The purpose of this paper was to understand the basic concepts of Six Sigma and to apply its statistical tools for process improvement in the foodservice industry. Although Six Sigma was originally used for manufactured goods, this case study utilized this innovative tool to control food costs by reducing the quantity of food leftover. The case study was performed in an environment in which Six Sigma Operating System has been already launched for 3 year. Therefore the scope of this study was defined only to the improvement of the specific problem identified above, and any comments for Six Sigma operating system were not included. A five-step methodology (Define-Measure-Analyze-Improve-Control) was used to reduce the food loss. Data were collected from 11 operating accounts, in a company which operates over 100 accounts, for a month and an average amount of the food leftover generated by each account was 55.1 kg per day. The major causes for the food leftover were found such as too much portion size in the standard recipe, no control for the customer forecasting, no inventory adjustment for ordering, cook all amounts of ordered food materials regardless customer counts, and cook over portion on purpose. All improved methods for those problems and finally control plans were proposed. The cost of total food leftover generated during the data collection period accounted for approximately 2.2% of total sales volume at the beginning of the study. After the implementation of Six Sigma, the company reduced the food leftover costs fromm 2.2% to 0.6% out of sales.

陳洪綬의 遺民意識과 〈何天章行樂圖〉

Chen Hong-shou (陳洪綬, 1598-1652) was a late-Ming literati painter who made a significant contribution in establishing and reviving antiquarianism in figure paintings in the history of Chinese painting. Chen was an artist with diverse talents. He was a painter, a calligrapher of high-caliber, a famous illustrator for popular novels and romance, and a poet. Archaic and antiquarian thematic and pictorial styles formed the distinctive quality of Chen’s works. Existing researches on Chen Hong-shou have not yet investigated several important issues, such as how his paintings were inter-related with his state of psychology or to his varied and complex life experiences as a Ming leftover loyalist. I believe that Chen was fundamentally an anguished drifter unsettling in between neither Ming nor Qing dynasty. Ho T’ien-chang in The Pleasure Outing of Ho T’ien-chang can be regarded as a symbol of the collective identity of leftover Ming intellectuals, who decided to become hermit scholars like Tao Yuan-ming. In this imaginary group portrait, Chen Hong-shou depicted the thwarted and conflict-ridden lives of left-over loyalties of Ming dynasty, including the painter himself. Chen represented the main subject of life and culture of his contemporary leftover intellectuals such as Ho T’ien-chang by portraying him as Tao Yuan-ming, a legendary hermit scholar whom Ming loyalists wished to associate themselves with. In The Pleasure Outing of Ho T’ien-chang appears Ho T’ien-chang, who lived in retirement out of suffering and conflict from the fall of his country. He sits tranquil in a quite surrounding, which represents the life of Ho T’ien-chang as a hermit scholar who received high-esteem from Ming loyalists. Large pine trees, bamboos, and Taihu rocks in the background symbolize the pure image of Ho T’ien-chang. The large pine trees extending their branches wide, the bamboos standing behind the pines and the Taihu rocks lying in the foreground all refer to the way of life of a nobleman who does not give up their spiritual nobleness even in perilous conditions. These objects are no mere sceneries. They were traditionally metaphors of unbent will and integrity of the noble men situated in the time of hardships, and they visually amplify Ho T’ien-chang who led his life with a clean and pure spirit despite the desolate reality. However, The Pleasure Outing of Ho T’ien-chang takes note of the tragic reality where such a literati intellectual with exceptional talent and nobleness like Ho T’ien-chang should end his life as a drifter and a hermit scholar. An almost inconspicuous chrysanthemum on the corner of the rock to the right side of Ho T’ien-chang in the painting implies the unfortunate lives of drifters as a visual metaphor. Among the drifting intellectuals, chrysanthemums have thus been regarded as a symbol of hardship and frustration of Ming leftover loyalists. By depicting the portrait of Ho T’ien-chang, Chen Hong-shou attached strong social significance and a high level of pictorial symbolism in The Pleasure Outing of Ho T’ienchang. From the outer appearance, the painting seems to have rendered the “pleasure outing”of Ho T’ien-chang, but it is a symbolical painting of Chen Hong-shou who represents the common “consciousness of Ming leftover”among Ming loyalists and the artist himself.

