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.

Centered on Kathleen Kye, a designer who conveyed messages on social issues through her dresses, and established her own identity, this study aimed to examine what theme, method of expression and inner meaning her 'statement' had, as a way of expressing a critical awareness. After reviewing discussions by Duggan G. G. as well as dictionary definitions, statement fashion design can be defined as a work or fashion shows containing a message of a designer who is free from a particular trend or consumerism in various social issues. Statement fashion designers give opposing messages on social issues through their fashion collections. As a result, research shows that contemporary statement fashion designers are expressing themes of a fashion systems, fetishism, body image, collision, environment, as well as the socially disadvantaged by appropriation, reuse, slogan, metaphorical pattern and performance. Satire, awakening, challenge and support can be derived from the inner meaning of contemporary statement fashion design. In terms of the theme, method of expression and inner meaning, this study showed that KYE collection of the designer Kathleen Kye expresses critical awareness on the modern society. Research findings reveal that KYE collection include the following themes: long-term youth unemployment, conflict collision in war or on the Internet, fetishism by youth in a get-rich-quick fever, environmental issue causing destruction of an ecosystem by decrease in bee population, school violence and the socially disadvantaged related to alienated immigrants. Also, as a method of expression themes, such as metaphorical patterns, were used. The patterns used images including a skeleton, gun, heart, rope, plaster, homeless box, bee, honeycomb, chain and a slot machine. On the other hand, the inner meaning of statement in KYE collection showed satire on social issues, awakening on social issues unrecognized by the masses, and support for the socially disadvantaged.

The indiscriminate use of the fossil fuel has caused serious environmental pollutions such as the shortage of energy and global warming. Microalgae have being emphasized as $3^{rd}$ generation biomass which makes the carbon dioxide reduce effectively as well as produces the biofuel. Large scale production of microbial biomass by continuous culture is a quite challenging issue, because off-line optimization strategies of a microbial process utilizing a model-based scheme give rise to many difficult problems. In this paper, the static and simple control method which was able to be applied in time-variant growth environment and large scale of algae culture was studied. The significant disturbances in on-line measurement of cell density were reduced by Savitzky-Golay FIR smoothing filter. Dunaliella salina was cultivated continuously in a flat panel photobioreactor by the on-off control of the turbidostat process.

Coral reefs are among the most dynamic and various ecosystems on tropical ecosystem. They provide a large number of important ecosystem services. Despite their importance, they appear to be one of the most susceptible marine ecosystems. Dramatic decreasing of coral reefs has been reported from every part of the world. Indonesia contains 18% of coral reefs of world's total. Unfortunately the status of coral reefs in Indonesia is already in critical and poor condition. Coral reefs communities in Indonesia are subjected to a variety of environmental disturbance. Threats to Indonesia's coral reefs resources can be divided into two main types: anthropogenic and natural disturbances. The major anthropogenic disturbances on coral reefs in Indonesia are destructive fishing, pollution, coastal development, mining and harvesting live fish and coral, tourism. The natural disturbances such as cyclones, volcanic eruptions, earthquakes, tsunami and predator also contribute to coral reefs destruction in Indonesia. In my paper I tried to compare between natural and anthropogenic disturbances on coral reefs in Indonesia and raised these questions: (i) how the natural disturbances differ from anthropogenic area (ii) which type of disturbances has caused the greatest impact on coral reef ecosystem. My finding is that both of anthropogenic and natural disturbances give major impact on coral reefs in Indonesia. The important issue here is coral reef resilience could be disturbed by synergistic effects between various anthropogenic and natural disturbances. This phenomenon has significant conservation and management implication. The appropriate management should be conducted to protect coral reefs ecosystem in Indonesia. Mangrove management will succeed only when local people are involved and get sustainable benefits from mangrove ecosystem. Community based management and Integrated Coastal Zone Management (ICZM) are type of management that can be applied on coral reef ecosystems in Indonesia.

Recently, the construction of the small Al alloy ships is an increasing trend in viewpoint such as the disposal issue of a retired ship, the enhancement of environmental regulation and resources recycling etc. for FRP ships. However, Al alloy ship which can achieve high speed by light weight in marine environment is exposed to a problem on materials damage by cavitation-erosion which is generated by large impact pressure with the collapse of air bubbles due to cavitation. Consequently, in this study, water cavitation peening technology was applied in Al alloy for ship to enhance durability life by preventing cavitation damage. So, the water cavitaton peening application time that presented the excellent cavitation characteristic investigated. The weight-loss of 5456-H116, 5083-H321 and 5052-O Al alloy at the optimum water cavitation peening time were improved to 42.11 %, 50.0 % and 25.7 %, respectively.

