본 연구는 우리나라 HRD관련 학회지의 내용분석(content analysis)을 통하여 인적자원개발의 동향과 주요 이슈를 제시함으로써 앞으로 우리나라 HRD 분야가 나아가야 하는 방향을 모색해 보는 것을 주요 목적으로 한다. 이를 위해 HRD 관련 핵심적인 학술단체라고 할 수 있는 한국산업교육학회, 한국기업교육학회, 한국인력개발학회에서 발행하고 있는 2006년부터 2011년까지의 학회지 논문 279편을 분석 대상으로 하였다. 분석틀은 연구주제, HRD 프로세스, 연구방법, 연구자 소속기관에 대한 조사로 하였으며 연구결과는 다음과 같다. 첫째, 연구주제로서는 교육훈련에 대한 주제가 가장 많이 논의 되었으며 조직변화와 개발, 경력개발, 국가 및 지역인적자원개발 등의 주제들은 상대적으로 연구자들의 관심이 적었던 것으로 나타났다. 둘째, HRD 프로세스 부분에서는 분석, 설계 및 개발, 실행, 평가 중 ‘분석’의 영역에 압도적으로 많은 논문들이 생산된 것으로 나타났다. 셋째, 연구방법 측면에서는 이론적 연구와 양적 연구의 빈도수가 가장 많아 질적 연구와 실천적 연구의 확대가 필요한 것으로 지적되었다. 넷째, 연구자 소속기관에 대한 조사는 대부분 대학의 연구자들이 학회지 논문의 상당한 부분을 차지하며, 수도권 중심인 것으로 나타나 HRD 연구의 구조적 한계에 대한 성찰이 필요한 것으로 나타났다. 본 논문은 이러한 연구결과를 바탕으로 HRD 분야의 이슈와 향후 발전을 위한 방향성 및 제안점들을 결론적으로 제시하였다. This study aims to shed light on the direction for developing the field of HRD in Korea by presenting major trends and issues of HRD through the content analysis of Korean HRD journal articles. For this purpose, the researchers analysed total 279 articles for a 6 year period (2006 - 2011) of academic journals produced from three main HRD related academic societies which are The Korean Society for Training and Development, The Korean Association of Human Resource Development, and The Korean Society for Learning and Performance. The analysis framework for the study was composed of four elements, which were research themes, HRD process, research methodology, and institutions that the authors of the journal articles belong to. The major findings of this study were as follows: 1) the themes related to training and development were more frequently discussed than the issues with organization change and development or career development; 2) as the dimension of HRD process, the most articles heavily focused on ``analysis`` rather than intervention, implementation, or evaluation; 3) the HRD researchers much depended on utilizing quantitative research methodology compared to qualitative research methodology or practical developmental research which received less attention; 4) the researchers in the articles were mostly affiliated to universities of capital area. As a conclusion, the study recommends the future directions for the development of the field of HRD in Korea based on the above study results.

감 꽃은 과실을 맺는 암꽃과 꽃가루를 내는 수꽃, 암술과 수술을 모두 가진 양성화가 있다. 관행 교배육종법으로 부본용 수꽃 신품종을 육성한다면 최종 선발까지 15년 정도의 장기간과 넓은 시험포장이 요구된다. 유묘기에 수꽃 착생 개체를 조기에 선발하여 육종효율을 증진하고자 꽃의 성표현을 알고 있는 주요 품종 88개체를 대상으로 Akagi 등(2014)이 보고한 수꽃 선발 마커들의 적용 효과를 검증하였다. OGI locus marker와 DISx-AF4S marker 적용 결과 각각 83품종, 72품종에서 꽃의 성표현과 분석 결과가 일치하였다. 육성품종인 ‘미감조생’을 모본으로한 교배조합 등으로부터 나온 실생 2,509개체에 OGI locus marker 수꽃 선발 마커를 적용하여 890개체를 선발하였고, 분석 완료한 교배실생 중 아직 착과가 되지 않았거나 고사한 개체를 제외한 1,186개체를 대상으로 꽃의 성 표현과 마커 분석 결과를 비교하였을 때 401개체가 불일치한 것을 확인하였다(33.8%). 다양한 교배조합으로부터 나온 실생 889개체에 DISx-AF4S marker를 적용하여 분석한 결과 636개체를 선발하였다. 분석 완료한 교배실생 중 아직 착과가 되지 않았거나 고사한 개체를 제외한 379개체를 대상으로 꽃의 성 표현과 마커 분석 결과를 비교하였고 247개체가 불일치한 것을 확인하였다(65.2%). 이상의 결과들을 종합하여 볼 때, 검토한 DISx-AF4S, OGI locus marker는 육종현장에서 활용하기에 유용하지 않을 것으로 판단된다. Persimmon flowers are fruit-bearing female, pollen-bearing male, or hermaphrodite, containing both a pistil and a stamen. Using prominent PCNA persimmons as male parents is very important for breeding programs, as the selection procedure for new cultivars bearing male flowers requires a long time and a large field in a traditional crossbreeding method. To improve breeding efficiency through early selection of male flower-bearing plants at the seedling stage, analysis was performed on 88 major cultivars whose gender expressions are known, using two male flower selection markers recommended by Akagi et al. The OGI locus marker and DISx-AF4S marker results showed that 83 and 72 cultivars, respectively, matched in terms of gender expression and marker analysis. For the OGI locus marker, 890 plants were selected from 2,509 seedlings obtained from crossbreeding with the mother plant “Migamjosang,” which was the breeding cultivar. Comparing the gender expression of the flowers and the marker with 1,186 crossbred seedlings, excluding the unfertilized and dead plants, inconsistencies were found in 401 plants (33.8%). For the DISx-AF4S marker, 636 plants were selected from 889 seedlings obtained from 12 cross-combinations. The results of the sex expression and marker analysis were compared to 379 plants, excluding the unfertilized and dead plants, and inconsistencies were found in 247 plants (65.2%). These results indicate that the examined DISx-AF4S and OGI locus markers would not be suitable for utilization in the breeding field.

