호텔종사원의 역할갈등과 모호성이 근로의욕 및 직무태도 간의 관계

손재근,이정은 동북아관광학회 2016 동북아관광연구 Vol.12 No.2

본 연구는 호텔종사원의 역할갈등과 역할모호성이 근로의욕과 직무태도간의 관계를확인하여 그 시사점을 제시하고자 하였다. 가설검증결과는 역할갈등과 근로의욕간의관계는 역할간의 갈등요인만이 근로의욕에 유의한 영향관계가 나타나고 있으며 역할모호성은 근로의욕에 영향관계가 나타나고 있었다. 근로의욕은 직무만족에 대하여 유의한 영향관계가 형성되고 있었고 근로의욕은 직무몰입에 유의한 관계가 형성되고 있었다. 역할갈등과 직무만족간의 관계에 있어는 개인역할갈등 요인만이 직무만족에 유의한 영향관계가 형성되었고 개인역할갈등과 전달자간의 갈등이 직무몰입에 영향관계가 형성되고 있었다. 마지막으로 역할모호성과 직무몰입간의 관계에서 유의한 관계가형성되었다. 가설검증에 대한 그 시사점을 제시하여 경영매뉴얼과 조직의 풍토 등의역할이 중요함을 확인하였다. The purpose of this study was to determine the relationship between the role conflict of the hotel employees and the role ambiguity attitudes and work desire was to present the implications. Role conflict is the relationship between hypothesis testing results and work desire has appeared a significant impact on the relationship between work motivation million Role of conflict role ambiguity factors were related effects appear to work desire. Work motivation has had a significant effect relationships are formed for job satisfaction work desire was formed a significant relationship to job involvement. Role conflict and job satisfaction in the relationship between the individual's role conflict is the only factor to job satisfaction significant effect relationship is established between the sender and the role conflict was personal conflict job involvement in the formation and effect relationship was active. Finally, a significant relationship was formed on the relationship between role ambiguity and job commitment. It presented its implications for hypotheses were confirmed by the important role of management and organization of the manual climate.

Catering Service의 합리적운영에 관한 연구

손재근,구태회 한국관광정보학회 2000 觀光情報硏究 Vol.- No.5

For the modern people who have the preference of futuristic rural homes there will come a time when they will prefer catering services from small house parties to wedding ceremonies to stay away from the complicated traffic problems and to also save time. Plus the hotel culture will alter along with this trend. Customers have been having baby showers, birthday parties and wedding parties outside of their homes in restaurants instead of having them in their apartments. However, when the rural home cultures set in, this party culture will move in back to the homes like a fad. This trend will reappear for it is normal for people to change their way of thinking and if there are more and more people living in houses with front yards the catering services will automatically change to services that can be used any time at any place. The quality of catering services must develop not because of this trend but because customers are partial to having parties with themes in special place they prefer, desiring to have party cultures of their own. For better improved catering services there ought to be quality training programs to cultivate qualified man power with improved equipment such as lighter and stronger chairs and tables with more sophisticated design and color. Plus there should more diversified events according to the theme of the party. In other words, the catering service should be professional for a more systematic service preparation. Also the managers' interest and participation to improve the problems should be promoted especially for an effective management of the employees and services. Now for the Korea tourist culture of the 21st century the company's culture of the hotels must change. With a more competitive service, the catering service management should advance.

孫再根,李壽寬,吳秉根,朴來敬 韓國作物學會 1984 한국작물학회지 Vol.29 No.4

벼 약배양을 통하여 분화된 식물체의 배수성분포와 반수체식물의 효과적인 염색체배가시험을 실시하여 얻어진 결과를 요약하면 다음과 같다. 1. 15조합의 F1 을 재료로 하여 약배양한 결과 얻어진 574 식물체의 배수성분포는 반수체가 49.7%, 2배체는 48.6%, 다배체는 1.7%로 나타났다. 2. 통일형조합(Japonica/Indica)에서는 반수체(60.6%)가 많은 경향이었고, 일본형조합(Japonica/Japonica)에서는 2배체(54.8%)가 많은 경향이었다. 3. 2,4 -D, NAA가 첨가된 배지에서는 반수체가, Kinetin이 첨가된 배지에서는 2배체가 많은 경향이었다. 4. 반수체의 분얼경 분주에 의한 염색체자연배가율은 개체에 따라 0~25%로 나타났고 평균 8.2%였다. 5. Colchicine 0.1% 용액의 잎집주사접종법에 의한 염색체배가율은 0~33.3%의 변이를 보였으며 평균 18.8%로 나타났다. 6. 약배양에서 유래된 식물체의 배수성에 따른 형태적인 차이는 반수체가 2배체에 비하여 간장이 64.6%, 수장이 63.4%, 지엽장은 68%, 지엽폭은74.4%로 뚜렷한 차이를 나타내었다. Variation in ploidy level of regenerated plants from rice anthers and effective diploidization methods of haploid plants were studied to obtain basic information in rice breeding through anther culture. In a total of 574 plants derived from anther culture using 14F1 hybrids as materials, there were 49.7% haploids, 48.6% diploids and 1.7% polyploids, respectively. The frequency of haploids in Japonica/Indica crosses was 60.6%, and that of Japonica/Japonica crosses was 43.0% in average. Inclusion of 2.4-D or NAA as phytohormone may increase the frequency of haploids, but kinetin may increase the frequency of diploids. The rate of auto-diploidization by tiller separation of haploid plants showed 8.2% in average. The rate of diploidization by leaf-sheath injection of colchicine showed 18.8% in average. Morphological characters of haploids plants showed that 64.6% in culm length, 63.4% in panicle length, 68% in flag leaf length, and 74.4% in flag leaf width compared to diploid plants. These apparent morphological differences will contribute to identify the ploidy of plants derived from rice anther culture.