This study was carried out to provide the improvable way of foodservice management to dietitian in the elementary schools. For this purpose the seving pattern of food, menu planning, nutrition education, leftover management and difficulties in foodservice were inverstigated. The survey was conducted through questionnaires, which were collected from 249 dietitions randomly selected in Taejon and Chung Nam. Data were analyzed by SAS program. The main results of this study are as follows. The children in Taejon took foods in the class room (65.7%) and those in Chung Nam in the dinning hall (89.9% )(p<0.01). In menu planning the balance of nutrition(42.6%) was mainly considered and then food preference(19.7%), variety of menus(16.1%), food cost(16.1%), composition of food color, taste and texture(3.2%), skills of food making(1.6%) and the number of students(0.8%). They referred cooking magazines(47.7%), the previous menu(42.2%), children's opinion(7.2%) for planning menu. The insufficiency of implements and devices for food(24.1%) and lack of season's food(20.4%) were indicated as difficulties in their job. 34.5% of dietitians used a standard menu, 79.5% investigated food preference of children, 74,3% evaluated taste of foods before serving, and 80.7% regularly checked leftover. The major reason for leftover was careless of the teacher in charge in Taejon and bad taste of foods nutrition in Chung Nam(p<0.001). 98.5% of them answered that they had the responsibility for nutrition education in elementary school. They had a hard time in relationship with the staffs in school (40.6%) and employees for food (39.8%), and lack of market information(38.2%). To efficiency of dietitian's work can be enhanced by reflecting the results of children's food preference and leftover, by using standard cooking method and proper cooking untensil, and by performing nutrition education for children by themselves.

The purpose of this study was to investigate dietary intake and to evaluate patient satisfaction toward the quality of hospital foodservice. Questionnaires were distributed to 203 hospitalized patients in 3 hospitals having 300 beds. The intake rates for served amounts of rice, side dishes, and soup were 72.5%, 68.2%, and 62.6%, respectively. The main reasons for left-overs were ‘no appetite’ (25.8%) and ‘not salty enough’ (19.9%). The rate of patients eating outside food was about 33.5%. The average score for quality satisfaction of meal characteristics was 3.34 ± 0.61, and the average score for quality satisfaction of sanitation and service characteristics was 3.58 ± 0.61. ‘Seasoning’ showed the lowest score and ‘temperature’ showed the highest score for quality satisfaction of meal characteristics. In the quality satisfaction of sanitation and services, ‘explanation of meals’ showed the lowest score and ‘exactness of meal times’ showed the highest score. The patients hospitalized for 10 days showed significantly lower average scores than those hospitalized over 60 days for quality satisfaction of meal characteristics. The patients with ‘little appetite’ and ‘regular appetite’ showed significantly lower average scores than those with ‘much appetite’ for the quality satisfaction of meal, sanitation, and service characteristics. The patients who ‘rarely had leftovers’ showed significantly higher average scores than those who ‘always had leftovers’ and ‘often had leftovers’ for quality satisfaction of meal characteristics. Meal characteristic scores were significantly correlated with age (r = 0.216), length of admission (r = 0.310), appetite (r = 0.251), leftovers (r = 0.233), and intake of soup (r = 0.205). Also, sanitation and service characteristics scores were significantly correlated with age (r = 0.327), education (r = -0.202), length of admission (r = 0.168), and appetite (r = 0.155). Thus, it would seem to be desirable that hospital foodservices improve the taste and seasoning of meals and provide appropriate nutrition education and counseling in mid-sized hospitals.

