  • Prunus glandulosa Thunb. [=Cerasus glandulosa (Thunb.) Sokolov] (Rosaceae) is native to the warmtemperate region of China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hebei, Henan, Jiangsu, Shaanxi, Shandong, Sichuan, Yunnan, and Zhejiang Provinces). It is naturalized in the United States (i.e. Alabama, Michigan and North Carolina) and Canada (Ontario). This species, previously only recorded as introduced or cultivated plants on the Korean Peninsula, was confirmed to be naturally distributed in the southwestern coast islands(i.e. Geomun-do, Chuja-do and an uninhabited island in Shinan-gun of Jeollanam-do). Prunus glandulosa Thunb. is distinguished from a related taxon P. japonica var. nakaii (H. Lév.) Rehder by pedicel 8-12 (-16) mm long, linear stipules, glabrous style, and pink petals. The morphological characters and illustration of P. glandulosa Thunb. are provided with line drawings and photographs from the natural habitat. In addition, it is likely that a new habitat will be found by plant biodiversity investigations through the southwestern coast islands. Further research is needed to determine its population size, distribution, and threats, as well as identify appropriate locations for conservation collection of germplasm.

  • It is very important to provide a parameterized quality of service (QoS) using traffic specification (TSPEC), such as mean data rate, maximum burst size, and peak data rate, when packets from the application layer need to be transmitted with guaranteed services in a high-rate wireless personal area network (HR-WPAN). As medium resources are limited, the optimal medium time required for each device needs to be estimated to share the resources efficiently among devices. This paper proposes a variable-service interval-based resource allocation algorithm to efficiently make a reservation of medium resources based on a parameterized QoS. In other words, the proposed algorithm calculates the number of medium access slots (MASs) based on TSPEC, local resources, and local conditions and determines suitable locations for the MASs within a superframe to accommodate more devices. The simulation results show that the proposed algorithm can accommodate more devices and has greater than 10% resource allocation efficiency in an HR-WPAN compared to existing schemes.

  • This research examines the effect of the relatedness and the gap between Resources and mechanisms on effectiveness of inter-organizational knowledge transfer. According to the literature, there has been a competing theory between two claims; one is that inter-organizational knowledge transfer will be more effective due to the reduction of the transaction cost as the relatedness increases. And the other is that the mutual complementarity of different organizational characteristics will increase synergy. In total, the relatedness and the gap of the Resource and mechanism makes the inverted U-shaped relationship with the inter-organizational knowledge transfer. As the result of empirical analysis about 109 Korean-based Joint Ventures entered country, it shows that the relatedness of parent company's production Resources, learning mechanisms, and coordination mechanisms made the inverted U-shaped relations with the inter-organizational knowledge transfer and the gap of production Resources and adjustment mechanism formed the same relationship. However, the U-shaped relationship has been established in the relatedness of market Resources, but the gap of market Resources and the learning mechanism was not statistically significant. Through this study, I can draw a best conclusion that the inter-organizational knowledge transfer will be more effective when the relatedness and the gap of management resources and mechanisms is in optimal level. However, when it comes to market Resources, it can be inferred that the result could be the opposite because the partner country's market environment would be different.

  • The worldwide shortage of water resources is a major environmental issue. Using pure water for drinking and domestic purposes is a bigger issue than other environmental issues. Industrialization and Urbanization have even polluted rainwater. In China, when it rains, rainwater is stored on the roof or other sources of storage for daily use resulting in pollution. Several studies have been conducted to treat rainwater. The objective of this study is to evaluate the efficiency of constructed wetlands by using ACF as a medium. So, this study aims to treat rainwater in Wuhan city through a Composite Vertical Flow Constructed Wetlands. First, rainwater was stored in the tank while it flows out of the roof, further it is processed in constructed wetlands. The constructed wetlands is consisted with plants Calamus and Chives, adding ACF (prepared from luffa) has achieved great results in this study. Results show that the pollutants have been removed to a considerable level, there were significant differences in removal rates under different HRT at 6h, 9h and 12h respectively. Therefore, Composite Vertical Flow Constructed Wetlands is recommended for total nitrogen and Ammonia nitrogen and total phosphorus.

  • This survey is focused on analyzing amenity resources for the purpose of offering basic sources for balanced development and the activation of sightseeing in Anmyen-island which has superior landscape resources and the result follows as this. 1. As a result of selecting "Amenities characterized in isles" and comparing their applications in order to choose amenity resource surveying method which is suitable for the isle districts where beaches, tidelands, fishing villages and so on are formed, it was considered that the surveying method of the rural amenity resource in the Korean Society of Rural Planning could be properly used. 2. In spite of a variety of amenity resources besides ten beaches, Anmyeon-island has been developed only focused on beaches. Therefore, it is highly recommended to develop new sightseeing courses which connect beaches with adjacent amenity resources such as theme programs. 3. It proved that compared with Anmyeoneup, Gonammyeon has superior landscape resources and higher special product rates, which is caused by the fact that it doesn't have various kinds of amenities. As diverse fish inhabit the sea and tidelands in Gonammyeon, it is beneficial for activating sightseeing tours to develop fishing village experiencing programs including going fishing. 4. Anmyen-island can be divided into East district and West distict by the national road no,77 and two districts have different distributional features of sightseeing amenity resources. In the west district, amenity resources such as coastal sightseeing routes, large event halls, and resorts have been activated in addition to fourteen beaches which have already been developed while the amenity resources in the east like fishing villages, tidelands, and salt fields have not been activated. Accordingly, for activating balanced sightseeing development in Amyeon-island, it is required to make plans which can incorporate the east amenity resources of sea sightseeing and the west amenity resources of fishing village experiencing programs. As a way, constructing sightseeing routes connecting the west and the east district or making a detour lane connecting beaches in the west, Anmyeon pine trees in the center, and fishing villages in the east.
