청년실업, 명예퇴직, 노인취업문제 등 나이고하를 막론하고 모든 연령층에서 노동력에 대한 수요는 증가하고 있으나 공급은 과거보다 훨씬 줄어들었다. 특히 건강한 에이즈감염인들의 경우 건강에 이상이 없기 때문에 노동에 대한 욕구는 크지만 그들이 처한 상황 특성상 노동의 기회는 제대로 주어지지 않고 있다.

The objective of this study was to carry out treatment of various plant hormones in order to determine morphological and genetic variation degree of tissue-cultured strawberry. The cultivar used in this experiment was 'Goha' and 'Seolhyang', the plant hormones used for experiment were benzyladenine (BA), N-(2-Chloro-4 pyridyl)-N'-phenylurea (CPPU) and thidiazuron (TDZ), and the concentrations were 0.5, 1.0, 2.0, $4.0mg{\cdot}L^{-1}$ with each hormone. The BA treatment of the proliferation efficiency of tissue-cultured strawberry 'Goha' and 'Seolhyang' was the highest. When processing BA, CPPU and TDZ, morphological variation and genetic variation happened in strawberry 'Goha' and 'Seolhyang', especially, the variations appeared highly in CPPU treatment. The genetic variation in 'Goha' appeared at the concentration more than BA $0.5mg{\cdot}L^{-1}$ as 1.1%, appeared at the concentration of CPPU $0.5mg{\cdot}L^{-1}$ as 15.3%, and at the concentration of TDZ $2.0mg{\cdot}L^{-1}$ as 1.2%. The genetic variation in 'Seolhyang' appeared at the concentration of BA $4.0mg{\cdot}L^{-1}$ as 2.3%, and at the concentration of CPPU $0.5mg{\cdot}L^{-1}$ as 14.3%. Therefore, CPPU should not be treated during strawberry tissue culture, and BA and TDZ should be treated at low concentration.

본 연구는 문헌사료와 고분벽화를 토대로 고구려 관복 제도의 변천과정과 특징을 고찰한 것이다. 문헌에 나타난 고구려의 관복 제도를 살펴보면 의복은 유고제를 유지했으며 관등 고하에 따른 유고의 색채나 소재상의 규제는 보이지 않는다. 신분표시의 기능은 주로 관모가 담당했던 것으로 보이는데, 문헌에 나타난 3세기-7세기까지의 고구려 관모 제도를 고분벽화를 참조하며 고찰한 결과는 다음과 같다. (중략)

'Miha' is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2019. The 'Miha' cultivar originates from a 2014 cross between 'Monterey' and 'Saebong No. 3', both of which exhibited excellent ever-bearing characteristics, including continuous flowering and large fruits under long-day and high temperature conditions. This new cultivar was initially named 'Saebong No. 12' after examining its characteristics and productivity during summer cultivation between 2015 and 2019. After regional adaptability tests, 'Miha' was selected from 'Saebong No. 12' as an elite cultivar. The general characteristics of 'Miha' include intermediate, elliptic leaves, and strong growth. The fruits are conical and of a dark-red color. The number of leaves of 'Miha' was 21.9, which was 6.2 fewer than that of the control cultivar, 'Goha' with 28.1. The number of flower clusters of 'Miha' was similar to that of 'Goha'. The average fruit weight of 'Miha' was 13.4 g, which was 4.3 g heavier than that of 'Goha'. The fruit hardness of 'Miha' was 36.2 g·mm^-2, which was 10.1 g·mm^-2 harder than that of 'Goha'. The marketable yield of 'Miha' was 37,393 kg·ha^-1, 156% more than that of 'Goha' with 23,970 kg·ha^-1. Therefore, the new cultivar of ever-bearing strawberry 'Miha' is expected to be very popular in the export or bakery market because it is hard.

This study was conducted to investigate the effects of crown numbers on growth and yield of ever-bearing strawberry (Fragaria ${\times}$ ananassa Duch.) 'Goha' cultivar. Strawberry seedlings were planted with $55{\times}30cm$ distance on April 29, and the randomized block experimental was designed by putting the crown numbers by 1, 3, 5 and crown-unremoved as the control. At the early growth stage, as the numbers of crown decreased, the size of leaf became larger and inflorescence diameter became thicker. Plant height became higher as the number of crown increased at the final harvesting time. Fresh weight of crown-unremoved plants was 118 g, showing 77.2 g higher than that of plants with one crown. Numbers of the developed inflorescence of plants with five crowns and crown-unremoved was 20.1, whereas 6.8 of plants with one crown, resulted in 13.3 more crowns. However, crown number did not significantly affect the fruit quality. As the crown number increased, the average fruit weight was lighter and the marketable fruit rate was shown to decrease significantly. The marketable yield of crown-unremoved plants was $17,372kg{\cdot}ha^{-1}$, showing 68% higher than plants with one crown. Therefore, crown management without thinning crowns was recommended and inflorescence thickness less than 3 mm should be removed for successful production of ever-bearing strawberry 'Goha' cultivar during summer season.

This study was carried out to determine suitable in vitro culture conditions of new ever-bearing strawberry ($Fragaria$ $ananassa$ Duch.), 'Goha'. Four-week old plantlets which were derived from the meristem culture were used in this study. Three different culture media including MS, Gamborg B5 and White medium were used for the plant culture and the medium concentrations were at the 5 levels of $1/3{\times}$, $1/2{\times}$, $1{\times}$, $2{\times}$ and $3{\times}$. Sucrose content ranged at four levels of 1, 3, 5 and 8% (w/v). Crown diameter on the MS medium was thicker (2.1 mm) than in other media. Fresh weight on the MS medium was 482 mg, which was heavier than 88 mg or 260 mg of Gamborg B5 or White medium, respectively. Particularly, 1/2MS medium was found to have higher growth rate than these in other treatments (fresh weight, dry weight and D/F rate). Shoot length in the treatment of 1% sucrose concentration was 3.6 cm which was the longest. Shoot length was in inverse proportion to the increasing concentration of sucrose. Fresh weight was increased up to 3% sucrose concentration, but decreased above 5% sucrose concentration. From the results, we found that the best condition for in vitro culture of new ever-bearing strawberry 'Goha' was 1/2MS medium supplemented with 1% sucrose concentration.
