This paper aimed to verify the current status of adolescents' donations and predictors influencing their donation behaviors. First, the result revealed that adolescents' donations were higher in the order of time, material, and talent donation. Second, donation motives, attitude towards donation, self-esteem, a sense of community, and trust in charitable organization were positively correlated. Third, the predictors of material donation behaviors of adolescents were gender, age, extrinsic motives, attitude towards donation, sense of community, and trust in charitable organization. And the predictors of time donation behaviors were gender and sense of community, and those of talent donation were age, intrinsic motives and sense of community. The strategies for the activation of adolescents' donations were suggested.

This research, as a study on individual donators' relationship durability with donated organizations, is carried out with the variables of individual donators' empirical satisfaction, sense of unity, familiarity, relationship quality, donation will, and loyalty. This research, based on the interrelationship among the variables effecting on donation activities, makes a relationship durability will model between donators and donated organizations through the examination of the existing studies on donation activities, and suggests the marketing points to increase the relationship of non-profit organizations based on the model. This paper examined 242 material or time donators for non-profit organizations in Seoul and Kyeonggi-Do province and proved 11 hyperses. The result shows that the donation will and loyalty for donated organizations are influenced by the relationship quality. In addition, the relationship quality of reliability and immersion seems to be influenced by the empirical satisfaction and the familiarity with donated organizations. Therefore, donated organizations need to make efforts to increase the donators' satisfaction, and to increase the familiarity between donators and donated organizations. In other words, they should increase donators' satisfaction with active promotions and they should do marketing activities to increase donators' familiarity.

Giving behavior promotes social solidarity and lessens social deprivations by voluntary practices to make better communities. Despite the increasing trend of giving in terms of participation and amount in Korean society, the giving culture has deeply rooted in charitable emotion based on compassion, still far from social solidarity. This paper attempts to identify giving behavior by investigating its characteristics and changes in its motives from the compassion-based social welfare to social responsibility and community solidarity, centering around 'Yellow envelope campaign' started in 2014 to support the living expenses and cost of litigation for the fired workers of Ssangyong Motors. By employing questionnaire survey and in-depth interview, it analyzes the horizontal relationships, reciprocal responsibility, social capital, and pursuit for conflict solution. Even though the campaign didn't change our society as a whole, but it cast the social questions on the birth of social empathy and solidarity.

동양달팽이(Nesiohelix samarangae)의 자성생식기 중 정자낭(spermatheca)의 미세구조를 투과전자현미경을 이용하여 관찰하였다. 성체의 정자낭의 내강에서는 정자와 이와 관련된 물질들 또는 상피로부터의 분비물질들이 관찰되었다. 정자낭의 내강을 둘러싸고 있는 벽의 상피는 단층원주상피로서 내강과 연한 세포의 원형질막은 미세융모를 가지고 있었으며 섬모는 가지고 있지 않았다. 이 미세융모들의 기부에서는 고배율 하에서 pinocytotic vesicle들이 관찰되었고 때로 세포의 분비물을 세포 밖으로 방출하는 모습도 관찰되었다. 세포들의 상부세포질에는 많은 수의 mitochondria가 있었고, 때로 분비과립과 lysosomd들이 존재하기도 하였다. 이들보다 아래에는 잘 발달한 골지체와 과립소포체(RER)들이 있었다. 이 부위에서 분비과립들이 많이 형성되어 있는 모습이 세포에 따라 관찰되었고, 그 아래에 즉, 각 세포의 하반부 세포질에 상하로 긴 핵이 관찰되었다. 세포의 기부 원형질막은 상부 세포질 내로 깊게 그리고 수없이 많이 주름을 이루고 있어 인접한 세포와의 경계를 구분할 수 없을 정도였다. 기저막의 아래에는 근육다발과 색소세포들이 결합조직 내에서 관찰되었고, 정자낭의 외막은 큰 액포로 인하여 세포질들이 원형질막 주변으로 밀려나 있는 특이한 세포들로 이루어져 있었다. 정자낭의 기능은 정자를 일시 저장하며 정자낭 상피에서 분비되는 소화액들로 정자를 일차적으로 세포외 소화하고 소화되지 않은 물질들을 흡수하여 이차적으로 세포내소화하는 것으로 생각된다.

