This paper aims at overviewing Korean fisheries profile with a view on why Korean fisheries need marine ranching program as a new fisheries paradigm - a community-based co-management approach and drawing some policy implications from the advanced experience in fisheries. The aims of community-based co-management approach as a planned approach can be set out under the planning objectives of efficiency and equity. In this context Tongyeong marine ranching program is an important government-sponsored pilot enterprise. Experiences in the advanced fisheries such as Canadian Snow-Crab case suggest that in order to be successful for marine ranching be successful it is necessary that (i) there should be high-value species, (ii) property right should be established, (iii) there should be the reasonable number of participants involved, (iv) the participants and the government should be able to share resource enhancement/management/utilization responsibilities and associated fisheries management expenses. Among these, management cost sharing based on the practical partnership between fishing communities and government is of particular importance because the government must have a full responsibility for all ranching program expenditure unless revenues sufficient to guarantee reasonable income and to share management cost are generated from the ranching business.

In this paper, we examine what changes the next-generation wireless communication systems will experience in terms of the technologies, services, and networks and, based on that, we investigate how the inter-cell interference management should evolve in various aspects. We identify that the main driving forces of the future changes involve the data-centric services, new dynamic service scenarios, all-IP core access networks, new physical-layer technologies, and heavy upload traffic. We establish that in order to cope with the changes, the next-generation inter-cell interference management should evolve to 1) set the objective of providing a maximal data rate, 2) take the form of joint management of power allocation and user scheduling, 3) operate in a fully distributed manner, 4) handle the time-varying channel conditions in mobile environment, 5) deal with the changes in interference mechanism triggered by the new physical-layer technologies, and 6) increase the spectral efficiency while avoiding centralized coordination of resource allocation of the users in the uplink channel.

Purpose: The purpose of this study was to determine the incidence of unintentional-injury and to identify factors related to the high incidence of unintentional-injury in the community in order to provide useful data for the development of prevention and intervention programs aimed at reducing unintentional-injury incidence. Methods: This study utilized data obtained from cross-sectional national surveys conducted for the 2001 National Health and Nutrition Survey targeting 37,769 individuals aged between 0 and 99 years old, which was performed using a face-to-face interview method. Demographic characteristics, unintentional-injury experience, types of injury, and attributes of health behavior were included in the study instruments. Results: About 1.3% of the subjects had experienced unintentional injury that required hospitalization at least once during the past year. Age older than 40 years, male gender, lower education, lower income, and blue collar workers were all significantly and positively associated with increased risk of unintentional-injury. Among the health behavior variables, sleeping less than 6 hours, drunk driving, and binge drinking were significantly associated with unintentional injury, while traffic accidents and falls/slips constituted 80% of all unintentional injuries. Conclusion: Public health efforts to reduce unintentional injuries should target high-risk populations such as males, those with low income and education levels, and binge drinkers.

This paper presents an analysis of the Developmental Approaches in Science, Health and Technology (DASH) program, a K-6 curriculum developed by the Curriculum Research & Development Group (CRDG) at the University of Hawaii employing the curriculum analysis framework created by Posner. Using this framework the analyst found that the DASH design is based on the research on learning, teaching, and assessment now driving efforts to reform science education at the elementary level. DASH embraces the constructivist idea that learning is a personal and social process and the recapitulation model that new concepts are built out of theories previously learned. DASH provides an understandable, exciting, and memorable experience in the operations of science, health, and technology, and develops their capacity to use the skills and knowledge of science, health, and technology both in and outside school. A number of studies of DASH have examined its functionality, effectiveness of pedagogy and what students learn. The innovative nature of DASH necessitated a multidimensional assessment that included both quantitative and qualitative research techniques. Ongoing development of the DASH program in the research setting of a university laboratory school permits ever deeper connections with emerging curriculum theory and curriculum practice, and allows new linkages as ideas are tested in research classrooms.

Radial color gradient of disk galaxies has been a key tool for diagnosing the ages and metallicities of the stars and gas of these galaxies, and thus, the formation process of these disks. In many cases, observational data support the 'inside-out' picture of disk galaxy formation proposed by Larson (1976). In this scenario, gas within dark matter halos cools and accretes on to the outer disk while enhancing star formation in the disk. Recent discoveries of "extended ultra-viloet" (XUV) disks also show that majority of disk galaxy experience active star formation within out disks where gas surface density is quite low (Thilker et al. 2007; Gil de Paz et al. 2007). However, neither gas, nor stars stay put within galaxies. They rather migrate into bulges, disperse throughout galaxies, or flow into and out of galaxies via various mechanisms. There have been a few notable studies to investigate how radial star formation and metal abundance gradients vary across populations of disk galaxies systematically. However, the mechanisms driving gas transport are still poorly understood. Cross-matching various galaxy catalogs including KVAGC and UKIDSS, we are investigating if color gradients of late-type galaxies depend on their physical properties, especially on environmental properties. We will present the result from the pilot study on Karachentsev isolated galaxy catalog.

