These studies were conducted to find the effects of laser ablation OTR film types on MA package in perilla leaf, rape, pak choi and chicory sort of leaf vegetable. They were treated at two different temperature conditions and storage for 7 days, except the rape 25℃ treatment, which was stored for 5 days with four types of laser ablation film such as 3,000 cc, 5,000 cc, 7,000 cc and 10,000 cc/m2·day·atm films for perilla leaf and pak choi, 10,000 cc, 20,000 cc, 30,000 cc and 40,000 cc for rape, as 5,000 cc, 7,000 cc, 10,000 cc and 20,000 cc for chicory. In the all treatments, fresh weight loss rate was lower than 0.8% in 12℃, 1.6% in 25℃ except for the 10,000 cc film of perilla leaf. In the carbon dioxide contents, perilla leaf was maintained at the lowest in 12℃ and 25℃ for 10,000 cc, rape was maintained 3-4% in 30,000 cc and 40,000 cc at 12℃, and more than 6% in all film when finish stored at 25℃, pak choi was maintained about 5% except for the 3,000 cc film in 12℃, and chicory was showed average 3% that slightly higher at 12℃ in the 20,000 cc and increase more than 12% at 25℃ in all treat films. Ethylene content tended to be low with higher gas transmission film, but rape treated with the 10,000 cc and pak choi treated with the 3,000 cc film showed low content than average. It was considered that high carbon dioxide and low oxygen content inhibited ethylene occurrence. Rape was highly damaged by yellowing, but perilla leaf cleared. The 5,000 cc film at 12℃, 7,000 cc film at 25℃ for perilla leaf and the 10,000 cc film at 12, 25℃ for rape and 3,000 cc film at 12, 25℃ for pak choi and the 20,000 cc film at 12℃, 5,000 cc film at 25℃ for chicory had the best visual quality through panel test. In the off-flavor, the 7,000 cc film at 12, 25℃ for perilla leaf and 20,000 cc film at 12, 25℃ for rape and 7,000 cc film at 12℃, the 3,000 cc film at 25℃ for pak choi and 5,000 cc film at 12, 25℃ for chicory showed the best results. The conclusion was 5,000 cc and 10,000 cc films were the best film for MA storage at 12℃ and 25℃ in perilla leaf because it showed the best quality of visual quality and off-flavor. In the case of rape, 12℃ treatment was better than 25℃, and the 10,000 cc film showed the best results in carbon dioxide contents and off-flavor. In pak choi, the 3,000 cc film treatment was better than other films at off-flavor, carbon dioxide and visual quality for 12℃ MA storage, and the 10,000 cc film treatment was better than other films at off-flavor and visual quality. The 20,000 cc firm was the most reasonable treatment in both storage temperatures for chicory.

This study purposes to explore the way in which global capital influenced the process of organizing workers in the Korean film industry, and to examine the workers` consciousness that the film workers adopted in the process of building their own union. On the one hand, we specifically focus on the structural causes of organizing the union, such as the weakened government`s protection of the domestic film industry and the decreased number of film products caused by the economic crisis, which mainly affected the livelihood of film industry workers. On the other hand, we carefully analyze the workers` consciousness that the film industry workers have through the in-depth interviews. The Korean Film Workers Union is the outcome produced by the two different desires in the film industry: the producers` desire to have the rationalized production system reinforced by the global capital, and the workers` desire to have a standardized labor process which can assure them of secured paychecks. The workers came to realize that they had a right to demand a fair wage and working conditions through organizing their own union; however, the identities these workers had seemed a little confusing because they were still negotiating their identities between the film artists and film industry workers.

