  • The texture profile of frankfurter sausages was carried out by comparing the domestic(A) and imported(B) products. Fourteen character notes were identified: elasticity, surface moisture, surface smoothness, center hardness, skin toughness, cohesiveness, denseness, chewiness, moisture release, cohesiveness of mass, lumpiness, graininess, skin separation, and oiliness. Reference scales and the $0{\sim}3$ point numerical scaling method were also established. Panelists evaluated sausage A harder than the sausage B. It had higher skin separation and elasticity scores requring more chewing. Sausage B had lower surface moisture and cohesiveness of mass, but higher moisture release and graininess. Panelists commented that the sausage B were oilier but had milder tastes.

  • Objectives : Prevalence of postpartum depressive disorders reaches approximately 10-15% of childbearing women. This preliminary study was intended to explore the relationships between postpartum depressive disorders and family adaptability and cohesion. Methods : Childbearing women(n=24) were assessed for risk factors for postpartum depression before and after childbirth prospectively. At gestational age between 36th and 40th week, the questionnaire about various factors before childbirth, Edinburgh postnatal depression scale(EPDS), Family adaptability-cohesion evaluation scale (FACES), and Beck anxiety inventory(BAI) were assessed. After childbirth, for the diagnosis of postpartum depressive disorders, a structured diagnostic interview according to MINI International Neuropsychiatric Interview was performed, furthermore, the questionnaire about various factors after childbirth, EPDS, and BAI were assessed at 4-6 weeks postpartum. Results : Among various factors and scales, family adaptability and cohesion, mood symptom and change during pregnancy were associated with postpartum depressive disorder in comparison with non-postpartum depressive disorder subjects. In addition, low family adaptability and cohesion and mood change during pregnancy were significantly associated factors with postpartum depressive disorder using logistic regression analysis. Conclusion : The results suggest the postpartum depressive disorder could be related with prenatal low family adaptability and cohesion. This preliminary study, however, includes only a few subjects, so that further large-sized study will be needed to replicate our results.

  • Late-Koryeo people networks were constructed from four different history books that were written by various historic aspects in the period from king Kongmin to the final king of the Koryeo, Kongyang. All networks constructed in this study show scale free network properties as if most social networks do. Tajo-sillok preface is one of subjectively written history book that described personal history of the Lee Seong-gye and his ancestors. It is confirmed that the book is one of the most biased-written history books through network study. Jeong Do-jeon known as a Chosun dynasty projector is not greatly contributed for founding of a Chosun dynasty in network study and various historical documents as well. In this network study, we provide objective historical information in the historical situations of the late-Koryeo and during establishment procedure of Chosun dynasty. Hub nodes in network is denoted highly linked nodes, called degree. Stress centrality is a unit to measure positional importancy in the network. If we employ two factors, degree and stress centrality to determine hub node, it represents high connectivity and importancy as well. As comparing values of the degree and stress centrality, we elucidate more objective historical facts from late-Koryeo situations in this study. If we further develop and employ a new algorithm that is considered both degree and stress centrality, it is a very useful tool for determining hub node.

  • We need a component-based system to reflect software changes in user's requirements, to implement a system at a rapid speed as well as to efficiently manage the system in a maintenance phase and to easily change software. Moreover, the component-based system has a merit in development cost. However, existing component development methodology for implement of component-based system is inefficient in object identification for component identification. Moreover, the existing component development methodology also fails to provide any method to identify system component. It merely provides procedures and methods to identify business component focused on a whole system domain. In addition, it has another problem that it considerably relies on developer's experiences and intuitions for component identification. Therefore, according to this paper, RUP (Rational Unified Process) is applied from a requirement analysis phase to an object identification phase in order to improve the inefficiency of object identification. In addition, this paper procedures and methods for system component identification, and identifies business components based on the identified system component, rather than on the whole system domain. This paper also provides and applies cohesion metric and coupling metric so as to overcome the problem that component identification depends on developer's intuitions and experiences. Accordingly, the component identification method proposed in this paper, may identify components more effectively based on facility of object identification, functional reusability of components, traceability, and independence of components.

