잠열의 제거에 기인하여 조직 내 작고 균일한 얼음 결정을 형성함으로써 식품의 품질을 향상시킬 수 있지만, 100 MPa의 mild pressure 범위 조건에서는 그 효과가 미약하거나 오히려 식품에 악영향을 나타낼 수 있었다. 반면에 높은 압력 범위의 PAF은 돈육의 연도 증가 및 심한 변색에 기인하여 육질을 저하시킬 수 있었지만, 본 실험에서 사용한 압력 범위에서는 잠열의 감소에 의하여 PSF보다 따른 동결이 가능하여 효과적인 동결 처리 방법으로 판단되었고, 결국 초고압 동결처리는 압력의 범위에 따라 응용 방법을 적정하게 사용함으로서 식품의 품질을 향상시킬 수 있으리라 판단된다.

The purpose of this study is to develop measurement items for quality cost in service industries. Quality cost is necessary in order to evaluate quality management activities. It is clear that the quality cost in service industry is different from manufacturing industry. Generally, in service industries, quality cost is very difficult to assess because it has a unique characteristics. This paper proposes an effective method for measuring quality cost in service industries. Based on the PAF (Prevention, Appraisal, Failure) cost model, we utilizes the concept of five demensions in SERVQUAL which are tangibles, reliability, responsiveness, assurance, empathy. This paper also presents to a standard model for quality cost measurement in service industries.

This paper introduces m analysis framework and procedure for the support of the cognitive error analysis of emergency tasks in nuclear poler plants. The framework provides a new perspective in the utilization of influencing factors into error prediction. The framework can be characterized by two features. First, influencing factors that affect the occurrence of human error me classified into three groups, i.e., task characteristic factors(TCF), situation factors(SF), and performance assisting factors(PAF). This classification aims to support error prediction from the viewpoint of assessing the adequacy of PAF under given TCF and SF. Second, the assessment of influencing factors is made by each cognitive function. Through this, influencing factors assessment and error prediction can be made in an integrative way according to each cognitive function. In addition, it helps analysts identify vulnerable cognitive functions and error factors, and obtain specific nor reduction strategies. The proposed framework was applied to the error analysis of the bleed and feed operation of nuclear emergency tasks.

Mannheim introduced the concept of a pair of curves, called as Mannheim partner curves, in 1878. Until now, Mannheim partner curves have been studied widely in the literature. In this study, we take into account of this concept according to Positional Adapted Frame (PAF) for the particles moving in the 3-dimensional Euclidean space. We introduce a new type special trajectory pairs which are called Mannheim partner P-trajectories in the Euclidean 3-space. The relationships between the PAF elements of this pair are investigated. Also, the relations between the Serret-Frenet basis vectors of Mannheim partner P-trajectories are given. Afterwards, we obtain the necessary conditions for one of these trajectories to be an osculating curve and for other to be a rectifying curve. Moreover, we provide an example including an illustrative figure.

기존(旣存)의 지체모형(遲滯模型)은 지체(遲滯)의 분석(分析)을 위하여 무작위도착(無作爲到着)(Random Arrival)을 가정(假定)하고 있으므로 가로망상(街路網上)에서 군(群)의 형태를 이루는 교통류(交通流)에 대한 실질지체(實質遲滯)를 정확히 분석(分析)하지 못한다. 이러한 단점(短點)을 보완(補完)하기 위하여 미국(美國) 도로용량편람(道路容量便覽)(HCM)에서는 연동화보정계수(連動化補正係數)(PAF)를 사용하여 보다 정확한 지체(遲滯)의 분석을 시도(試圖)하고 있다. 그러나 미국(美國)의 도로용량편람(道路容量便覽)에서 제시(提示)하고 있는 연동화보정계수(連動化補正係數)는 차량군(車輛群)의 도착형태(到着形態), 차량군비(車輛群比) 등에서 많은 문제점(問題點)을 내포(內包)하고 있다. 본(本) 연구(硏究)는 이러한 문제점(問題點)에 대하여 미국(美國) NCHRP 연구결과(硏究結果)를 참고(參考)로 하여 우리나라 실정(實情)에 적용(適用)할 수 있는 교차점(交叉點) 지체모형(遲滯模型)과 연동화(連動化) 분석모형(分析模型)을 제안(提案)하고 기존(旣存)에 제시(提示)된 모형(模型)의 결과(結果)와 비교(比較)함으로서 각 모형(模型)들간의 차이점(差異點)과 예측력(豫測力)을 이론적(理論的)으로 검토(檢討)하여 본다.

Objectives : This study was designed to investigate the effects of SuJeom-san(SJS) extract in rats with caerulein-induced acute pancreatitis (AP). Methods : We examined changes of pancreatic weight, histological, immunohistochemical and gene expression of cyclooxygenase (COX-2). Thirty-six adult male Sprague-Dawley rats were divided into six groups as follow: normal(Nor), caerulein-induced (Con), caerulein + cefotaxime sodium(CT), caerulein + SJS 3 mg/kg(SJSA), caerulein + SJS 6 mg/kg(SJSB) and caerulein + SJS 12 mg/kg(SJSC) groups. Pancreatic tissues of rats from all groups were removed for histological observation and light, and electron microscopic examination. Platelet activating factor(PAF) and Interleukin-6(IL-6) levels were determined spectrophotometrically. Results : The ratio of pancreas/body weight was significantly(p<0.05) increased in the Con compared with Nor, but significantly(p<0.05) decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Caerulein administration significantly increased(p<0.05) the levels of amylase, but SJSA, SJSB, SJSC and CT significantly(p<0.05) reduced the levels of these enzymes. The levels of platelet activating factor(PAF) increased in Con compared with Nor, but decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Interleukin-6(IL-6) levels increased significantly in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The levels of tumor necrosis factor(TNF)-${\alpha}$ levels increased in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The COX-2 positive materials were observed in the pancreas of the Con, but these positive materials were decreased in the SJS extract treatment group. Conclusion : SJS is potentially capable of limiting pancreatic damage during AP by restoring the fine structure of acinar cells and tissue; therefore, we conclude that SJS may have beneficial effects in the treatment of caerulein-induced AP.

In previous study for correlation between P-wave Signal Averaged Electrocardiography (SAECG) and Paroxysmal Atrial Fibrillation (PAF) subjects, we showed that the duration of P-wave in subjects is longer than in controls. In this respect, the P-wave SAECG is a new method proving to be an accurate and independent noninvasive marker for the risk of PAF. To prove this suggestion, accurate detection and alignment of P-wave are indispensible. In previous study, we measured P-wave duration by manual. So it was not accurate and consistent. To measure the P-wave duration accurately and automatically, we have developed an automatic algorithm for P-wave duration measurement. We showed that the duration of P- wave in the subjects is longer than in controls with this algorithm.