Air temperature in Korea has increased by 1.5oC over the last 100 years, which is nearly twice the global average rate during the same period. Moreover, it is projected that such change in temperature will continue in the 21st century. The objective of this study was to evaluate the potential impacts of future climate change on the rice production and adaptation methods in Korea. Climate data for the baseline (1971~2000) and the three future climate (2011~2040, 2041~2070, and 2071~2100) at fifty six sites in South Korea under IPCC SRES A1B scenario were used as the input to the rice crop model ORYZA2000. Six experimental schemes were carried out to evaluate the combined effects of climatic warming, CO2 fertilization, and cropping season on rice production. We found that the average production in 2071~2100 would decrease by 23%, 27%, and 29% for early, middle, and middle-late rice maturing type, respectively, when cropping seasons were fixed. In contrast, predicted yield reduction was ~0%, 6%, and 7%, for early, middle, and middle-late rice maturing type, respectively, when cropping seasons were changed. Analysis of variation suggested that climatic warming, CO2 fertilization, cropping season, and rice maturing type contributed 60, 10, 12, and 2% of rice yield, respectively. In addition, regression analysis suggested 14~46 and 53~86% of variations in rice yield were explained by grain number and filled grain ratio, respectively, when cropping season was fixed. On the other hand, 46~78 and 22~53% of variations were explained respectively with changing cropping season. It was projected that sterility caused by high temperature would have no effect on rice yield. As a result, rice yield reduction in the future climate in Korea would resulted from low filled grain ratio due to high growing temperature during grain-filling period because the CO2 fertilization was insufficient to negate the negative effect of climatic warming. However, adjusting cropping seasons to future climate change may alleviate the rice production reduction by minimizing negative effect of climatic warming without altering positive effect of CO2 fertilization, which improves weather condition during the grain-filling period.

This study was carried out for breeding of direct seeding cultuvars. In direct seeding cultivation, low temperature germination rate is very important character for stable emerge of early seedlings. In this study low temperature germination rate(LTGR) were tested using 89 rice cultivars breeded from 1994 to 2008 year. The results are summarized as follows. Rice cultivars were breeded after 2004 year LTGR was higher than before 2003 year breeded cultivars. In med-late maturity cultivars LTGR was slightly higher than early or medium maturity cultivars, but there was no significance. Premium quality or high quality cultivars showed more high LTGR than superyield or stability cultivars. The LTGR of rice cultivars breeded in Iksan(NICS department of rice and winter cereal crops) were higher than other institutes breeded cultivars.

The objective of this short communication is to introduce several evaluation methods to crop model users because the evaluation of crop model performance is an important step to develop or select crop model. In this paper, mean error, mean absolute error, index of agreement, root mean square error, efficiency of model, accuracy factor and bias factor were explained and compared in terms of dimension and observed number. Efficiency of model and index of agreement are dimensionless and independent of number of observation. Relative root mean square, accuracy factor and bias factor are dimensionless and not independent of number of observation. Mean error and mean absolute error are affected by dimension and number of observation.