유통 서비스업 여성비정규직 노동의 성격과 차별 양상에 대한 연구

최인이(Inyi Choi) 한국사회학회 2009 韓國社會學 Vol.43 No.1

본 논문은 대표적인 유통서비스업의 하나인 백화점 사업장에서 관찰되는 간접고용 여성 비정규직 노동자의 고용 현황과 이들의 노동생활에 대해 분석하는 것을 목적으로 한다. 백화점의 여성 비정규직 노동자들의 사례는 성별 직무분리의 원칙이 적용되는 내부노동시장과 노동과정상에서 발생하는 여성에 대한 차별 그리고 정규직과 비정규직의 구별에서 발생하는 차별의 양상이 중첩되어 있음을 보여준다. 즉 남성 정규직 대 여성 정규직 그리고 여성 정규직 대 여성 비정규직의 그리고 심지어 여성 직접고용 비정규직 대 간접고용 비정규직이라는 매우 복잡한 고용관계 상의 위계를 보여준다는 점에서 시사하는 바가 크다. 백화점에서 근무하는 간접고용 비정규직 여성 노동자들은 고용위계상 가장 하층에 위치하면서 제도적 차별과 사회적 차별, 그리고 노동조합 활동에서의 차별 등을 동시에 경험하고 있다는 것을 알 수 있다. 제도적 차별은 고용안정성, 임금, 근로조건, 교육 등 내부노동시장 시스템을 통해 나타나는 차별을 의미하며, 사회적 차별은 중요한 업무로 인식되지 않는 주변업무 중에서도 한차례 더 분리되어 외주화된 직무에 배치되어 일함으로서 겪게 되는 일터에서의 차별과 사회적 고립을 의미한다. 노동조합 활동에서의 차별은 비정규직 노동자들이 불안정한 고용상태로 인해 조직화가 불가능한 조건 속에서 원청기업의 노동조합으로부터도 전혀 노동권을 보호받지 못하는 현실에서 잘 나타난다. 이러한 차별의 양상들은 최근 제기되고 있는 노동시장의 양극화 현상과 직접적인 관련이 있다. 2007년 7월 비정규직법 시행이후 증가하고 있는 간접고용의 증가는 비정규직 노동자들의 노동생활의 질을 현저히 떨어뜨려 노동시장의 양극화를 심화시킬 뿐만 아니라 나아가 정규직 노동자들의 고용불안까지 가중시킬 것으로 예상된다. This paper purposes to analyze the employment relations and the work-life of female nonstandard workers who are indirectly employed as the outsourcing workforce by department stores. The case of female nonstandard workers in the department stores shows that the discrimination against these female workers is shaped by both the gender discrimination and the exclusion of nonstandard workers. In the department stores, a complicated hierarchical structure has been produced by the types of employment, such as male standard workers, female standard workers, female nonstandard workers who are directly employed, and outsourced female workers. Outsourced female workers in the department store have experienced both the institutional discrimination and the social discrimination. The institutional discrimination is caused by the inequality in the wage, working conditions, promotion system, and education while the social discrimination is generated by the exclusion of outsourced workers from social relations in the workplaces and from the union organized by standard workers. The discrimination against outsourced female workers can be seen as an example of increasing bipolarization in the Korean labor market. According to this research, it is expected that the increase of the outsourcing workforce after the enactment of the bill on nonstandard workers aggravates the livelihood of nonstandard workers, the bipolarized labor market, and the status of standard workers.

Experiments were performed to understand the effect of hot water treatment on storability of fresh cut paprikas which are normal fruits and disorder fruits, such as blossom end rot and button. The fresh weight loss of fresh cut packed with 25um ceramic film was less than 1%. and there were not quality deterioration due to fresh weight loss. A carbon dioxide content in 25um ceramic film was increased rapidly after 5 days storage at 10℃, and that of `Helsingki` was higher than that of `Special`. The carbon dioxide content of `Helsingki` did not show any significantly difference, but fresh cut treated hot water showed higher carbon dioxide content than control. There were not a tendency among normal and disorder fruits A oxygen content in 25um ceramic film was decreased constantly during storage, and reduced to less than 5% after 10 days storage at 1 0℃. Although there were not significantly different between treatment, the oxygen content of normal fruit fresh cut treated hot water showed the highest. The ethylene content in 25um ceramic film was increased for early storage period, and decreased after 3 days storage at 10℃. The content of ethylene was less than 3 ㎕/ℓ after 3 days storage at 10℃. The hot water treatment did not influence the ethylene content in film. The visual quality of fresh cut was maintained higher in normal fruits than disorder fruits. and that of `Special` cultivar showed higher than `Helsinki` cultivars. But the hot water treatment decreased the visual quality of fresh cut. There was not significantly different in water exhaust contents of freus cut. The soluble solide of `Special` cultivar was reduced by hot water treatment, but that of `Helsingki` did not any difference among treatments and fruit types.

최인이(In-Lee Choi),김일섭(Il Seop Kim),강호민(Ho-Min Kang) (사)한국생물환경조절학회 2008 생물환경조절학회지 Vol.17 No.4