This paper attempts to re-examine a political change or democratization from the perspective of the ‘subaltern’ who are regarded as ‘the other’ or ‘the unrecognized’ dealing with the case of the April Revolution in 1960 in South Korea. This paper aims to place the ‘subaltern’ on a key object of the political analysis by making a political interpretation on them, who presented in the process of the April Revolution, then to give a new analytic meaning to the characteristics of the politics changes in South Korea in terms of democratization. In this sense, this paper begins by questioning how the study of the subaltern can be applicable into the fields of political change and democracy. This paper, then, provides an new analytic account to the understanding of democracy and democratization. As a tentative result, this paper argues that in the contemporary world a certain while democratic order which is unfixed and temporal is reconstructed through a certain political change, it is required to involve a double operation of inclusion and exclusion of the subaltern as the democratic leftover. In particular, whereas focusing the period of the April Revolution, this paper underlines the importance of the study of ‘participants’ in courses of political change and democratization in South Korea. In addition, it contributes to develop political and social perception on the subaltern, then to put issues related to them into social and political agendas.

This study examined the dietary habits and nutrition quotient (NQ) scores according to leftover food during school meal services among middle school students in the Gyeonggi region. A survey on the dietary habits was conducted among 405 male and female middle school students located in Seongnam City, Gyeonggi Province. The amount of leftover food in the school meals was surveyed using the visual method through a questionnaire over two days. The survey was conducted from July 8, 2019, to July 12, 2019. After calculating the average total leftovers of each student over the two days, they were categorized into the following three groups: the top third was the large leftover group. The middle third was the medium leftover group, and the lower third was the small leftover group. The characteristics of the groups that had leftovers were analyzed. Female, normal-weight, and underweight students accounted for a greater proportion of the large leftover group than male, overweight, and obese students. The rates of selective eating and compliance with new food intake were significantly lower in the large leftover group than in the small leftover group. A comparison of the nutrition quotient for the adolescent (NQ-A) scores of each group revealed significantly lower scores of the large leftover group for all factors (balance, moderation, food diversity, practice, and environment) than the small leftover group. Therefore, there are statistically significant differences in the dietary habits, nutritional quality, and eating behaviors of middle school students that are associated with the amount of leftover food during school meals.