손재근,김광수,김경민 한국식물생명공학회 1994 식물생명공학회지 Vol.21 No.4

약배양에서 형성된 배를 GA$_3$가 첨가되지 많은 MS배지에 배양한 결과 발아률이 12.5%로 낮았으나, 0.3 mg/L GA$_3$가 첨가된 배지에서는 81.3%의 높은 발아률을 보였고 발아후의 생육양상도 양호하였다. 자엽출연기의 배를 GA$_3$ (0.3mg/L)가 첨가된 MS배지에서 20일 동안 전배양한 후 IAA, cytokinin 및 GA$_3$가 단용 또는 혼용된 배지에 배양한 바 배의 발아률은 모든 처리에서 72% 이상의 높은 발아률을 보였으나 발아후의 생육면에서는 2.0mg/의 BA 단용 또는0.1 mg/L의 kinetin과 0.3 mg/L의 G가 혼용된 배지에서 가장 좋았다. 0.5 mg/L GA$_3$가 첨가된 배지에 자엽출현기의 배를 이식하여 4$^{\circ}C$에 8주동안 저온처리하면서 저온처리 기간별 배의 발아률 및 발아후의 생육양상을 조사한 바 저온처리기간이 길어질수록 작약의 발아률이 향상되어 8주동안 저온처리된 배에서 73.3%의 가장 높은 발아률을 나타내었고 발아후의 생육양상도 가장 양호하였다. 작약의 체배양에서 재분화된 식물체의 배수성을 조사한 바 분화식물체 개체 중 반수체와 이배체가 각각 낙.8%와 31.2%로 가장 많았고, 4배체5.2%)와 3배체(1.3%)도 있었으며 염색체수가 4개(1.3%) 또는 6개(5.2%)인 이수체 있었다. Pollen-derived embryos cultured on the hormone-free medium showed a low germination frequency (12.5%) and poor growth response after germination. The greatest frequency of germination (81.3%) was obtained from the embryos cultured on medium with 0.3mg/L GA$_3$.The greatest frequency of generation (81.3) was obtained from embryos cultured on medium with 0.3mg/L GA$_3$. The embryos precultured for 20 days on medium with 0.3mg/L GA$_3$were transferred to the medium with various combination of hormones such as IAA, kinetin, zeatin, 6-benzylaminopurin (BA) and Gh$_3$. The germination frequency of cotyledonary stage embryos showed above 72% on media with all of the hormonal combinations, but the embryos germinated on medium with 2mg/L BA or 0.1mg/L kinetin and 0.3mg/L GA$_3$ developed more vigorously into plantlets than those of other hormonal combinations. Torpedo-stage embryos cultured on medium with 0.3 mg/L Gh$_3$ were pretreated for 8 weeks at 2-week intervals at 4$^{\circ}C$, The germination frequency of the cold-preheated embryos increased with the increment of pretreatment period from 2 to 8 weeks. The greatest frequency of germination (73.3%) was obtained from the embryos pretreated for 8 weeks at 4$^{\circ}C$. The chromosomes of the root-tip cells of W plane grown for 40 days after germination were observed. Most of the regenerated plants were haploid (55.8%) or diploid (315%), but triploid (1.3%), tetraploid (5.2%), or aneuploid (6.5%) were also detected among them.

벼 품종별 오존 피해 저항성 차이

孫再根,李相哲 韓國作物學會 1997 Korean journal of crop science Vol.42 No.3

벼 품종의 오존 저항성 판단을 위한 시험에서 오존의 처리농도는 0.3 ppm이 0.1 ppm보다 뚜렷한 결과를 보였고, 처리시간은 2∼4시간이 알맞은 것으로 나타났다. 묘대일수에 따른 저항성 정도는 파종후 3주까지는 생육이 진전될수록 높아지는 경향이었으나 3∼5주간에는 큰 차이가 없었다. 인디카와 통일형 품종들이 자포니카 품종보다 저항성이 높은 경향이었고, 자포니카 품종 중에서 장안벼외 7 품종은 높은 저항성을 나타내었다. 벼의 생육시기에 따른 피해엽율은 간척벼는 유묘기에서 밀양 2003외 4 품종은 최고 분열기에서 가장 높게 나타났고 임실율은 수잉기 처리에서 가장 낮았다. The response of seventy-five rice cultivars to ozone (O3 ) were tested in the open-top chamber with ozone producing and monitoring system to determine the varietal difference of resistance to O3 stress. Ozone was produced by electrostatic discharge in oxygen and was monitored by UV absorption ozone analyzer. Difference in response of rice to ozone was more clearly appeared on rice plants treated for 2 to 4 hours at 0.3 ppm concentration of O3 . Varietal resistance of rice to ozone was more distinctly classified at 21- to 35-day seedlings compared with 14-day rice plants. Most of indica and Tongil(indica~times japonica) type rice cultivars were more resistant than that of japonica cultivars based on the leaf injury to O3 . Eight Korean cultivars belong to japonica groups showed highly resistant reaction to O3 . Ozone exposure during booting stage caused lower grain fertility than exposures during seedling, maximum tillering and heading stages of rice.