우리나라 수출 작물로 가장 큰 비중을 차지하는 파프리카의 두 품종을 성숙 정도와 저장 조건을 달리하여 저장성을 비교하였다. 국내에서 많이 재배되는 'Special'과 'Fiesta' 두 품종을 수경재배하여 미숙과와 완숙과 상태로 수확한 후 무공 필름과 유공 필름으로 포장하여 4℃와 9℃에 저장하였다. 가장 긴 저장 수명을 보인 저장 조건을 4℃에 포장 내 5%의 이산화탄소와 10%의 산소 농도를 보인 무공처리였다. 무공처리의 경우 저장온도, 품종, 숙기정도에 관계없이 3~9㎕/l의 에틸렌 농도를 보였으나 경도와 생체중 유지에 효과적이었으며 유공처리와 비교해서 부패율에도 차이가 크지 않았다. 50% 착색된 반숙과의 과피색은 9℃와 무공 필름 처리에서 많이 착색되었으나, 완숙과 수준까지 진전되지는 못하였다. 4℃에서 20일간 저장한 후 상온에서 3일간 정치한 완숙 'Special'의 저온 장해 정도를 전해질 용출량과 호흡 속도로 비교한 결과, 무공필름 포장에서 가징 효과적으로 억제되었다. 따라서 파프리카의 장기 유통 및 저장을 위해서는 적절한 무공필름 포장과 저온장해가 발생하지 않는 범위의 저장장이 필요하리라 생각된다. The sweet pepper (paprika) is one of the most important exported vegetable crops in Korea. This study evaluated the storability of sweet pepper fruits between 2 cultivars with different maturities under different storage conditions. The sweet peppers ('Special' and 'Fiesta') were grown in a rockwool hydroponic system, and harvested two different maturities: half-maturity and full-maturity levels. The sweet pepper fruits were stored in MA(non-ventilated) and non-MA(ventilated) conditions at 4 and 9℃ for 20 days. The storability of sweet pepper fruit was the highest in 4℃ MA conditions that remained 5% carbon dioxide and 10% oxygen during the storage. The ethylene concentration in MA condition showed 2~8 ㎕/l regardless of storage temperatures, cultivars and maturities. The fruits packaged with non-ventilated film, showed lower weight loss, and higher firmness, and there was no different about decay ratio compared to the fruits packed ventilated film. The coloration of semi-matured fruit that colored 50% before storage progressed taster in non-ventilated packaging condition at 9℃, but their color did not changed as same as level of full-matured fruit. The electrolyte leakages and respiratory rate that estimated degree of chilling injury was highest in non-MA(ventilated) conditions of 'Special' full matured fruit placed at room temperature for 3 days following storage at 4℃ for 20 days. It may be suggested that sweet pepper fruit packed sealed (nonventilated) film and stored at non-chilling temperature can be maintained better quality for long term storage.

본 연구는 장기 저장 유통을 위해 MA 저장에 적합한 품종 선발을 위해 2011년에 9개, 2012년에 12개의 파프리카 품종을 대상으로 품질과 저장성을 비교하였다. 2011년도 실험에서는 빨간색 품종 중에 과중, 경도 그리고 당도이 높고, 에틸렌 발생률이 낮으며 저장수 명도 23일로 두 번째로 길었던 ‘Mosanto 7044’이 노란색 품종에서는 경도와 당도가 높고, 에틸렌 발생률이 낮았던 ‘Stayer’가 우수하였다. 2012년도 실험에서는 빨간색 품종 중에 과중, 과피두께, 경도가 높고, 부패율과 에틸렌 발생률이 낮으며 저장 수명이 28일로 세 번째로 길었던 ‘Nagano’가, 노란색 품종에서는 과피두께, 당도, 비타민 C 함량이 상대적으로 높았고, 에틸렌 발생률이 낮으며 저장수명이 26일로 가장 길었던 ‘Freestar’가 가장 우수하였다. 과실 품질 특성과 저장수명과의 상관관계를 비교한 결과 에틸렌(r = ?0.5504)과 당도(r = 0.6112)가 고도의 상관 관계를 보였다. This study was carried out to compare the storability in MA storage and quality of paprika fruits among 9 cultivars grown in 2011 and 12 cultivars in 2012. ‘Mosanto7044’ was the most proper cultivar in red-type paprika has grown in 2011 for MA storage, because it showed relatively higher fruit weight, firmness, soluble solid content, and the lowest ethylene production rate, as well as the second longest shelf life. ‘Stayer’ was suitable cultivar in yellow-type paprika cultivated in 2011, because it showed higher firmness, soluble solid content and lower ethylene production rate than other cultivars. ‘Nagano’ was the most proper cultivar in red-type paprika has grown in 2012 for MA storage. Because it showed relatively higher fruit weight, firmness, flesh thickness and the lowest ethylene production rate and decay ratio, although the shelf life of ‘Nagano’ was the third longest (28 days). ‘Freestar’ was the excellent cultivar in yellow-type paprika cultivated in 2012, because it showed higher firmness, vitamin C content and lower respiration rate than other cultivars and the longest shelf life of 26 days. The shelf life had a high correlationship with ethylene production rate (r = ?0.5504), and soluble solid (r = 0.6112), as comparing with the shelf life and the fruit characteristics of 21 cultivars paprika has grown in 2011 and 2012.
