해외 선진국을 중심으로 전 세계적으로 경기침체와 저성장, 저고용이 일어나고 있으며, 고용구조의 변화, 여성 운동, 도시 인구 이동, 환경오염, 장애인 일자리, 저출산 고령화시대, 청소년 문제, 평화문제 등 많은 사회문제들이 생겨나고 있다. 이들 국가는 이러한 다양한 사회문제들을 해결하기 위해 사회 서비스를 제공하고, 사회적 가치를 추구하기 위해 사회적기업(social enterprises), 사회적기업가 등을 육성하고 있다. 이는 우리나라도 마찬가지이며, 국내에 '사회적기업육성법'이 도입된 지 11년이 지났다. 그러나 2018년 10월을 기준으로 사회적기업은 2,030개에 불과한데, 이는 우리나라에서 사회적기업을 창업하고 성공하는 것이 얼마나 어려운지를 의미하는 것이다. 따라서 사회적기업의 창업 결정과 성공요인을 연구하는 것은 향후 사회적기업을 육성하는데 있어 큰 의미가 있다. 사회적기업의 창업의지에 영향을 주는 요인에 관한 연구는 학문적으로 중요한 의미를 갖는데, 선행연구는 사회적기업의 성과분석과 육성방향, 사회적기업가 정신에 초점을 두어왔다. 그러나 사회적기업 창업 활성화에 관한 연구는 이제 시작 단계이며, 특히 사회적기업 창업에 영향을 미치는 요인들의 연구는 미비한 상황이다. 본 연구의 목적은 기존 연구의 공백을 채우고자 사회적기업 창업과 사회적기업에 관한 기존 선행 연구들을 바탕으로 경상남도 대학생의 사회적기업 창업 의지에 영향을 미치는 요인을 실증분석하는데 있다. 이러한 요인들을 파악함으로써 앞으로 경상남도 사회적기업 창업의 활성화를 위해 정부와 대학의 전략적 역할에 관해 논의해 보고자 한다.

The water quality and algal communities in the Daechung Reservoir, Korea, were monitored from summer to autumn in 1999 and 2001. Although the average weekly precipitations during June and July were very similar in 1999 and 2001, they were much different during August and September, the so-called blooming season. The rainfall in 1999 increased about 70% after late August, whereas it decreased to the one-fifth level in 2001. The higher concentrations of chlorophyll- a, phycocyanin, and cyanobacteria were observed in 2001, which resulted in the dense algal bloom. In addition, in 2001, the cyanobacterial percentage remained above 80% during the investigation period, and the cyanobacteria were exclusively composed of Microcystis spp. Conversely, there was no report on the algal bloom in 1999. However, the peak bloom seasons were the same for both years, from late August to early September, irrespective of the amount of precipitation. These results suggest that the magnitude and duration of rainfall before bloom season are important factors determining the extent of cyanobacterial bloom in this system.

In this study, we analyzed and compared the constituents of Southern ecotype garlic cultivars, Namdo and Daeseo garlic, cultivated in volcanic and non-volcanic ash soil in Jeju Island and compared the soil properties in these regions. The volcanic ash soil in which Namdo garlic grew had higher electrical conductivity and more available sulfur, whereas the volcanic ash soil in which Daeseo garlic was cultivated had a higher amount of organic matter and total nitrogen. Also, non-volcanic ash soil in which Namdo garlic was cultivated had higher levels of available phosphorous. Namdo garlic cultivated in volcanic ash soil had high levels of total soluble solids and a high allicin content and Daeseo garlic exhibited a higher reducing sugar content. Furthermore, amongst the macroelements found in garlic grown on Jeju Island, potassium was highest, followed by sulfur, magnesium, calcium, and sodium. Iron was the most abundant micronutrient, followed by zinc, manganese, and copper. These results will be of interest to farmers aiming to cultivate high-quality garlic.