일반논문 : 오키나와의 아리랑 -미군정기 오키나와의 잔류 조선인들과 남북한

임경화 ( Kyoung Hwa Lim ) 성균관대학교 대동문화연구원 2015 大東文化硏究 Vol.89 No.-

본고에서는 식민지기부터 오키나와에 거주했다가 패전 이후에도 잔류하게 된 조선인들이 전후 냉전질서 속에서 방치된 후 발견되는 과정을 분석했다. 오키나와에서 미군의 직접통치가 실시되고 20여 년이 지난 후에 이들이 발견된 데에는, 1965년한일협정 이후 이들의 법적 지위를 둘러싼 ‘국가의 논리’가 있었다. 하지만, 한국정부는 이 문제에 대해 초기에는 소극적으로 대처했으나, 오키나와 반환협정 체결 전후로 갑자기 움직이기 시작했다. 반환으로 인한 총련의 오키나와 진출에 위기감을 느꼈기 때문이다. 총련은 오키나와에 오자마자 오키나와 전투에서 희생된 조선인에 대한 진상조사에 착수했다. 이 조사는 군대의 논리에 의한 오키나와 전투의 역사화에 대항해서 전개된 오키나와 주민 주체의 전투 기록운동을 계승한 것이었다. 오키나와 주민들은 ‘주민의 논리’에 입각한 오키나와 전투 역사화 과정에서 조선인들을 발견했다. 총련은 이 성과들을 이어 받으면서도 조선인이 주체가 된 오키나와 전투의 실상을 그리려 했다. 그 결과 조사단은 오키나와 전투 준비를 위해 동원되었던 조선인들 중에 패전 이후 미군의 전쟁준비에 동원된 사람들도 있었다는 것을 밝혔다. 조선인들에 대한 일제와 미군의 전쟁범죄를 고발함으로써 오키나와에는 식민지주의가 지속되고 있었음을 드러내려 한 것이다. 한국정부와 총련의 잔류 조선인에 대한 인식 차는 남북한의 미군정기 오키나와인식이 반영된 것이기도 했다. 한국은 미군의 오키나와 통치를 적극적으로 지지했고 오키나와에 친미반공 독립국의 형성을 지원하기도 했다. 한편 북한은 제3세계해방운동 속에서 민족 재결합이라는 공동 목표 하에 오키나와의 조국복귀운동과 연대했다. 당시 주민의 다수가 복귀를 희망했으므로 남한은 ‘군대의 논리’에, 북한은 ‘주민의 논리’에 서 있었다고 할 수 있다. 하지만, 미군정기의 오키나와에 접근할 수 없었던 총련의 ‘주민의 논리’는 대다수가 민족 해방이 아닌 귀화를 선택했던 잔류 조선인들의 현실에 부합하지 못했다. 그러한 한계에도 불구하고, 전쟁과 냉전의 틈바구니에서 국가와 역사로부터 망각당한 피해자가 발견되었을 때, 피해자의 존재를 품고 역사 속으로 이끄는 안내자의 논리가 될 수 있었다. This paper aims to analyse how the "leftover" Koreans, who survived the battle of Okinawa and then ended up settling down there, were first left to their own devises and neglected, and then re-discovered. One of the reasons why they were re-discovered 20 years after Okinawa came under the direct control of the US military was the "state logic", to be applied to Okinawa Koreans under the terms of 1965 South Korea-Japan Normalization Agreement. However, in the beginning, the South Korean Government did not show an active interest in Okinawa`s Koreans; it started to do so only after Okinawa`s reversion to Japan was agreed by Japan and USA in 1971. The reason for that was the feeling of crisis, as it was understood that the reversion would allow the pro-North Korean Chosen Soren to move freely into Okinawa. The first thing Soren did on Okinawa was the investigation on the Koreans who died during the battle of Okinawa. This investigation continued the civilians-centred history recording movement which took momentum since the late 1960s as a counterforce to the conventional, military-centred descriptions of the battle of Okinawa. As the movement for re-writing the history with the "residents` logic" put squarely in the centre was booming, the remaining Koreans were discovered on Okinawa. The Soren investigation inherited the successes of this movement, while aiming at creating an alternative image of Okinawa battle, with Koreans being its main subject. It was discovered as a result of the investigation that a number of Koreans mobilized in preparation for war by the imperial Japan, were then re-mobilized again by the US military authorities after the Japanese defeat. The aim of the investigation report was thus to accentuate the persistence of colonialism in Okinawa by denouncing the war crimes committed both by imperial Japan and USA. The difference in the view on the "leftover" Koreans between the South Korean Government and Soren reflected the divergence of South and North Korean views on the American military-ruled Okinawa. The South Korean Government was positive on US military rule in Okinawa, supporting also the idea of establishing a pro-American, anti-Communist independent state there. By contrast, North Korea solidarized since the mid-1950s with Okinawan reversion movement as a part of the Third World liberation movement, sharing the common aim of national re-union with the Okinawans. From this viewpoint, we can define South Korea`s logic as more military-based, while North Korea`s logic was closer to the wishes of the majority of general population, which supported the reversion. Soren, however, could not operate in US military-dominated Okinawa. Its "residents` logic", in fact, did not fit into the realities of Okinawa-based "leftover" Koreans, who mostly wished to naturalise rather than to participate in a national liberation struggle. Despite such limitations, Soren still managed to play the role of an aid organization in relation to the "leftover" Koreans. On the discovery of these people victimized and forgotten by the states and official history amidst the vicissitudes of the World War and Cold War, it recognized them and offered them assistance and solidarity.
