This study was carried out to develop the breeding and/or cultivation materials by investigating characteristics of natural habitats of Allium monanthum in South Korea. Natural habitats of sunny, half-shady, and shady conditions were 13 (10.7%), 66 (54.6%), and 42 (34.7%), respectively. Natural habitats were located around upland (45.4%), around Buddhist temple area (28.1%), on mountain area (18.2%), along roadside (2.5%), and along riverside (5.8%), respectively. Natural habitats ranged widely in all areas of Korea by $33^{\circ}N{\sim}38^{\circ}N$ and $126^{\circ}E{\sim}129^{\circ}E$. In Chungbuk and Gyeongbuk natural habitats were more than in Jeonbuk and Jeonnam. Distribute pattern were formed densely. Sprout stage was from September till March of next year. Grew from March to April, and there was no plant formed flower stalk in natural habitats.

In this paper, the author gave a brief review on the meaning and background involving the growth of chemical ecology. Semichemicals which might be developed as insect control techniques incorporating in IPM program were described. The relevant semichemicals were grouped under separate topics including intraspecific semiochemicals, or pheromones (sex pheromones, alarm pheromones, and epidiectic pheromones), and interspecific semiochemicals, or allelochemics (allomones of Plant origin, and kairomones favoring natural enemies). Here, the author dealt with those of practical aspects only. The prospects of chemical ecology in insect pest management were also proposed.

The purpose of this study was to identify the natural habitat of Bulbophyllum inconspicuum Maxim. in Hongdo, Jeonnam Province, South Korea. A field investi gation was conducted between May 2019 and May 2021. The growth of B. inconspicuum species was confirmed in three known regions based on National Survey on the Distribution of Endangered Species. Additionally, in the area investigated, 37 new regions harboring B. inconspicuum were detected. The newly observed B. inconspicuum grew naturally on Quercus mongolica, Rhaphiolepis indica var. umbellata, Carpinus turczaninowii, and rocks. Most of them were found on southeast and southwest slopes with altitude above 250 m. As few as 10 up to hundreds of B. inconspicuum were found in clusters. Close to their habitat, Calanthe sieboldii Decne. ex Regel, C. aristulifera Rchb. f. and C. × kibanakirishima Maek. were also found. As Hongdo is an island, multiple endangered species were found together. Thus, once the habitat of a certain plant is discovered, it is very likely that illegal collection of several other species will also occur. Proactive internal and external measures are needed to preserve these species.

The integration and management of various national ecological assessments are essential for the benefit of the public. In the Republic of Korea, the Ecological and Natural Map (ENM) serves as a comprehensive platform that synthesizes the results of national ecosystem surveys into a unified system interface. To provide the current status and characteristics of our policy, we analyzed the ENMs and related appeals from 2014 to 2022. Following their implementation, the ENM Guidelines underwent nine revisions, with most of the revisions pertaining to appeals. Nine public announcements were made regarding the ENM, resulting in a gradual expansion of the conservation area. The data also showed a consistent increasing trend in appeals. Most of the 1st-grade areas in the ENM regions where appeals were filed have significantly decreased. The larger area or the smaller population density of an administrative distinct, the more appeals were filed. Our study presents information regarding the current status of the ENM system. The analysis of the operational direction and indicator trends across the 16-year period since the establishment of the system provides valuable insights for similar systems.

This study was carried out to develop the breeding and cultivation of Allium grayi by investigating its natural habitats in Korea. The number of sunny, half-shady, and shady natural habitats were 194 (64.0%), 96 (31.7%), and 13 (4.3%), respectively. Natural habitats included upland (51.2%), Buddhist temple (18.8%), mountain (11.6%), roadside (7.9%), river (5.9%), paddy field (2.3%), and seashore (2.3%). Natural habitats ranged widely in all areas between $33^{\circ}N{\sim}38^{\circ}N$ and $126^{\circ}E{\sim}130^{\circ}E$. Self-generation patterns included growing spontaneously with a 1~10m distance between plants, and there were 3~5 bulbils around each bulb. The sprout stage began in September and continued until March of next year in natural habitats. The bolting period was May, with the following three patterns: tuber (59.2%), flower and tuber (24.7%), and flower (16.1%).

The purpose of this study was to investigate and offer useful information on natural dyeing underwear industry through an analysis of 20's purchasing behavior and design preference between male and female. From 600 questionnaires that were distributed, 512 with usable data were coded for further statistical analysis including descriptive statistics(frequency and chi-square test), by using SPSS 12.0 and the major results were as follows. Given that a large number of 20's purchase men's underwear by their parents, and women's of their own. It was found that the underwear for men in their 20's should be developed in an attempt to place greater emphasis on improving functions as an outerwear. It is important to strengthen the design and marketing strategy specially tailored to 20's of natural dyeing underwear products.

The sicence of ecology was introduced into Korea as a part of biology translated into Chinese or Korean from western biology textbooks imported by way of China or directly from the West at the end of 19th c. to the beginning of 20th c. After the Japanese annexation of Korea in 1910, Japanese technologists had studied applied ecology to exploit the natural resources of Korea. Reforestation, begetation eclogy, riparian vegetation, etc. were investigated by workers from the West. Such ecological researches, however, did not contribute to the introduction of ecology into Korea, and the anture of the Korean peninsula was utilized by foreign ecologists as ecological research sites. Several Korean ecologists, not many, worked actively at the end of Japanese rule, and contributed to the settlement ecology in Korea since 1945.

Two unrecorded fungi, Diaporthe perseae and Fusarium falciforme, were isolated from soil sampled from Dokdo in Korea. There have been many reports of Diaporthe sp. and Fusarium sp. in mainland Korea but none of them have reported in Dokdo so far. We used the morphological features and two molecular markers including the internal transcribed spacer and translation elongation factor 1-α region to compare and analyze these species with the closely related taxa. As a result, we confirmed that these fungi were unrecorded soil fungi in Korea. Then, the cultural and morphological characteristics such as the conidia of these two fungal species could be clarified. These results are expected to help us to understand the distribution of fungi in Dokdo and manage the Dokdo Island Natural Reserve.

The North Korean laws on natural environments, land and infrastructure were comprehensively analyzed in order to help establish the legal system to solve problems of ecosystem and land management in North Korea. The citizen's environmental rights in North Korean Constitutional Law emphasize the aspect of conservation of the natural environments. The laws on the managements of natural environments and land are relatively integrated in North Korea. In the management of natural environments, ecosystem conservation is centered on designation of natural protected areas. Priority for infrastructure construction is emphasized in land management. The economic and technical support is needed to build advanced legal systems for the conservation of natural environments and ecological land management and to improve their performance of law enforcement.

Anti-oxidative and anti-inflammatory activities of Cotoneaster horizontalis Decne ethanol extract (CHEE) were evaluated. CHEE possessed a potent scavenging activity against 1,1-diphenyl-2-picryl hydrazyl, which was similar to the activity of ascorbic acid which was used as a positive control. CHEE also effectively suppressed hydrogen peroxide-induced reactive oxygen species on RAW 264.7 cells. Furthermore, CHEE induced the expression of the anti-oxidative enzyme heme oxygenase 1, and its upstream transcription factor, nuclear factor-E2-related factor 2. CHEE inhibited LPS induced nitric oxide (NO) formation as a consequence of inducible NO synthase (iNOS) down regulation. Taken together, these results provide us with an important new insight; that C. horizontalis possesses anti-oxidative and anti-inflammatory activities. Therefore, C. horizontalis may be utilized as a promising material in the field of nutraceuticals.