This study was conducted to provide a rational forest management method for a natural oak (Quercus variavilis) forest stand in the central part of South Korea based on characteristics of growth and water relation parameters. Average volume per hectare was 175.1 ㎥ in the study site of oak stands. Basal area and volume of each direction appeared to increase as the slope direction moves from north to south, but annual mean increment and periodic annual increment of DBH for 10 years showed the lowest value at the southern aspect. Maximum water potentials measured between 12 and 14 o'clock were analyzed by direction and elevation in the oak stands. Water potential of oak decreased as the slope changed from the north to the south aspect and water potential increased at lower elevations. Soil water content for the oak stands tended to decrease as the aspect shifted from north to south. Water potential and soil moisture content were highly correlated. It appears that oaks have a higher moisture requirement at the southern aspect, because of stand density related to intraspecific competition.

Seasonal succession of algae and water quality parameters were studied in artificial reservoirs in Daegu city from 2000 to 2001. The algal succession was evaluated with respect to dom-inant class and their frequencies. Succession order of algae in two reservoirs was : Bacillariophyceae longrightarrow Chlo-rophyceae longrightarrow Cyanobacteria longrightarrow Bacillariophyceae longrightarrow Bacillariophyceae longrightarrow Cyanobacteria longrightarrow Cyanobacteria longrightarrow Cyanobacteria. This succession order was different from other studies. The local environment condition maybe affects the succession of algae in these reservoirs. As result of correlation analysis between algal biom-ass and water quality parameters, we got low correlation coefficients. Also we got low correlation coefficients between chlorophyll-a and algal biomass. Between chlorophyll-a and water quality parameters, we got high correlation coefficients. An approach having attention to cell biovolume rather than cell number is made to understand the algal community and the ecosystem of reservoir.

The objective of this study was to isolate algae growth inhibiting microorganism to biologically control Microcystis aeruginosa, which is a harmful cyanobacterium. Various bacterial strains were isolated in this study, and four bacterial strains of M1~M4 exhibited remarkable growth inhibiting activity against M. aeruginosa. Based on the 16S rRNA analysis, the isolated M1~M4 strains were identified, and isolated four strains were rod-type and gram-negative. In particular, as well as respective single strain, co-culture of the isolated M1~M4 strains showed obvious algicidal activity against M. aeruginosa. When mixed four strains were inoculated, about 50% of the chlorophyll a was reduced after two days, about 70% after four days, and about 80% after seven days. From these results mentioned above, the four bacterial strains may contribute to the control of harmful M. aeruginosa.

Since some cyanobacterial isolates under selective culturing conditions are lacking of characteristic specialized cells or showing altered morphology, the morpho-taxonomic criteria are not accurate enough to discriminate between species. Instead of morphological parameters, a method based on the single or the combination of repetitive oligonucleotides in a single PCR, repetitive oligonucleotides-primed PCR (ROP-PCR), was applied to generate DNA profiles for members of the cyanobacterial genera Anabaena and Oscillatoria, both of which are responsible for causing poisonous blooms in various freshwater systems. ROP-PCR performed on 10 isolates of the cyanobacteria with ERIC and REP sequences from gram-negative bacteria, STRR1A and LTRR sequences derived from cyanobacterial genome, and eukaryotic repetitive sequences, led to the identification of distinct genotypes, and provided specific and repeatable DNA fingerprints for cyanobacterial isolates. Grouping analysis of cyanobacterial isolates showed a signifiant difference depending on the primer used in PCR.

This study was conducted to provide a national forest management method for natural Pinus densiflora forest stands in central South Korea based on growth characteristics and water relations. Average stand volume per hectare was 259.3㎥ in the pine study site. Basal area, volume, annual mean increment and periodic annual increment of DBH for 10 years at each slope aspect appeared to decrease as the aspect shifts from north to south. Stems per hectare showed the lowest value at the northern aspect. Maximum water potentials measured between 12 and 14 o'clock were analyzed by aspect and elevation. Water potential of pine decreased as the aspect changed from north to south, and water potential increased at lower elevations. Soil water content for the pine stands tended to decrease as the aspect shifted from north to south. Water potential and soil moisture content were highly correlated. Soil water deficits indicate that pines have a higher moisture requirement on the ridge and the southern aspect.