Generally, classifiers have been used as machines to crush raw materials and classify suitable particle sizes in all industrial fields, such as food, chemical, and mineral. However, the technique for classifying micron-sized particles between 5 and $20{\mu}m$ is inferior. In particular, numerous experiments and considerable experiences are required to predict the particle size, because the classifier particle size is determined according to the internal flow. However, it is quite difficult to set the driving conditions so that the desired particle size can be classified only by experience and experimentation. Therefore, this study proposes a method of predicting the average particle size by employing multiphase flow analysis and the Taguchi method; this method is subsequently verified.

Recently, the performance and function of electrical and electronic system in automotive vehicles is developing at a rapid rate with the advancement of IT technologies. Combined together with micro-controller and sensor technologies, the Vehicle Smart System (VSS) being developed to improve driver's convenience and comfort has been employed to a variety of applications. In addition to the convenience system, the Auto-parking Assistance System (AAS) that is now attracting a new attention has been already applied to some vehicles, but it is currently limited to luxury car models only. In this paper, we present a fuzzy controller that enables autonomous parking assistance without the AAS. The controller can perform the assistance with information provided from moving status, current position and steering angle as one is able to park a car based on his/her experience and knowledge for driving and parking. We have evaluated its performance of the proposed controller by simulation and tested the excellence of the controller by building a model vehicle embedded with the micro-controllers.

Building Information Modeling (BIM) and its different work streams, such as 4D planning (4D), are among the major drivers for change in the construction industry. The primary aim of this research is to create a holistic map of both the barriers and drivers affecting the industrial uptake of BIM and 4D through the use of an extensive literature review and a survey of contractors and consultants from the UK AEC (Architectural, Engineering and Construction) industry. This research demonstrates that while non-technical barriers such as the inefficiency in the evaluation of the business value of BIM and 4D; the shortage of experience within the workforce, and the lack of awareness by stakeholders are recognized by professionals as main barriers to BIM and 4D adoption, current research is still largely concerned with technical advancement of BIM and 4D technologies. A holistic map of the driving and restraining forces affecting BIM and 4D widespread adoption was provided. The tackling of the non-technical barriers identified will help bridge the gap between technology, end-users and their processes.

Pervasive augmented reality (AR) technology can be used to efficiently search for the required information regarding products in stores through text augmentation in an Internet of Things (IoT) environment. The evolution of context awareness and image processing technologies are the main driving forces that realize this type of AR service. One of the problems to be addressed in the service is that augmented objects are fixed and cannot be replaced efficiently in real time. To address this problem, a real-time mobile AR framework is proposed. In this framework, an optimal object to be augmented is selected based on object similarity comparison, and the augmented objects are efficiently managed using distributed metadata servers to adapt to the user requirements, in a given situation. To evaluate the feasibility of the proposed framework, a prototype system was implemented, and a qualitative evaluation based on questionnaires was conducted. The experimental results show that the proposed framework provides a better user experience than existing features in smartphones, and through fast AR service, the users are able to conveniently obtain additional information on products or objects.

The goal of this study is to find out correlation between Driver's Unsafe acts(errors and violations) and Personality types. The experiment was performed on 180 subjects, men and women between 20's and 60's having experience in driving for 6 months at least. Personality types of the subjects were classified by MBTI(Myers-Briggs Type Indicator) GS type and Driver's unsafe acts were measured by KDBQ(Korean Driver Behavior Questionnaire) based on Reason's DBQ(Driver Behavior Questionnaire). The result of experiment showed several facts about the relation. The first is that the drivers of P (Perceiving) type commit more violations and slips than drivers of J(Judging) type. The second is that in the comparison among attitude indexes(EP, EJ, IP, IJ) the drivers of EP(Extroversions - Perceiving) commit more violations than other type drivers. Finally, only men of P(Perceiving) type commits more violations than men of J(Judging). Based on these facts, it is possible to use Personality types as a device to prevent unsafe acts in various fields for driver selection and accident prevention training classified by Personality types etc.
