This study aims to investigate and analyze the utilization perception of members of head families based on a survey on the history, folklore, architectural resources of head families. In order to identify the direction of utilization of Jeonnam head family resources, tangible and intangible resources, and spaces and places to contain programs were researched. The results of the study were summarized as follows. 1) Head family houses in Jeonnam could be categorized into head families that preserved the original form of head family houses, head families that preserved a part of head family houses, head families that newly built head family houses while the original forms thereof have disappeared, and relocated head families of which eldest grandsons no longer reside, where only the sites of the head family houses remain or relocated to a different place. 2) In the case of perception of members of head families on the utilization of head family resources, 27 head families consented to the utilization, 35 head families opposed to the utilization, and 6 head families were undecided on the utilization out of a total of 68 head families. 3) The results of investigating and analyzing the desired type of programs of each head family by categorizing the programs into lodging, food, meditation, education, and tourism, as many as four programs were desired, while some families desired 2 or 3 programs at the lowest, showing an overlapping characteristic.

Mechanical parts are often grouped into part families based on the similarity of their shapes, to support efficient manufacturing process planning and design modification. The 2-part sequence papers present similarity assessment techniques to support part family classification for machined parts. These exploit the multiple feature decompositions obtained by the feature recognition method using convex decomposition. Convex decomposition provides a hierarchical volumetric representation of a part, organized in an outside-in hierarchy. It provides local accessibility directions, which supports abstract and qualitative similarity assessment. It is converted to a Form Feature Decomposition (FFD), which represents a part using form features intrinsic to the shape of the part. This supports abstract and qualitative similarity assessment using positive feature volumes.. FFD is converted to Negative Feature Decomposition (NFD), which represents a part as a base component and negative machining features. This supports a detailed, quantitative similarity assessment technique that measures the similarity between machined parts and associated machining processes implied by two parts' NFDs. Features of the NFD are organized into branch groups to capture the NFD hierarchy and feature interrelations. Branch groups of two parts' NFDs are matched to obtain pairs, and then features within each pair of branch groups are compared, exploiting feature type, size, machining direction, and other information relevant to machining processes. This paper, the second one of the two companion papers, describes the similarity assessment method using NFD.

이 연구는 가정과교육에서 지향하는 실천 개념은 어때야 하는지를 아리스토텔레스의 덕론에서 덕의 분류에서 실천적 지혜(phronesis)의 위치를 파악하고 다른 덕과의 관계에 대한 논의를 중심으로 살펴보았다. 실천적 지혜는 praxis로 이끄는 덕이기 때문에 우리나라 교육과정에서 실천교과라고 명시되어 있는 가정과교육의 실천적 본질을 이해하는 데에 핵심적 개념이라고 볼 수 있다. 아리스토텔레스는 인간의 영혼을 이성적 부분과 비이성적 부분으로 나누고 이성적 부분을 다시 인식적 부분과 사량적 부분으로 나누었다. 영혼의 비이성적 부분을 식물적 부분과 욕구적 부분으로 나누었다. 인식적 부분에 해당하는 덕을 지적 덕, 욕구적 부분에 해당하는 덕을 도덕적 덕이라 하였다. 실천적 지혜는 인간 정신의 이성적 부분 중 사량적 부분에 해당하는 지적 덕 중에 하나이다. 이와 같은 분류에 기초할 때 실천적 지혜는 좁은 의미에서 praxis와 관계하는 덕으로 sophia와 구별되며, techne와도 구별된다. 넓은 의미에서 실천적 지혜는 techne를 포함하는 사량적 부분의 덕이다. 실천적 지혜는 도덕적 덕과 상호 밀접한 관계를 가지며 올바른 욕구와 logos를 따라 선택한 행동에 이르게 한다. 이 연구의 논의를 기초로 가정과교육은 실천 개념의 범위를 어떻게 설정하여야 하는가의 과제와 실과와 기술과의 관련성은 어떻게 해석하는 것이 옳은지의 과제를 해결할 수 있을 것으로 보았다. 이 연구에서는 가정과교육에서 지향하는 praxis의 의미를 잠정적으로 '도덕적으로 실천하는 행동, 선을 구체화 또는 실현하는 행동, 혹은 최선의 선을 추구하는 좋은 삶'으로 보았다. 실천교과로서의 가정과교육에서 실천적 지혜를 가진 사람의 의미는 '개인 및 가정생활에서 일어나는 실천적 문제의 구체적 상황에서 자신뿐만 아니라 모두를 위해 최고의 선을 구체화하는 행동(praxis)을 할 수 있는 사람'이다. 실천적 지혜와 다른 덕과의 관계를 살펴본 결과 실천적 지혜를 통해 이론과 실천을 통합할 수 있으며, 도덕적 덕과 불가분리의 관계를 맺고 있음을 알 수 있었다. 그러므로 아는 것이 행동하는 것으로, 행동하는 것이 잘 행동하는 것으로 가게 해주는 덕이 실천적 지혜이므로, 실천교과로서의 가정과교육을 통하여 실천적 지혜를 가진 사람으로 교육할 사명을 다해야 할 것이다.

