  • Purpose: This study was conducted to identify the perceptions toward school forest programs related to forest welfare services in elementary schools and suggest strategies to activate new programs. Methods: A mixed method research was performed. Four teachers and one forest therapist participated in a focus group interview; 162 teachers answered a survey. Results: The teachers were aware of the effects of the forest program, but there were some barriers, including the question of whether there was an accessible forest, school forest management problems, the risk of teachers' work overload, and the lack of program diversification for elementary students. Solutions included the expansion of school forests and forest facilities available to students, development of a variety of programs, provision of appropriate information on available facilities, and cooperation with educational institutions for institutionalization and increased effectiveness of school-based forest utilization programs. In addition, a scientific basis for data accumulation is needed. Conclusion: The Ministry of Forestry is cooperating with the Ministry of Education and local education offices to activate a forest-use health promotion program for elementary school students. Additionally, to utilize the forests in regular education courses, teachers should strive to spread positive awareness of forests.

  • 본(本) 연구(硏究)는 산림경영협업체(山林經營協業體)의 산림작업(山林作業)을 담당하기 위하여 1984년(年)부터 협업경영지도소별(協業經營指導所別)로 조직된 산림경영협업체작업단(山林經營協業體作業團)의 문제점과 앞으로의 과제를 밝히고자 수행하였다. 울산군(蔚山郡) 4개(個) 산림경영협업체작업단(山林經營協業體作業團) 단원(團員) 33명(名)과 진안군(鎭安郡) 1개(個) 산림경영협업체작업단(山林經營協業體作業團) 단원(團員) 10명(名)을 대상으로 1993년(年) 7월(月)과 8월(月) 사이에 직접 설문에 의한 조사를 실시 분석하였다. 그 결과, 충분한 산림작업량(山林作業量)을 확보하지 못하여 거의 활동하고 있지 않는 작업단(作業團)이 존재하고 있었으며, 그 때문에 임업기술교육(林業技術敎育)을 받은 작업단원(作業團員)의 전직(轉職)이 많아, 숙련(熟練)에 의한 효율적(效率的)인 산림작업(山林作業)이 저해되고 있는 실정이었다. 정부(政府)는 전업적노동자(專業的勞動者) 중심의 작업단(作業團) 육성에 중점을 두고 있으나, 작업단(作業團) 육성에는 지역의 노동력시장(勞動力市場), 농임업구조(農林業構造), 노동력구성(勞動力構成), 임금수준(賃金水準), 산림작업량등(山林作業量等)이 고려되어져야 한다는 결과를 얻을 수 있었다.

  • In this paper we have introduced some results of study on stand growth pattern and stand structure of larch forest which are located in selected forest sites of Khangai and Gobi-Altai mountain ranges of Mongolia. Our investigations showed that growth intensity and stand structure in western Mongolia are very specific from the other forest vegetation zones of Mongolia. Studies on the stand structure and growth trend indicate that tree types of stand structure and different types of growth of Larix sibrica are very common in Western Mongolia. These peculiarities of stand structure and growth of larch stands in Western Monolia could be used for inventory work and an improvement of the forest management in Western Mongolian region. The larch tree is the dominant tree species in Western Mogolia. Forest cover of the region is about 15%, which is two times higher than the country's average. In this region forest area is divided into 4 forest sub-regions: the Central Khangai, Western Khangai, North Eastern Khangai and South Easterun Khangai sub-regions including taiga, pseudo taiga, sub taiga, sub-alpine and forest steppe belts. Silviculture practices and forest research management request to study forest growth trends in local and general conditions, which means to indicate a change of taxonomic characteristics of stand from time to time including diameter, height, basal area, growth stock etc. The forest management practice mostly uses tables of forest growth and yield based on the results of long term research on forest growth. Forest yield tables and other relevant forest standards of Russia are used for the forest inventory and forest management. They are not able to determine forest structure and growth peculiatities of Mongolian forests. Studies on forest resource assessment in Mongolia indicate that after logging operations and forest fires the natural regeneration of desired species such as pine and larch often does not succeed. This situation forces to take a different approach of forest management and silviculture practice depending on the stand structure and growth rate of the forest stands. According to our investigation in last years, forest growth pattern of larch forest depends mostly on stand structure, stand age and growth condition including forest soil, climate and location in different slopes. Due to improve environmental function of forest ecosystem in the region, it is needed to conduct very comprehensive study of high mountain forest ecosystem in selected sub-regions.

  • The plant Empetrum nigrum, valued in the traditional system of medicine, is well known for its antibacterial, antifungal, and antioxidant properties. In the present work, the effect of removal of shoot apical meristem (SAM) on shoot proliferation was studied. It was observed that removal of SAM promoted shoot proliferation whereas intact tip resulted in higher survival percentage. Further, the effect of different concentrations of BA on above was also studied. During root formation the effect of light quality after treatment with IBA was investigated. For rooting, continuous red light without IBA resulted in maximum rooting percentage. The above factors when taken into consideration during micropropagation of this endangered plant can result in healthier plantlets. The results show that the species could be successfully conserved by in vitro propagation system.

  • The effect of storage temperature and the storage period of hardy kiwifruits on the fruit firmness, soluble solids and fruit weight were studied in this work. The investigation was carried out on the Sae-Han cultivar of Actinidia arguta. It has an edible smooth skin and contains high amounts of sugar and vitamin C (ascorbic acid). In this research, the measurement of fruit firmness, soluble solids, and fruit weight were carried out at various temperatures (5, 10, 15, and 20℃) during 14 days. Fruit firmness rapidly decreased and soluble solids content increased at 15 and 20℃. We also investigated the correlation between fruit firmness and soluble solids content. There was a strong correlation between fruit firmness and soluble solids content. That means that fruit firmness affect the soluble solids content of hardy kiwifruit.

  • We scrutinized the Korean taxonomic literature, with special focus on some nomenclatural points and four different cases were listed categorically. Several naked names (nomen nudum), invalidly published names, typographical and orthographical errors, incorrect use of hybrid names and authorship, and errors in the citation of the bibliographic references have appeared in newly published literature in Korea, due to misapplications of ICBN (International Code of Botanical Nomenclature). Although literature review and synonyms are imperative and essential elements of taxonomic study, many author citations tend to be copied from one publication to another without any confirmation of the original source. It is strongly recommended that scientists who have previously published careless work should be more careful, and they should be instructed to read original descriptions and to learn current practices in the code.