Adenocarcinoma of esophagus (AE) is a complex disease, affected by a variety of genetic and environmental factors. Much evidence has shown that the MutY glycosylase homologue (MUTYH) plays a key role in the pathogenesis of many cancers. However, there have been no reports on influence on AE in the Han Chinese population. The objective of this study was to investigate this issue. A gene-based association study was conducted using three single nucleotide polymorphisms(SNPs) reported in previous studies. The three SNPs (rs3219463, rs3219472, rs3219489) were genotyped in 207 unrelated AE patients and 249 healthy controls in a case-control study using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). The results revealed that the genotype distribution of rs3219472 differed between the case and control groups (OR=1.66,95%CI=1.11-2.48, P=0.012), indicating that an association may exist between MUTYH and AE. These findings support a signifcant role for MUTYH in AE pathogenesis in the Han Chinese population.

It is recent trend that every countries are opening their border in the name of liberalization of contemporary era. Shipping is not exceptional and it used to be said as international business. Therefore, co-operation and openness of maritime sectors between regional countries is required to utilize resources that each countries can manage. It can be done by employing their vessels in other countries' short sea area. However, there are some problems to implement this practices, here cabotage is centre of issue. Each countries do not open their sea in order to protect their national interests in sovereignty. But, it should be opened if co-operation between each countries work well and properly. To achieve true maritime co-operation, countries as Korea, China and Japan in Northeast Asia region should have understanding for the opening of cabotage. In order to make things work well, it can be done by the lessons from EU and American cases. Therefore, it should be clarified such as market scale to provide cabotage trade, employment as well as interested parties, and technical safety matters as well as environmental standards. Then cabotage matters can be smoothly resolved between three countries in Northeast Asia region.

As recent traffic policy focuses on reduction of congestion and environmental contamination, with a catch phrase, 'Green Traffic', Low Carbon Green Growth' and 'Sustainable Development', introducing the new eco-friendly transport means including railway has been emerging as critical issue. Included in the new transport means are BRT, Bimodal Tram and LRT, and this study was intended to evaluate and analyze Bimodal, among others, which generates less emission, noise and vibration thanks to hybrid type traction system employed by Bimodal Tram, which is considered a future-oriented system because of eco-friendly features and cost efficiency as well as punctuality and convenient accessibility to bus. Thus in this study, appropriateness of Bimodal Tram comparing to other system(BRT) was suggested, using conversion traffic from the road, traffic speed and CO2 emission at the metropolitan area and large provincial areas as the barometer in evaluation, and furthermore, the measures applicable to introduction strategy that will meet various functional aspects in urban area in the coming days were developed.

The purpose of this study was to establish objectives for ninth grade studies of heredity and evolution in middle school in an attempt to foster students' consciousness of bioethics, and it's additionally intended to develop and apply lesson plans handling different points at issue and to determine the effects of the lesson plans on the bioethics of middle school students. The subjects in this study were 152 ninth graders in a middle school, whose science scores were similar. An experimental group and a control group were made up of 76 students respectively, and a pretest was conducted with test paper developed by this researcher to assess their awareness of bioethics. The experimental group took lessons by using the teaching plans prepared in this study, and the control group received typical education according to the curriculum. And then a posttest was implemented with test paper developed in this study to compare the two groups. In addition their science grades were compared as well. The findings of the study were as follows: First, seven learning objectives were selected from three units related to bioethics in the third-year 8th category of heredity and evolution of middle school. Second, in order to attain the selected learning objectives, four session lesson plans were prepared. Third, the experimental group that studied using by the lesson plans made better progress in bioethics awareness and the gap between the two was statistically significant(t=6.61, p<.001). The former were ahead of the latter in consciousness about species equity(t=7.71, p<.001), the dignity of life (t=3.78, p<.001), human rights(t=2.99, p<.01) and equity among generations(t=2.66, p<.01), but not in awareness of the diversity of species. Fourth, there was no significant gap in science scores between the students studied according to the curriculum and those who received instructions by using the lesson plans developed in the study.

Reducing carbon dioxide ($CO_2$) exhaust has become a major issue for society in the last few years, especially since the initial release of the Kyoto Protocol in 1997 that strictly limited the emissions of greenhouse gas for each country. One of the primary sectors affecting the levels of atmospheric greenhouse gases is agriculture where $CO_2$ is not only consumed by plants but also produced from various types of soil and agricultural ecosystems including greenhouses. In greenhouse cultivation, $CO_2$ concentration plays an essential role in the photosynthesis process of crops. Optimum control of greenhouse $CO_2$ enrichment based on accurate monitoring of the added $CO_2$ can improve profitability through efficient crop production and reduce environmental impact, compared to traditional management practices. In this study, a sensor-based control system that could estimate the required $CO_2$ concentration considering emission from soil for cucumber greenhouses was developed and evaluated. The relative profitability index (RPI) was defined by the ratio of growth rate to supplied $CO_2$. RPI for a greenhouse controlled at lower set point of $CO_2$ concentration (500 ${\mu}mol{\cdot}mol^{-1}$) was greater than that of greenhouse at higher set point (800 ${\mu}mol{\cdot}mol^{-1}$). Evaluation tests to optimize $CO_2$ enrichment concluded that the developed control system would be applicable not only to minimize over-exhaust of $CO_2$ but also to maintain the crop profitability.
