Classification of the cycle of seminiferous epithelia into 12 stages by the morphological changes in acrosomal system and evaluation of the relative frequency of stages and the cell association were histologically performed in the mature Korean native Jin-do dogs. The results were summarized as follows; 1. The minimum number of type A spermatogonia averaged 1.01 at stages I, while maximum number averaged 2.47 at stages XII. Some type A spermatogonia divided at stage XII to produce the type intermediate(IN) spermatogonia at the following stage I. The type IN spermatogonia divided at stage IV to produce the type B spermatogonia at stage V. 2. The type B spermatogonia divided at stage VI to produce the preleptotene primary spermatocytes at stage VII. The secondary spermatocytes observed at stage XII. The secondary spermatocytes observed at stage XII divided to give rise to the round spermatids at the following stage I. The numbers of the first spermatocytes and spermatids were almost constant, respectively, through all the cycles of seminiferous epithelium. 3. The acrosomal vesicle was invaginated to occupy one third to half of spermatid nucleus at the cap phase, which was different from that of rodent and ruminant spermatid nuclei. 4. The relative frequencies of stages I to XII of seminiferous epithelia cycle were 10.34, 4.84, 5.03, 8.22, 10.86, 6.63, 6.42, 18.88, 10.17, 6.18, 7.62% and 4.81%, respectively.

In order to study on the Sertoli cell, we attempt have been made to measure the average number of each germ cells per Sertoli cell on the 12 stages of cycle in matured korean Jindo dog. The fine structure of Sertoli cell junctional specialization was studied with electron microscope. The results were summarized as follows; 1. The average number of various germ cells associated with Sertoli cell was 9.77 to 13. 80 through stages of cycle and the total average number was 11.62. 2. Sertoli-Sertoli cell junctional specialization was present in seminiferous epilthelium, and Sertoli-spermatid cell junctional specialization rose from stage 8 spermatid, persisted to step 13 spermatid and then disappeared. The structure of Sedoli-spermatid cell juncticnal specialization was not similar to that of Sertoli cxlls. 3. Just after spermiation, free-surface of Sertoli-spermatid cell junctional specialization was replaced by Sertoli cell cytoplasm with tubulobulbar complex at the neiglaboring region observed. 4. The Sertoli cell process was located within the cytoplasm of late stage spermatids. Some membranes of residual body and spermatid cytoplasm partly disappeared, resulting in opening of the cytoplasm of spermatid into that Sertoli cell. This fact suggested that spermatid cytoplasm was partly eliminated.

진도견 정세관의 정세포와 Sertoli 세포내 glycogen의 분포

In an effort to obtain basic data of carbohydrate metabolism during spermiogenesis of the sexually-matured Jindo dog, the glycogen distribution in the testis was investigated by light and transmission electron microscopy. Periodic acid thiocarbohydrazide silver proteinate physical development(PA-TCH-SP-PD) staining method provided better results in the detection of glycogen granules from Sertoli cells and germ cells than the periodic acid schiff(PAS) staining method did. Pre-treatment of the tissue sections with ${\alpha}$-amylase elicited a significant decrease in PA-TCH-SP-PD stained granules, which suggested that the stained granules were of glycogen origin. High concentration of the glycogen granules were observed in the Sertoli cells, especially in its column, sheet-like processes, club-like processes, and tubular processes. The glycogen granules were unevenly distributed in some Sertoli cell columns. These results strongly indicated that the Sertoli cells of Jindo dogs showed vigorous activity of carbohydrate metabolism.

진도견 정자형성계 세포들의 Lectin-binding patterns

박영석,이성호,Park, Young-seok,Lee, Seong-ho 대한수의학회 1996 大韓獸醫學會誌 Vol.36 No.3

The lectin-binding patterns in the testis of the sexually matured Jindo dog were investigated to study the distribution of glycoconjugates in the seminiferous tubule under light and transmission electron microscopy. Positive reactions to Wheat germ agglutinin(WGA) and Dolichos biflorus agglutinin (DBA) were observed in the Sertoli cell and in the residual body of spermatid with a stronger reaction in the Sertoli cell to the lectins than in the residual body. Strong reactions to Soybean agglutinin(SBA) and Peanut agglutinin(PNA) were observed in the acrosome vesicles of the Golgi- and cap-phase spermatid, while a moderate reaction was observed in the acrosome-phase, maturation-phase spermatid and the residual body. The acrosome area of the spermatid reacted intensively to Griffonia simplicifolia agglutinin( GS-I) when the cell was in the acrosome-phase and maturation-phase, and the same reaction to the GS-I was observed in the residual body. However, the seminiferous tubule did not react to Ulex europeus agglutinin I(UEA-I). The gold-labelling of the Sertoli cells with DBA resulted in positive reactions of the Sertoli cell column and processes when observed under the electron microscopy, while the Golgi-, cap- and acrosome-phase spermatids reacted positively to SBA in the peripheral low-dense area of the acrosome vesicle of spermatid. Based on these results, we concluded that differences in the lectin-binding pattern of the seminiferous tubules were recognized in the Jindo dog compared to other animals.

