Co-operative education and internships are generally treated as an alternative way to increase the employment rate by resolving the mismatch between college education and the industrial needs of the job specification. Based on a questionnaire survey on Korean universities, this study examined the current status of programs and the operating mechanism for co-operative education and internship to provide policy suggestions for promoting the depth and width of co-operative education in Korean universities. The results of the survey shows that the majority of students carry out internships on a short-term basis and the universities usually lack the capabilities for effectively running the programs of co-operative education and internships. In particular, as a part of the academic curriculum, co-operative education should be focused on the balance and effective linkage between the occupations given to students and the majors in university.

The purpose of this research is to provide basic materials in developing an efficient career guidance method of Vocational High Schools on the basis of analyzing awareness differences in students, teachers and between students and teachers as well as awareness differences according to a position of teachers in terms of the actual condition of career guidance and improvements with the target of students and teachers at Vocational High Schools. The survey was carried out by targeting students and teachers at Vocational High Schools in the Seoul Metropolis. The results of this research are as follows. First, it appeared that the awareness of students on the career guidance level of Vocational High Schools is insufficient, and students answered that employment guidance is more insufficient compared to educational guidance. In addition, the awareness of students on the career guidance conditions appeared to be generally insufficient. Second, in case of awareness of teachers on the career guidance conditions of Vocational High Schools, teachers answered that arrangement of teachers in full charge of career guidance, career counselling room, securing and utilization of latest career information and information search systems capable of using the internet for career guidance are sufficient, whereas they answered that time for career guidance, operating budget of a career counselling room and linkage with external institutions are insufficient. Third, they answered that career guidance conditions are generally sufficient in the order of a principal, vice-principal and teachers. The principal is cognizing that career guidance conditions are sufficient all question items, and the vice-principal answered that career guidance conditions are insufficient in only operating budget of a career counselling room and linkage with external institutions. Teachers answered that career guidance conditions are insufficient in only time for career guidance, operating budget of a career counselling room and linkage with external institutions. In addition, compared to teachers, the principal was cognizing that career guidance conditions are sufficient except operating budget of the career counselling room through analysis of awareness difference among principle, vice-principle and teachers. Fourth, students answered that career guidance conditions are insufficient in all question items, but teachers cognized that career guidance conditions are sufficient in all question items excluding time for career guidance. Among them, what showed a difference of the biggest awareness was analyzed as information search systems capable of using the Internet.

One of the biggest problems of Korean economy is polarization of firms for export and domestic demand and that of conglomerates and SME's achievement. One of the culprits lies weakness of intermediate industry such as machine tool. Since intermediate industry is important path where export performance affects domestic demand and whose actor usually is SMEs with high spill over effect in labor market. Especially, intermediate industry Is vulnerable because of industrial policy biased In backward linkage effect. However if a country fails to develop intermediate industry above some critical point, that country would fall in low-tech equilibrium without growth. In case of benign circle where final goods industry growth leads growth of intermediate industry and again it leads that of final goods industry, it can reach high-tech equilibrium. By contrast, in opposite case where in industrialization latecomer fails to link industries likewise above some critical point that country would fall in low-tech equilibrium without growth. Moreover, for several reasons, machine tool firms of Korea have difficulty in catching up technology above critical point. Firstly. Conglomerate demander neglects their product. Secondly, even after success of development overcoming difficulties they fail to get market share for response of dumping of foreign competitors. And the last one is patent litigation of foreign competitors that incapacitate the technology development. For these, Korean machine tool firms fell in 'middle-income country trap' itself, since they stuck in some extent when they technologically catch up. Consequently, for latecomer country in machine tool industry to leapfrog meaningfully policy support is necessary, Weak intermediate industry does not Induce domestic firms and remained fragile. Therefore, localization, policy should reflect condition of technological catch up more than before, in order to be effective and fruitful. There should be turning point over relationship between conglomerates, major demander of machine tool and SME's, for only with active purchasing of conglomerate Korean machine industry can grow.

Silkworms sex determination drew high attention from researchers. Sex chromosomes on the silkworm are of ZW type for females and ZZ type for males. Chromosome W plays an important role in sex determination. Although several molecular linkage maps have been constructed for silkworm, very few markers are discovered on the W chromosome. In order to look for molecular markers and to further locate the Fern gene on chromosome W, we used genomic DNA from both female and male larvae of a silkworm strain named 937 as PCR templates for RAPD amplification with 200 arbitrary 10-mer primers. The amplification results showed three female-specific bands, namely ${OPG-07_496}, {OPC-15_1,660} and {OPE-18_1,279}$. Further verification, however, revealed no band from OPG-07 and OPC-15 in either sex in the strain 798, but OPE-18 provided female-specific band in the strains Suluan7 and C108, and absent in both males and strain 798. This indicates that the bands from ${OPG-07_496} and {OPC-15_1,660}$ are probably female-specific in strain 937, and the band from OPE-18 was probably amplified from a common segment shared by most strains. The genomic DNAs from OPG-07 and OPC-15 were cloned and sequenced. Sequence analysis showed that the DNAs from OPG-07 and OPC-15 have high identities with the retrotransposable elements, and DNA from OPC-15 contains a portion of sequence which probably encodes an eukaryotic translation initiation factor 4E binding protein (eIF4EBP).

Sixteen genomic DNA simple sequence repeat (SSR) markers of Lentinula edodes were developed from 205 SSR motifs present in 46.1-Mb long L. edodes genome sequences. The number of alleles ranged from 3-14 and the major allele frequency was distributed from 0.17-0.96. The values of observed and expected heterozygosity ranged from 0.00-0.76 and 0.07-0.90, respectively. The polymorphic information content value ranged from 0.07-0.89. A dendrogram, based on 16 SSR markers clustered by the paired hierarchical clustering' method, showed that 33 shiitake cultivars could be divided into three major groups and successfully identified. These SSR markers will contribute to the efficient breeding of this species by providing diversity in shiitake varieties. Furthermore, the genomic information covered by the markers can provide a valuable resource for genetic linkage map construction, molecular mapping, and marker-assisted selection in the shiitake mushroom.