Some characteristics of germ cell differntiations during spermiogenesis and mature sperm ultrastructure in male Phacosoma japonicus were investigated by transmission electron microscope observations. The morphology of the spermatozoon of this species has a primitive type and is similar to those of other species in the subclass Heterodonta. Morphologies of the sperm nucleus and the acrosome of this species are the cylindrical type and cap shape, respectively. The spermatozoon is approximately 45-50 ${\mu}m$ in length, including a long curved sperm nucleus (about $3.70{\mu}m$ long with 45 $^{\circ}$ of the angle of the nucleus, an acrosome (about $0.55{\mu}m$ in length), and tail flagellum (about 42-$47{\mu}m$)The axoneme of the sperm tail shows a 9+2 structure. As some characteristics of the acrosomal vesicle structures, the basal and lateral parts of basal rings show electron opaque part (region), while the anterior apex part of the acrosomal vesicle shows electron lucent part (region). These characteristics of the acrosomal vesicle were found in the family Veneridae and other several families in the subclass Heterodonta. These common characteristics of the acrosomal vesicle in the subclass Heterodonta can be used for phylogenetic and systematic analysis as a taxonomic key or a significant tool. The number of mitochondria in the sperm midpiece of this species are four, as one of common characteristics appear in most species in the family Veneridae and other families in the subclass Heterodonta. However, exceptionally, only three species in Veneridae of the subclass Heterodonta contain 5 mitochondria. The number of mitochondria in the sperm midpiece can be used for the taxonomic analysis of the family or superfamily levels as a systematic key or tools.

This study composed spatial cognition tasks within the system of geometric area to study children's spatial cognition development systematically. It surveyed children's execution of direction, rotation, symmetry, conjugation, and part/whole cognition tasks. A spatial geometry cognition task set (consisting of total 27 sub-tasks) was presented to 60 children (20 each in groups of 3-, 4-, and 5-year-old) in order to confirm how children's execution of spatial geometry cognition changed depending on children's age and sex as well as if the execution of the spatial geometry cognition showed a difference after each task area. As a result, the execution of the whole direction task and the part/whole task gradually increased between age 3 and age 5. The execution of the whole rotation task, whole symmetry task, and whole conjugation task rapidly increased between age 3 and age 4. Significant sexual difference did not appear in the execution of spatial geometry cognition tasks. The execution of the conjugation and part/whole task was high in each task area, and the execution of the direction, rotation, and symmetry task was relatively low. In addition, the difference of task execution appeared in the sub-tasks of direction, symmetry, and conjugation areas. This result suggests the theoretical discussion possibility of children's spatial geometry cognition development. In addition, the empirical results of this study can be applied to child education plans and activity compositions appropriate for child development.

Background: Family physicians (FPs) play an important role in cancer control. The aim of this study was to understand the functions of FPs in cancer control and to explore FPs' perceptions of their own roles and the difficulties they face in cancer control in Karabuk province, Turkey. Methods: The study consisted of two methodological parts. The qualitative part included a descriptive study in which data were collected from 87.5% (n=56) out of all FPs in Karabuk using a questionnaire. In the quantitative part, in-depth interviews with 15 FPs were conducted and analyzed through content analysis. Results: Half of the FPs (50.0%) provided cancer prevention information for their registered people, focusing on especially smoking cessation. In the last three months, the proportion of FPs who had not invited anyone to screenings was 37.5% for the pap test, 26.8% for the mammography, 19.0% for the fecal occult blood test and 34.5% for the colonoscopy. Only 16.1% of them reported that they made home visits for cancer patients. In the qualitative part of study, the following themes were highlighted: the perceived responsibilities of FPs regarding cancer control; the effect of geographically undefined working area of FPs; the issues with coordination between FPs and specialists; the effect of the number of primary care team members. Conclusions: Cancer control services provided by FPs have significant problems in terms of the FPs' approach to the services and their content, continuity and coordination.

