최근 VHDL 코딩 및 합성방법에 의한 설계가 널리 사용되고 있다. 집적도가 증가함에 따라 VHDL에 의한 설계 또한 그 분량이 증가하여 많은 코딩오류가 발생하고 있으며, 이를 검색하는데 많은 시간과 노력이 소요되고 있다. 본 논문에서는 VHDL 행위-레벨 설계를 대상으로 코딩오류를 검색하는 방법을 제안하였다. 그 방법에 있어서는 검색패턴을 생성하여 오류가 없는 응답과 설계의 응답을 비교함으로써 설계오류를 찾는 방법을 택하였다. 따라서 본 논문에서는 코딩오류를 검색하기 위한 검색패턴을 생성하는 알고리듬을 제안하였다. 검색패턴 생성은 각 코드에 대해 수행하며, 할당오류와 조건오류를 구분하여 수행하였다. 패턴생성을 위해 VHDL 코드를 CDFG로 변환하여 사용하며, CDFG상의 경로를 탐색하여 패턴생성에 필요한 정보를 추출한다. 경로탐색은 오류가 발생하였다고 가정한 지점으로부터 역방향 탐색과 정방향 탐색을 수행하여 패턴을 생성한다. 제안한 알고리듬은 C-언어로 구현하였다. 펜티엄-Ⅱ 400MHz의 환경에서 여러 가지 VHDL 행위-레벨 설계를 대상으로 제안한 알고리듬을 적용하였다. 그 결과, 고려한 모든 설계의 모든 코드에 대한 검색패턴을 생성할 수 있었으며, 가정한 모든 오류를 검색할 수 있었다. 검색패턴 생성에 소요되는 시간은 고려한 모든 대상 설계에서 1초 미만의 CPU 시간을 보여 속도면에서도 매우 우수함을 나타내었다. 따라서 본 논문에서 제안한 검색방법은 VHDL에 의한 설계에서 설계검증에 필요한 시간과 노력을 상당히 감소시킬 것으로 기대된다.

This study examined customer misbehaviors in retail settings by identifying behavioral patterns and exploring behavioral backgrounds and consequences from the employee's perspectives. Qualitative data were collected from an individual interview method, and 222 interviews were analyzed. Customer misbehavior was categorized into unethical returns, problem behaviors in service encounters, unreasonable demands, shoplifting/fraud, ill-mannered behaviors, and selfish behaviors. Behavioral backgrounds included dissatisfaction, unreasonable expectations, actively benefiting of service failures, taking advantage of service standards, illegitimate complaints, monetary gains, transferring responsibility, and demanding special treatment. Employees experienced stress facing misbehaving customers with no other choice except to accept misbehaviors and learned misbehaviors as customers themselves. The study further discusses the implications.

Customer misbehavior is a behavior that disrupts generally accepted behavioral norms in consumption situations. This study examined customer misbehavior in retail settings by identifying behavioral patterns and exploring behavioral backgrounds and consequences from a customer viewpoint. Qualitative data were collected from individual in-depth interviews, and 149 interviews were analyzed. Customer misbehavior was categorized into unethical returns, problem behaviors in service encounters, shoplifting/fraud, ill-mannered behaviors, and selfish behaviors. Motivations included monetary gain, adventurism, perceived acceptability of misbehavior, planned unfair complaints, and retaliation. Customers showed a negative image to unkind employees and stores yielding to misbehaviors that were learned and socialized among customers. The study further discusses implications.

Various methods for detecting changes in response behaviors of indicator specimens are presented for monitoring effects of toxic treatments. The movement patterns of individuals are quantitatively characterized by statistical (i.e., ANOVA, multivariate analysis) and computational (i.e., fractal dimension, Fourier transform) methods. Extraction of information in complex behavioral data is further illustrated by techniques in ecological informatics. Multi-Layer Perceptron and Self-Organizing Map are applied for detection and patterning of response behaviors of indicator specimens. The recent techniques of Wavelet analysis and line detection by Recurrent Self-Organizing Map are additionally discussed as an efficient tool for checking time-series movement data. Behavioral monitoring could be established as new methodology in integrative ecological assessment, tilling the gap between large-scale (e.g., community structure) and small-scale (e.g., molecular response) measurements.

The main purpose of this study is to suggest fundamental materials and a guideline for design through grouping of the users' use route patterns and analyzing determinants to choose those route patterns in urban parks. Study sites were Jungang, Dlseong, and Beomeo park, where located Taegu city-Key results obtained through a series of investigation were as follows : When Users come in and out urban parks, most orientations of their use routes were counterclockwise, and not in such cases, greatly affected by facilities arrangement. There were a large number of users in the main route placed the principal facilities. Users' use route patterns were grouped by their characteristics, which were circulation, semi-circulation, irregular, and piston type. And all the types except piston type can be subdivided into spoon and loope type. Factors analysis to the types produced five meaningful patterns of variables. Five factors were named as dimension of characteristics : Park composition factor, facilities use factor, users' personal factor, park use behavioral factor, routes choice factor.

Russian sturgeon (Acipenser gueldenstaedtii) is commercially important in Korea because its caviar is highly prized. Although the early ontogeny of the species has been described, behavioral modifications in response to various light intensities or diel photoperiodicity patterns have not been studied extensively. The objective of the present study was to examine the behavioral characteristics of hatchery-produced A. gueldenstaedtii prelarvae over a diel photoperiodic cycle. During a diel light cycle comprising 16 h of daylight (450 lx), 4 h of dim light (10 lx), and 4 h of darkness (< 1 lx), newly hatched A. gueldenstaedtii prelarvae exhibited negative phototaxis in daylight (day 0-day 2), and this early behavior was not significantly affected by changes of light intensities. Rheotactic and non-rheotactic aggregation into schools was typical between days 3 and 6. Under the diel light cycle conditions described, rheotaxis was not influenced by environmental light intensity as much as non-rheotactic schooling behavior. Post-schooling behavior, which progressed from day 7 to day 8, did not change significantly during the diel light cycle. The data from the present study could be of practical value in developing a visual guide for assessing the fitness and quality of Russian sturgeon prelarvae under diel light cycle conditions in hatcheries.

This study was performed to develop cold-heat and deficiency-excess pattern identification for dementia, as well as for standard Korean medicine diagnosis and treatment. Five experts comprised of 4 neuropsychiatrists of Korean medicine and 1 statistician to develop cold-heat and deficiency-excess pattern identification for dementia. We searched studies about pattern identification and selected 507 articles using Oasis search terms provided by the KIOM. As a result, 10 pattern identification research study were recruited. Moreover, we analyzed neuropsychological assessments for dementia that evaluate Behavioral and Psychological Symptoms of Dementia (BPSD) and cognitive function using experts conferences and we selected neuropsychological instruments using pattern identification. Six cold patterns, six heat patterns, ten deficiency patterns, and four excess patterns were identified according to the cold-heat and deficiency-excess pattern identification of dementia. We selected the Caregiver-Administered Neuropsychiatric Inventory and the Korean Mini-Mental State Examination as neuropsychological assessments of dementia, which examine behavioral symptoms and cognitive function, suspectively. We formed positive and negative correlation between Korean medicine pattern identification and neuropsychological assessments for dementia. We developed and suggested a forecast module of pattern identification for dementia. But, it is necessary to perform additional clinical trials to verify its validity and accuracy.