The purpose of this study was to explore the levels of ethical consumptions and related variables on ethics of adolescents as consumers. This subjects were 552 middle and high school students. The research results are summarized as follows. 1. The scores to measure ethical consumptions level of the adolescents was ranged from 2.87 to 3.08, which were relatively low. 2. The ethical consumptions(fair-trade product consumption, donation and giving, local consumption and eco-friendly consumption) in demographic variables were found to have significant differences depending on their religion, perceived social class, father's education and mother's education. 3. The result of hierarchical regression analysis indicated that consumer education experience, the eco-friendly values, materialism, saving, experiencing mass media on affecting the fair-trade product consumption. The major variables affecting the ethical consumptions in the donation and giving were materialism, consumer education experience, experiencing mass media and the eco-friendly values. The significant variables affecting the local consumption were the eco-friendly values, consumer education experience, materialism, experiencing mass media and saving. The major variables affecting the eco-friendly consumption were the eco-friendly values materialism.

연안과 천해의 저질은 그 상층 해수의 변화에 영향을 받으며, 또한 반대로 상층의 수질을 변화시키기도 한다. 저질은 지질학적 기원을 갖는 기부위에 상층의 물에서 가라앉는 부유현탁물질과 수중생물의 배설물, 생물의 사체 등의 유기질이 층을 이루면서 형성된다. 저질은 화학적, 생물적 변화나 물의 유동에 의한 영향을 받지만 변화속도가 비교적 작고, 상층 수질의 변화 결과를 누적적으로 받기 때문에 수질변화의 평균적 이력(履歷)을 간직하며, 수역의 오염의 진행경향이나 그 속도에 대해서 수질만으로는 알 수 없는 장기간의 영향에 대한 적산적(積算的)관점에서의 정보를 보유하고 있다. 이 조사해역은 굴을 비롯한 패류 양식장이 밀집분포하고 있는 해역이며, 진해만에서 수하식 양식장의 분포비중이 가장 큰 해역으로서 양식의 역사도 30년이 넘는다. 이 해역은 외해와의 해수교류가 원활하지 못하여 양식생물의 배설물과 양식장의 탈락물이 이 육지로부터 유입되는 오염부하물질과 더불어 그대로 해저에 퇴적되고 있는 곳이라고 할 수 있다. 이 연구는 양식장 저질의 유기오염의 수준을 평가하여 양식장 및 연안해역의 관리를 위한 자료로 제공하고자 하였다.

Vas deferens is a long tube and could be divided into four regions as its morphological characters: a short and slender proximal region, a convoluted region, a straight and more thick distal region, and an ejaculatory duct, It is connected with the posterior outer horns of the testis and runs to the gonopores opened on the coxa of the fifth walking legs, The proximal region consists almost entirely of simple cuboidal epithelial cells, $12\~28{\mu}$m in height, surrounded by a thin basal membrane. A small aggregation of high cuboidal epithelium is obsened from one side of the proximal region. The convoluted and distal region is composed of two kinds of epithelial cells; high cuboidal epithelial cells, $40\~120{\mu}m$ in height located in dorsal portion and simple cuboidal epithelial cells of $12\~28{\mu}$m in height located in ventral and lateral portion. The ejaculatory duct is surrounded with two kinds of muscle layers, inner longitudinal and outer circular muscle fibers, The lumen is lined with high and simple cuboidal epithelium in almost equal proportions. The proximal region contains mature sperm and basophilic substances. The eosinophilic substances appeared newly going toward the convoluted region and are laid along simple cuboidal epithelial cell layer. Tube-like content (spermatophore) of the vas deferens is ejaculated from a pair of genital pores at mating. Two masses of the content fuse together side by side and are usually deposited on the female thorax between the second and fourth or fifth pereiopods, The spermatophore formed measures $2.7\~4.0$ mm in length and $1.5\~2.7$ mm in width.

Three fertilization envelopes (FE) have been observed after the artificial insemination of U. unicinctus oocytes. The substances of the first fertilization envelope, which is an effective barrier against excessive sperm, come mainly from the surface coat of the oocyte. The secretions of the cortical granules take part in formation of the 2nd fertilization envelope. Histologically, the 3rd fertilization envelope is not amorphous as seen under light microscope, but contains numerous panicles under electron microscope, which would be contributed to harden the envelope by 60 min after the fertilization. With the substantial similarity between the 1st fertilization envelope and the surface coat of the oocyte, and the coincidence of retraction of microvilli and the formation of the 1st fertilization envelope, it is suggested that the microvilli contain the sperm receptors in U. unicinctus. Some granular substances from the distal part of the acrosome diffuse on the surface coat of the oocyte while the acrosomal tubules penetrate into the surface coat. The acrosomal tubules arise from the proximal part of the acrosome and pass through the acrosomal lumen.
