Two distinct spider communities were studied in the crowns and ground surfaces of pine plantations at Mt. Ungilsan, Kyonggi-do using pitfall traps and knock-down by spraying of an insecticide (D.D.V.P.) to sample spiders. There were 34 species of 11 families in the ground community and 41 species of 15 families in the crown community, with only 9 species being collected in both. Wandering spiders comprised 78.5% of the crown community and 90.8% of the ground community. Guild abundance and the most abundant families were distinctly different in the two habitats: agile hunters (Salticidae:32.4%) and nocturnal hunters (Clubionidae:19%) in the crown, runners (Lycocidae:32.8%) and nocturnal hunters (Gnaphosidae:31.2%) in the ground. Dominant species were Clubiona jucunda (Karsch) and Mymarachne japonica (Karsch) in the crown, while in the ground they were Pardosa laura Karsch and Gnaphosa silvicola. Species diversity(H ) had peaks in May, July and November in the ground community, while in the crown community peaks were in June and September. The seasonal trends of species diversity (H ) were due mainly to differences in the number of species and the numbers of individuals collected at each sample date rather than to differences in equitability among species. Spier guilds and dominant species have different seasonal patterns based on the temporal differences in prey availability in the two communities and the reduction of temporal overlap.

During the past 4 years, I have made a careful analysis of the present rotating system of hunting areas, on the one hand, by asking a group of hunters to fill out a questionnaire, and on the other hand, by referring to the written documents on the subject. And, as a result, it is concluded that this system, by varying the hunting grounds each year, contains in itself several problems as follows. 1. The hunters find it quite inconvenient to use a different hunting ground year after year and they also complain that the present hunting ground charge is more than it is worth. Therefore, it is expected that the number of hunters will explosively increase in the future with the betterment of hunting conditions. 2. The hunters have almost no information about game and they are, as a whole, lacking in the ethics of hunting. 3. The allotment of time in hunting training courses is not so sufficient that it is next to impossible to improve the quality of hunters. 4. As a rule, the population density of wildlife is so sparse that it falls short of the proper standard of it. 5. The present hunting system does not seem to contribute to the advancement of tourism. 6. It is absolutely necessary to make a general survey of the situation of wildlife for the legal protection of it. Besides, the interests of hunters are so closely tied up with those of farmers and foresters that dreastic measures should be taken to settle their conflicting differences. For the purpose of solving the above-mentioned problems and at the same time, of developing sound hunting practices in the long run, I hereby make two suggestions. 1. The Establishment of the Hunting License Test System It is desirable to issue a license to a prospective hunter after he has met a special qualification and then passed a test so that he may have bits of information needed for his hunting activities. 2. The Introduction of The Revier System The fundamental concept of this system is based on the assumption that the private landowner should reserve a right to the pursuit of game and take responsibility for wildlife management.

This study was conducted to do a comparative analysis of hunting system in 16 OECD(Organization for Economic Co-operation and Development) countries. Hunting is one of the most advanced types for developing natural resources, esp. wildlife, which is one of major products from forest. There are two types of hunting system ; Revier and/or License System, around most countries which have traditional advanced hunting and higher hunter population. Licence system, which is chosen in Korea, is less efficient ways of hunting for maximizing economical value and wildlife management than Revier system does. Adopting better system for much more efficient economical condition from hunting in Korea in a future is a ultimate goal in this study. The first step for the goal is an analysis of these two system among 16 OECD countries ; United State, Japan, Germany, France, etc. Comparative researches in hunting regulations such as number of hunters, hunter ratio to population, hunting bags, game species, seasons, ammunition and hunting permit are a next step for adopting developed hunting system in Korea. Korea has a smallest hunter ratio to population (1/2,463) among 16 OECD centuries and economical value lead by hunting is estimated still very low. Revier system is a popular one in most OECD countries except United State, Japan, etc, which is useful for wildlife management and maximizing economical value of hunting. And usually rifles are permitted for big game hunting. Hunting examination and/or insurance are compulsory for achieving hunting permit. Depend on game species, yearly hunting bag and season are constructed in most OECD countries.

In this study, we attempted to assess the efficacy of a method to improve the quality of prepared bread via the addition Poria cocos powder to wheat flour at a range of concentrations from $0{\sim}5%$. The approximate composition for Poria cocos powder was as follow: moisture 7.67%, crude protein 0.61%, crude fat 0.58%, crude ash 0.32%, and crude fiber 0.30%, when using the flour to which the Poria cocos powder had been added, specific volume, falling number, and dough yield values all increased with increasing concentrations of added Poria cocos powder. The result of our microscopic observations revealed a relative scarcity of larger starch granules, and the bread prepared with the Poria cocos powder evidenced a sparse structure. With regard to the Hunters color value measurements, the L value decreased with increasing concentrations of Poria cocos powder. but the a and b values evidenced an inverse relationship with the concentration of added powder. The texture, hardness, and adhesiveness characteristics of the bread decreased with increasing concentration of added Poria cocos powder. but the gumminess and chewiness of the bread increased. However, we noted no significant differences in the springiness and cohesiveness characteristics among the experimental groups assessed herein. In the sensory evaluation, the quality of the 2% or 3% Poria cocos powder breads was optimal in terms of its taste and flavor.

A faunistic study on the spiders (Arachnida: Araneae) from Mt. Jumbong Kangwon-do was carried out from 1996 to 1999. During the survey period, 144 species of 88 genera belonging to 27 families including 5 undetermined species were identified from 900 collecting individuals. The dominant families were Linyphiidae 21 species; 14.6% of total species), Araneidae (20 species, 13.9%), Theridiidae (16 species, 11.1%), and Salticidae 12 species, 8.3%). The composition of the species of web builders was richer than that of hunters. As for species commonness with adjacent countries, the numbers of common species between Mt. Jumbong and Japan, Mt. Jumbong and China, and Mt. Jumbong and Russia were 15 species (80.4%), 98 species (68.5%), and 48 species (33.6%), respectively. The number of common species among these four regions were 39 species (27.3%). So, the spider species composition in Mt. Jumbong seemed being much similar to those in neighbor countries. An outline of biogeographical distribution of spiders can be summarized as 1 Cosmopolitan species (0.7%), 16 Palearctic species (11.2%), 7 Holarctic species (4.9%), 25 Korean endemic species (17.4%) and no Oriental species. In the spider fauna at Mt. Jumbong, therefore, there are high level of occurrence of Korean endemic species with northern spiders as Palearctic and Holarctic species. The level and direction of man-made development may have negative effect on regional biota.
