This study is tried to investigate and analyze the changing history of Korean forest management policy and revitalization alternatives of the private forest management. Korean forest management policy could be divided by two group periods, one is the forestry policy age through afforestation and reforestation, the other is the forestry policy age through forest management. Recently, the revitalization policy for the private forest management was evaluated through the result analysis of the 4th forest basic planning age for 10 years that is gone from 1998 to 2007, but it is not sufficient for the private forest management revitalization, and has still some fundamental problems. Therefore, this study is aimed to present various kinds of plans for the private forest management revitalization during the 5th forest basic planning age that has begun since the beginning of 2008.

Brucellosis is the most important bacterial disease of livestock in Bangladesh. The present study was conducted to determine the seroprevalence of brucellosis in goat and sheep in Mymensingh and Bogra districts of Bangladesh using slow agglutination test and Rose Bengal test as screening test and indirect enzyme linked immunosorbent assay as confirmatory test. Questionnaire based data on age, gender, area, client's complaint, number of animals in herds, disease history, reproductive problems such as abnormal uterine discharge, abortion or previous abortion in sheep and goat and their reproductive diseases were recorded. A total of 200 sera samples were collected from 80 sheep and 120 goats. The prevalence of brucellosis in goat was 2.50% and 1.25% in sheep. Positive reactors were only detected in female of both goat and sheep. In this study, there existed a significant association among abortion and the prevalence of brucellosis (p < 0.01). The prevalence of brucellosis in sheep and goat in Bangladesh is not negligible, and it is therefore worth considering the adoption of preventive measures.

The National Forest Inventory (NFI) is important for providing fundamental data for basic forest planning and the establishment of forest policies for the purpose of implementing sustainable forest management. The purpose of this study is to present the development of Korea's NFI including legal basis, sampling design, and measured variables and to review the usage of NFI data. The survey methods and forestry statistics among the Unites States, Canada, Japan, China, and European countries were briefly compared. Total 140 publications utilizing NFI data between 2008 and 2015 were categorized with 15 subjects. Korea has conducted the NFI 6 times since 1971, but only the $6^{th}$ NFI is comparable with the fifth, the previous NFI, because the permanent sampling plots have been shared between the periods. The Korean Forestry Statistics contains only half as many variables as that of advanced countries in Forestry. More researches were needed to improve consistent measurement of diverse variables through implementation of advanced technologies. Additional data for Forest Health Monitoring since the NFI $6^{th}$ must be under quality control which will be an essential part of the inventories for providing the chronological change of forest health.

Rates of molecular evolution are known to vary widely among taxonomic groups. A number of studies, examining various taxonomic groups, have indicated that body size is negatively and clutch size is positively correlated with the rates of nucleotide substitutions among vertebrate species. Generally, either smaller body mass or larger clutch size is associated with shorter generation times and higher metabolic rates. However, this generality is subject to ongoing debate, and large-scale comparative studies of species below the Order level are lacking. In this study, phylogenetically independent methods were used to test for relationships between rates of the mitochondrial cytochrome b evolution and a range of life history traits, such as body mass and clutch size in the Order Galliformes. This analysis included data from 67 species of Galliformes birds and 2 outgroup species in Anseriformes. In contrast to previous studies, taxa were limited to within-Order level, not to Class or higher. I found no evidence to support an effect of life history traits on the rate of molecular evolution within the Galliformes. These results suggest that such relationship may be too weak to be observed in comparisons of closely related species or may not be a general pattern that is applicable to all nucleotide sequences or all taxonomic groups.

Covering an area of about 39 ha, Qingming Shanghe Park is located in the northwest of Kaifeng, formerly the capital of seven dynasties in China. It is intended to serve as a tourist attraction based on a painting 〃Qingming Festival at Riverside〃 by Zhang Zeduan of the Northern song Dynasty, which vividly illustrates a real life on the both sides of the Bian River as well as in the urban area, Kaifeng, in early Spring. The park is a collection of varied buildings such as shops, restaurants, tea-houses, theaters, and hotels in the North song style, with an introduction of the history of Kaifeng, this paper examines design philosophy and methodology of the park, and discusses the creative design of the first stage development known as known as The South Area of the park. Marked by the Rainbow Bridge and the City Gate, the South Area is divided into three parts, the rural, suburban, and urban parts which are organized according to the spatial order showed in the painting. The South Area proves to be very successful because of its amazing sense of history and interesting folk performance. Furthermore, the preliminary 9planning of the second stage development known as The North Area is presented with references to culture, history and customs. The North Area is proposed to include the Old Sports & Games Garden, the Exhibition Garden, and the Hot Spring Garden with an appearance of the imperial gardens in the Northern Song, integrated with participation of old sports and games, display of old science & technology achievements, and enjoyment of hot spring bath.

Usnea longissima has a long history of use as a traditional medicine. Several bioactive compounds, primarily belonging to the polyketide family, have been isolated from U. longissima. However, the genes for the biosynthesis of these compounds are yet to be identified. In the present study, three different types of non-reducing polyketide synthases (UlPKS2, UlPKS4, and UlPKS6) were identified from a cultured lichen-forming fungus of U. longissima. Phylogenetic analysis of product template domains showed that UlPKS2 and UlPKS4 belong to group IV, which includes the non-reducing polyketide synthases with an methyltransferase (MeT) domain that are involved in methylorcinol-based compound synthesis; UlPKS6 was found to belong to group I, which includes the non-reducing polyketide synthases that synthesize single aromatic ring polyketides, such as orsellinic acid. Reverse transcriptase-PCR analysis demonstrated that UlPKS2 and UlPKS4 were upregulated by sucrose; UlPKS6 was downregulated by asparagine, glycine, and alanine.

Whangchangkumpyo(黃腸禁標 : forbidden mark of whangchangmok pine tree cutting) is not only a historical forestry material but also a valuable physical proof supporting historical facts recorded in written documents. This study, using 6 whangchangkumpyo's which have been discovered so far, has investigated a comprehensive value of kumpyo(禁標). For this investigation, the location, sine, inscription, discovery of them and how they were reported have been compared with what is recorded in written documents. A comparative analysis of whangchangkumpyo and its investigation have enabled the author to identify the distribution of high quality pine trees, the political and economic significance of kumsan(禁山) and bongsan(封山) at the time, changes in geographical names over time, bits of tracks from old road network. Finally, it is suggested in this study that the recognition of the value of whangchangkumpyo should be more encouraged and the protection of it should be necessary.

This article presents an overview of the Native Customary Rights to forests and its role in protecting the future of native people of Sarawak, Malaysia. The native people have had a long history and strong relationship with their forests. Existing documents and studies have been critically reviewed and analyzed in order to elaborate the Native Customary Rights which are critical to the native people of this region. To have a better understanding on Native Customary Rights, it is important to answer three related questions: (i) Who is a native of Sarawak, (ii) What is 'custom', and (iii) What is the nature of 'rights'? The roles of Native Customary Rights for economic, political or social reasons, operate through informal rules embedded in the natives' customs and traditions. These rules have never been codified into formal laws because the adat system merely functions to manage the human relations which are tied to culture thus making it difficult to codify the culture into laws. It is evident that there are several issues underlying the development of Native Customary Rights: (i) Native Customary Rights are considered as inferiority to those of the State, (ii) the issue of over-shadowing of traditional laws by the colonial rule and the current statutory laws and, (iii) projects and land schemes involving the Native Land. It is understood that the challenges of promoting Native Customary Rights are daunting task; however, the constitutional laws need to carefully revise to provide a better future for the natives.