Some characteristics of the formations of acrosomal vesicles during the late stage of spermatids during spermiogenesis and taxonomical charateristics of sperm morphology in male two species (Saxidomus purpurata and Meretrix petechialis) in the family Veneridae were investigated by electron microscope observations. In two species, the morphologies of the spermatozoa have the primitive type and are similar to those of other bivalves in that it contains a short midpiece with five mitochondria surrounding the centrioles. The morphologies of the sperm nuclear types of S. purpurata and M. petechialis in Veneridae have the curved cylindrical and cylinderical type, respectively. And the acrosome shapes of two species are the same cap-shape type. In particular, the axial filament is not found in the lumen of the acrosome of two species, however, subacrosomal material are observed in the subacrosomal spaces between the anterior nuclear fossa and the acrosomal vesicle of two species. The spermatozoon of S. purpurata is approximately 46-$52{\mu}m$ in length, including a curved sperm nucleus (about $3.75{\mu}m$ in length), a long acrosome (about $0.40{\mu}m$ in length),and a tail flagellum (about 45-$47{\mu}m$ long). And the spermatozoon of M. petechialis is approximately 47-$50{\mu}m$ in length including a slightly curved sperm nucleus (about $1.50{\mu}m$ in length), an acrosome (about $0.56{\mu}m$ in length) and tail flagellum (44-$48{\mu}m$ in length). In two species, the axoneme of the sperm tail flagellum of each species consists of nine pairs of microtubules at the periphery and a pair of cental doublets at the center. Therefore, the axoneme of the sperm tail flagellum shows a 9 + 2 structure. In particular, taxonomically important some charateristics of sperm morphologies of two species in the family Veneridae are acrosomal morphology of the sperm, The axial filament is not found in the acrosome as seen in a few species of the family Veneridae in the subclass Heterodonta. The acrosomal vesicle is composed of right, left basal rings and the apex part of the acrosomal vesicle. In particular, right and left basal rings show electron opaque part (region), while the apex part of the acrosomal vesicle shows electron lucent part (region). These charateristics belong to the subclass Heterodonta, unlikely a characteristic of the subclass Pteriomorphia showing all part of the acrosome being composed of electron opaque part (region). Therefore, it is easy to distinguish the families or the subclasses by the acrosomal structures. The number of mitochondria in the midpiece of the sperm of S. purpurata and M. petechialis in Veneridae are five. However, the number of mitochondria in the midpiece of the sperm in most species of Veneridae in the subclass Heterodonta are four. Therefore, the number of mitochondria of the sperm midpiece of two species are exceptionally 5, and it is only exceptional case in the species in Veneridae in the subclass Heterodonta. Except these cases, the number of mitochondria in the sperm midpiece in all families in the subclass Heterodontaare are 4, and now widely used in taxonomic analyses.

The purpose of this study was to determine the differences in internet use motivations and problem behaviors among vocational high school students according to internet addiction and family system type. Five hundred vocational high school students from Daegu took part in the survey. The questionnaire survey consisted of an internet addiction self-assessment scale, a family system type scale, an internet use motivation scale, and a problem behavior scale. The data was analysed using MANOVA and Cronbach a, and the $Scheff\acute{e}$ test was used for post-hoc analysis. The major findings of this study were as follows: First, the study found significant differences in adolescent internet use motivation according to internet addiction. Adolescents in the high dangerous user group showed higher communicative, experiential, and addictive motivations than adolescents in potentially dangerous and normal user groups. Also, there were no significant differences in informative motivation according to internet addiction. Regardless of internet addiction, adolescents tend to use the internet to search for information and to solve problems. Second, there were significant differences in adolescents' problem behaviors according to internet addiction. More specifically, adolescents who were in the high dangerous user group displayed more problem behaviors toward their body, family, school, and society than adolescents in the potentially dangerous and the normal user groups. Third, an adolescent's family system type significantly influenced his/her internet use motivation. Adolescents from an extreme family showed higher communicative and addictive motivations than adolescents from middle and balanced families. Fourth, there were significant differences in the problem behaviors of adolescents according to family system types. Adolescents from an extreme family showed more problem behaviors toward their body, family, school, and society than adolescents from middle and balanced families.

This study was inquire into the state of the family ethics during the period of the beginning of 1880′s to the 3.1 independence movement of 1919 which has been the black period in the history of Korean family ethics. The research was conducted by analyzing the newspapers, magazines, related literature and articles of the period. It was the beginning of the 1860′s and by the "Cheondo-Kyo" (the Religion of the Heavenly) way that the issues regarding the equality of sexes as the central concern of the modem family ethics came to be the object of the social discourse for the first time in Korean history. The social discourse had come to be positively activated around 1900, when the intellectuals of the "Korean enlightenment" had begun to the feel necessity of the modernization of Korean socialite and the importance of the women education as the essential part of it. However, the activation of the social discourse itself, especially with the newspapers of that period did not mean the changes of the traditional Confucian family ethics, but the discourse of the modernizing forces had become the seeds for changing the family ethics of the Korean people. The made chauvinistic nature of the family ethics of the period was not so much different from those of the preceeding patriarch societies, but the state of the family ethics during the period are characterized by several social phenomenon such as the rising needs of using the "Hangle"(Korean alphabet) instead of Chinese character for the equal education of the both sexes, increasing practices of the early marriage, customs of trade marriage in accordance with the demand of excessive weeding presents, and regarding social consciousness of the traditional family ethics as patriotics attitude against the Christian rejection of the ancestor worship ritual.