  • As the importance of software measurement increases, there are more researches developing the new software measure. Given the importance of object-oriented development techniques, one specific area where this has occurred is coupling measurement in object-oriented systems. This thesis presents the coupling measure COM based on the methods and OOC based on the classes in measuring the coupling of object-oriented systems. And, it evaluates them using the coupling properties suggested by Briand while it compares them with other coupling measures by applying them to a system developed in the language of C++programming language.

  • The purpose of this study is to fine out whether melodic percussion playing group program affects the team cohesion and team efficacy of youth soccer players. In this study fifty seven middle school soccer players were participated. The participants were assigned to either a melodic percussion playing group or a control group. In order to identify the effectiveness of music program, assessments were conducted using the team cohesion and team efficacy scales before and after the program. The results of comparison analysis through t-test are as follows. First, in the posttest of team cohesion between groups, the experimental group showed a significant difference over the control group. In the pretest and posttest examinations within a experimental group, the group also showed a significant difference. Second, in the posttest of team efficacy between groups, the experimental group showed a significant difference over the control group. In the pretest and posttest examinations within a experimental group, the group also showed a significant difference. These results of this study suggest that melodic percussion playing group program may be an effective intervention tool to improve team cohesion and team efficacy of youth soccer players.

  • During chlorination processes dissolved organic nitrogen (DON) can form toxic nitrogenous disinfection byproducts and organic chloramines which have little or no bactericidal activity. DON needs to be removed before chlorination processes to reduce the formation of those products. This study investigated the removal of DON from surface water and reclaimed water by coagulation with aluminum sulfate (alum) and a cationic polymer (polyDADMAC). Removal characteristics of dissolved organic carbon (DOC) and ultraviolet absorbance at 254 nm ($UVA_{254}$) were compared with that of DON. Coagulation with alum removed DON, DOC, and $UVA_{254}$ with similar trends, but the removal of $UVA_{254}$ was highest. A dual coagulation strategy of alum and cationic polymer improved the removal of DON. Coagulation with cationic polymer alone was not effective due to its narrow range of charge neutralization. DON in reclaimed water was easier to remove than that in surface water, and higher molecular weight fraction (>10,000 Da) of DON was preferentially removed.

  • 객체지향 시스템의 개발은 클래스를 통해서 이루어진다. 즉, 문제 영역에 존재하는 중요한 대상 또는 개념을 클래스로 모델링하고, 이로부터 생성된 객체들 사이의 메시지 교환을 통해서 시스템은 구축된다. 또한, 클래스는 정보 은닉을 제공함으로써, 객체지향 시스템의 재사용성과 유지보수성에 상당한 기여를 한다. 그러나, 설계 단계에서 실세계의 대상을 부적절하게 모델링하거나, 또는 유지보수 단계에서 클래스에 무분별한 변경을 가하는 경우 클래스의 품질은 악화될 수 있고, 이는 결국 시스템을 유지보수 하거나 확장하는데 상당한 장애를 초래한다.응집도는 모듈의 구성 요소들 사이의 연관성 정도를 나타내는 척도로서 전통적으로 모듈의 품질을 평가하기 위한 기준으로 사용되어 왔다. 이 논문에서는 클래스의 품질을 평가하는 방법으로서의 클래스 응집도를 제안한다. 즉, 클래스가 실세계의 대상을 적절하게 모델링한다면, 그 구성요소들 사이에 밀접한 관련이 있고 결국 높은 응집도를 가지게 될 것이다. 반대로 실세계의 대상에 대한 적절한 모델이 아니라면, 그 클래스의 구성 요소들 사이에는 밀접한 관련성이 없을 것이고 따라서 낮은 응집도를 보일 것이다.Abstract Object-oriented systems are developed by means of classes; that is, classes captures the essential entities or concepts in the problem domain, and the system is embodied by the interactions of objects instantiated from the classes. In addition to the basic units of object-oriented systems, classes serves as the units of encapsulation, which considerably promote the modifiability and the extensibility of them. However, improper modeling in the design phase or uncontrolled changes during the maintenance phase can degrade the quality of classes, which leads to systems cumbersome to maintain and extend.Cohesion refers to the degree of connectivity among the elements of a single module, and is being used as a factor which characterizes the quality of a module. In this paper, we propose a new cohesion metric for assessing the quality of classes. If a class captures properly the essential features of objects, the members of the class surely have strong relationship among them. On the contrary, the poor relationship among class members can indicate that the class is not a proper model of objects.