박영석(Park, Young-seok),양희옥(Yang, Heeok) 한국문화산업학회 2015 문화산업연구 Vol.15 No.2

본 연구는 항공사를 이용하는 한국, 미국, 일본 고객들을 대상으로 항공사의 서비스 가치와 만족도, 행위의도 간의 영향관계에 대하여 알아보는 것을 목적으로 하였다. 서비스 산업의 대표적인 분야인 항공 산업은 저가 항공사의 적극적인 마케팅과 시장 점유율 확대, 지속되는 세계적인 경기침체 등으로 그 어느 때 보다도 더욱 심화되고 있는 경쟁 속에서 항공 기업들은 이제 고급화 및 특화된 서비스 제공 외에도 고객에게 가치를 주고 만족도를 제고하여 고객유지를 확보하는 서비스 전략을 간구해야 한다. 본 연구는 선행연구를 바탕으로 항공사 이용고객에 있어 서비스 가치와 고객만족이라는 핵심 변수와 행위의도와의 영향관계를 구성하여 연구모형을 설계하였고 이에 따라 수집한 자료를 분석한 결과를 요약하면 다음과 같다. 서비스 가치는 고객만족에 영향을 미치는 것으로 나타났다. 오늘날 고객이 느끼는 가치가 마케팅 전략에서 대두되고 있는 요소임을 파악할 수 있었다. 그리고 만족도 또한 행위의도에 매우 긍정적인 영향을 미치고 있음을 알 수 있었다. 그리고 한국, 미국, 일본 국가 간의 서비스 가치와 고객만족, 행위의도에 미치는 영향력 차이를 비교 분석하였다. 검정결과는 서비스 가치가 고객만족에 미치는 영향력은 한국, 미국, 일본 세 국가 간에 통계적으로 유의한 차이가 없는 것으로 나타났다. 그러나 고객만족이 행위의도에 미치는 영향은 국가 간에 차이가 있는 것으로 나타났는데 한국의 경우에는 고객만족이 행위의도에 미치는 영향이 미국이나 일본과 비교하여 상당히 큰 것으로 나타났다. The purpose of this study was to find out the influential relationship among service value, satisfaction and behavioral intention of airlines passengers. Based on previous studies, hypothesis assuming positive influential relationship among service value, customer satisfaction and behavioral intention were created and the empirical research was performed accordingly to investigate the influence among those variables. Written questionnaires were handed out to 500 customers who had air-travel experience within a year. Survey data was collected from August 1st to August 30th, 2012 from Incheon International Airport and 3 multinational company in Korea, Japan and the United States with convenient and judgemental samplingmethods. Atotal of 409 data was used for analysis with the SPSS and LISREL statistical software packages. Results of this study are follows. Findings of this study indicated that service value had an positive influential relationship for the customer satisfaction. Customer satisfaction was also strongly linked to customer"s behavioral intentions. Satisfied customers tend to re-patronize the airline generating positive word of mouth and recommendation. Additional analysis was made to find out the differences of the influential relationship of service value, customer satisfaction and behavioral intention among Korean, American and Japanese passengers. No significant differences were found for the influential relationship between service value and customer satisfaction. However Korean passengers showed the significant higher influential relationship between customer satisfaction and behavioral intention thanAmerican and Japanese passengers. 본 연구는 항공사를 이용하는 한국, 미국, 일본 고객들을 대상으로 항공사의 서비스 가치와 만족도, 행위의도 간의 영향관계에 대하여 알아보는 것을 목적으로 하였다. 서비스 산업의 대표적인 분야인 항공 산업은 저가 항공사의 적극적인 마케팅과 시장 점유율 확대, 지속되는 세계적인 경기침체 등으로 그 어느 때 보다도 더욱 심화되고 있는 경쟁 속에서 항공 기업들은 이제 고급화 및 특화된 서비스 제공 외에도 고객에게 가치를 주고 만족도를 제고하여 고객유지를 확보하는 서비스 전략을 간구해야 한다. 본 연구는 선행연구를 바탕으로 항공사 이용고객에 있어 서비스 가치와 고객만족이라는 핵심 변수와 행위의도와의 영향관계를 구성하여 연구모형을 설계하였고 이에 따라 수집한 자료를 분석한 결과를 요약하면 다음과 같다. 서비스 가치는 고객만족에 영향을 미치는 것으로 나타났다. 오늘날 고객이 느끼는 가치가 마케팅 전략에서 대두되고 있는 요소임을 파악할 수 있었다. 그리고 만족도 또한 행위의도에 매우 긍정적인 영향을 미치고 있음을 알 수 있었다. 그리고 한국, 미국, 일본 국가 간의 서비스 가치와 고객만족, 행위의도에 미치는 영향력 차이를 비교 분석하였다. 검정결과는 서비스 가치가 고객만족에 미치는 영향력은 한국, 미국, 일본 세 국가 간에 통계적으로 유의한 차이가 없는 것으로 나타났다. 그러나 고객만족이 행위의도에 미치는 영향은 국가 간에 차이가 있는 것으로 나타났는데 한국의 경우에는 고객만족이 행위의도에 미치는 영향이 미국이나 일본과 비교하여 상당히 큰 것으로 나타났다.
