In this paper, we investigate on the determinants of new venture performance empirically and suggest a new venture performance model in the Korean Information and Telecommunications (IT) industry. A total of seven hypotheses is established and tested using a combination of factor analysis, cluster analysis, analysis of variance, and correlation analysis. Ninety-two sample ventures in the Korean IT industry were investigated and analyzed to test hypotheses. We found that new ventures performance depends on their environment, strategy, internal resources factors, and, most importantly, two-way and three-way interactions of these factors. These findings could be interpreted as supporting the general strategy theory that when environment and internal resources and fitted, performance might be maximized and, further, strategy is the means that make internal resources and environment fit. The venture performance model presented in this paper can explain how new ventures achieve their successes. The strategic implications to the venture firms are also discussed.

There are 60 species of blood-feeding land leeches, 50 species belonging to the family Haemadipsidae and 10 species belonging to the family Xerobdellidae. Despite recent papers on the land leeches, their taxonomic identification is not fully understood, especially at a species level. In Korea, there have been no historical records of the terrestrial leeches, but recently an unrecorded blood-feeding land leech was discovered at Gageo-do (Island), Korea. Molecular analysis was used to identify the species of 29 leeches collected from Mt. Dock-Sil in Gageo-do. Conventional PCR was conducted using nuclear 18S rRNA and mitochondrial cytochrome c oxidase subunit 1 (CO1) genetic marker. The 18S rRNA sequences revealed that the leeches share 99.9% identity with Haemadipsa rjukjuana (inhabiting Taiwan), and the CO1 sequences revealed that the leeches are very close to H. rjukjuana (inhabiting Taiwan). The CO1 sequences were separated into 2 categories, 1 with 94.6% and the other with 94.3% similarity to the H. rjukjuana L00115A (inhabiting Taiwan). This new finding of the land leech is the first record in Korea. In addition, the north range of the distribution of the blood-feeding leech (Hirudiniformes: Haemadipisidae) should be reconsidered including Korea.

This study aims to analyze the influence of apparatus resources, organizational commitment, internal control on the accountability of village fund allocations with the level of education as a moderating. Accountability analysis of village fund allocation is carried out at every stage of planning, implementation stage, administration stage, reporting stage, and accountability stage. The study was conducted in 18 villages in Undaan District, Kudus Regency - Indonesia, with a total sample of 115 village officials. Structural Equation Model analysis techniques with Warp Partial Least Square were used to test the research hypotheses. The results showed that apparatus resources, organizational commitment, and internal control had a positive effect on the accountability of village fund allocations. The level of education strengthens the influence of apparatus resources on the accountability of village fund allocations. The findings of the study further prove that commitment has positive implications for achieving accountability. It means that the higher the commitment made by the government apparatus, the better and higher the effect on accountability in managing public funds. With an ethical commitment of the government apparatus in managing the budget, the use of funds can be in accordance with the planning and designation so that goals can be achieved.

Renewable energy has been interested because of fluctuation of oil price, depletion of fossil fuel resources and environmental impact. Amongst renewable energy resources, hydropower is most reliable and cost effective way. In this study, to develop a new type of micro hydro turbine which can be operated in the range of very low specific speed, a cross-flow hydro turbine with simple structure is proposed. The turbine is designed to be used at the very low specific speed range of hydropower resources, such as very high-head and considerably small-flow rate water resources. CFD analysis on the performance and internal flow characteristics of the turbine is conducted to obtain a practical data for the new design method of the turbine. Results show that optimized arrangement of guide vane angle and inner guide angle can give contribution to the turbine performance improvement.

Three aquatic fungi were isolated from samples of freshwater-deposited plant litter and foam collected in Samcheok, Gangwon-do, and Yeongju, Gyeongsangbuk-do, Korea. Based on their morphological characteristics and a phylogenetic analysis of the internal transcribed spacer (ITS) rDNA region, the three isolates NNIBRFG329, NNIBRFG339, and NNIBRFG19 were confirmed as aquatic fungi: Articulospora tetracladia, Margaritispora aquatica, and Aquanectria penicillioides. These species were known as aquatic fungi but neither species has been previously reported in Korea.

Three endophytic fungal strains were isolated from aquatic plants collected in Jeju. The fungi were identified by sequencing and phylogenetically analyzing their internal transcribed spacer (ITS) regions. Consequently, the three strains NNIBRFG2982, NNIBRFG2984 and NNIBRFG 3040 were confirmed as the fungal species Acremonium tubakii, Colletotrichum cliviae and Cylindrocarpon pauciseptatum, respectively, all of which are new to Korea.

This study aims to examine the effect of a change of leadership on internal environment and organization effectiveness and suggest measures on effective organizational management by analyzing a change of leadership before and after 2nd generation management. There was analysis of a difference of leadership type, organizational structure, organizational culture, management resources, job satisfaction, and organizational commitment between the period of the founders and the period of 2nd generation successors by collecting data from employees of 6 hospitals in Seoul. Also there was analysis of the effect of a change of leadership on internal environment and organizational effectiveness. According to the analysis, it was demonstrated that the factor affecting job satisfaction during the period of the founder was complexity of organizational structure, and there were no factors affecting organizational commitment. In contrast, during the period of the 2nd generation successors, it was revealed that transformational leadership, centralism of organizational structure, and human resources of management resources affect job satisfaction, and transformational leadership, complexity of organizational structure, hierarchical culture of organizational culture, and human resources of management resources affect organizational commitment. Further, after the succession from the founders to 2nd generation successors, as transformational leadership increased, job satisfaction rose, and as developmental culture was reinforced and human resources increased, organizational commitment was heightened. Furthermore, as transformational leadership increased and developmental culture was reinforced, organizational commitment was heightened. Namely, as transformational leadership was reinforced resulting from the succession to 2nd generation, employees' job satisfaction and organizational commitment increased, with circumstances aiming for the actual change.

The genus Hypomyces contains fungi that grow on mushrooms, including agarics, boletes, and Aphyllophorales. While 53 Hypomyces species have been reported worldwide, only one was in Korea. In this study, two new Korean species were identified as H. luteovirens and H. tubariicola based on morphology and internal transcribed spacer sequencing.
