        Social investment effects of public education, health care, and welfare service expenditures on economic growth

        Kim SooWan,Ahn Sang‐Hoon 한국사회복지학회 2020 Asian Social Work and Policy Review Vol.14 No.1

        The purpose of this study is to theoretically and empirically examine whether public spending in education, health care, and welfare service operates as a fruitful investment in welfare states, which has been implied in the literature of social investment arguments. Based on comprehensive review of existing literature, this study suggested a tripartite mechanism of social investment effect of such spending, that is “enhancement of human capital,” “support for labor force participation,” and “job creation.” To find the empirical evidence, a pooled time‐series cross‐section analysis was conducted with the data of 15 advanced welfare states from 1980 to 2015 using estimation technique of fixed‐effect model. The results confirmed that public spending in education, health care, and welfare service had a positive medium‐term as well as long‐term effect on economic performance, while cash‐type welfare spending had an obscure or no visible effect on economy. Government consumption that is a proxy and control variable of size of the welfare state showed a positive effect on real GDP in the medium term but a negative effect in the long run. In conclusion, this study suggests that reinforcing social services should be recognized and dealt with as essence of social investment strategy.

        저온환경에서 NR/BR 블렌드 조성비 및 오일함량이 방진고무재료의 기계적 특성에 미치는 영향

        김완수,김완두,우창수,최성신 한국고무학회 2004 엘라스토머 및 콤포지트 Vol.39 No.2

        방진고무의 내한성을 향상시키기 위하여 NR 컴파운드에 유리전이은도가 상대적으로 낮은 BR을 섞거나 오일 함량을 늘리는 방법을 이용하여 새로운 컴파운드를 제작하였다. 저온환경에서 기계적물성 실험을 수행하여 NR/BR 조성비 및 오일 함량에 따른 영향을 조사하였다. BR함량이 증가할수록 경도 및 모듈러스가 증가한 반면 인장강도 및 신율은 감소하였고, 오일 함량이 많을수륵 경도, 모듈러스 및 인장강도는 감소하였으나 신율은 거의 변화가 없었다. NHBR블렌드 고무컴파운드는 NR과 BR의 유리 전이 은도인 -50℃와 -90℃에서 저장한 성계수의 급격한 전이와 손실계수인 tan δ 가 최대값을 보여 두 컴파운드간의 비상용성을 나타내었다. New compounds were made using various NR/BR blend ratio and oil content to improve mechanical properties of rubber isolator at low temperature. Mechanical properties were investigated as a function of NR/BR blend ratio and oil content. Hardness and tensile modulus generally increased, but tensile strength and elongation at break decreased with increasing BR content. Hardness, tensile modulus and tensile strength decreased, but elongation at break were nearly the same with increasing oil content. The glass transition temperature of NR and BR were found to be -50°C and -90°C respectively based on the abrupt drops in storage elastic modulus and peak of loss factor. Two distinct transition temperature were observed in NR/BR blend compounds and each transition point was not affected by blend level indicating incompatible nature of NR/BR blend.

        Background : Malignant melanoma in Korea has been increasing as in other countries, but there is no nationwide survey of malignant melanoma in Korea. Objective : The aim of this study was to document the clinical and histopathological features of cutaneous melanoma in Korea. Methods : The Dermatopathology Research Group conducted a review of nationwide collection of109 primary cutaneous melanomas, diagnosed at 23 institutes over a recent 3-year period. Clinical records and pathology slides of the patients were reviewed retrospectively. Results and Conclusion : 1. The peak age was the 7th decade with the mean age of 58.1 years. Korea has a higher rate of acral melanoma and much lower rate of lentigo maligna melanoma. 2. Major component tumor cell was spindle cell type. 3. Clark level of tumor was Ⅲ or more and Breslow depth was 2 ㎜ or more at the time of the first diagnosis in many cases (62%). 4. Pre-existing melanocytic nevus was present in a few cases (3 cases). 5. All these features suggest that the racial difference between the Korean and the Caucasian is evident. We also suggest that an early detection program is very important to cure this malignant tumor.

        Background : The relative frequency and clinicopathologic characteristics of lymphomas vary according to geography and race. Data on the features of cutaneous lymphoma in Korea we limited. Objective : The aim of this study was to document the relative occurrence, the clinical and histopathological features of cutaneous lymphomas in Korea. Methods : The Korean Dermatopathology Research Group conducted a review of nationwide collection of 80 cutaneous lymphomas, diagnosed at 23 institutes over recent 3-year period. Clinical records and pathology slides of the patients were reviewed retrospectively. Results and Conclusion : 1. Korea has a higher rate of T-cell lymphoma and NK/T cell lymphoma and a much lower rate of cutaneous B cell lymphoma. 2. The relative frequency of the major diagnostic group according to WHO classification was as follows mycosis fungoides/Sezary syndrome, 42.5%; anaplastic large cell lymphoma, 19%; nasal and nasal type NK/T cell lymphoma, 15%; subcutaneous panniculitis-like T cell lymphoma, 11%; peripheral T cell lymphoma, unspecified, 7.5%; follicular lymphoma, 3%; marginal zone Iymphorna, 1%; angioimmunoblastic lymphadenopathy, 1%. 3. Compared with Western countries, the rate of nasal and nasal-type NK/T cell lymphoma and subcutaneous panniculitis-like T cell lymphoma were much higher. Therefore, The EORTC classification is not effective in dealing with Korean cases of cutaneous lymphoma. We consider the principles of the WHO classification are applicable to the Korean cases of cutaneous lymphoma. (Korean J Dermatol 2003;41(1) : 48∼57)

        Background : Data on the clinicopathologic features of hair follicle tumors in Korea are limited. Objective : The Purpose was to investigate the clinical and histopathologic characteristics of hair follicle tumors in Korea. Methods : Two hundred sixty four cases of hair follicle tumors seen from 1999 to 2001 in Korea were analyzed clinically and histopathologically. Results and Conclusion : 1. The most common hair follicle tumor in Korea was pilomatricoma(81.0%), followed by trichoepithelioma(6.4%), dilated pore of Winer(3.8%), and proliferating trichilemmal tumor(2.2%). 2. Hair follicle tumors usually occurred as a solitary skin-colored nodule. The most commonly involved site was the face, and the peak age of presentation was 10 to 19. 3. Pilomatricoma usually occurred as a solitary skin-colored nodule. The most commonly involved site was the arm, and more than 50% of tumors occurred before the age of 20. Histopathologically, the tumor was often surrounded by fibrous capsule and was composed of basophilic and shadow cells. It was usually located in the dermis and extended into the subcutis. Retraction spaces between tumor nests and stroma were frequently observed. 4. Trichoepithelioma usually occurred as multiple skin-colored papules on the face. Histopathologically, the tumor was usually located in the dermis with sometimes connected to the epidermis. It frequently showed peripheral palisading. 5. Dilated pore of Winer usually occurred as a solitary brownish to pigmented papule on the face in middle-aged persons. 6. Proliferating trichilemmal tumor occurred as a solitary or multiple tumors. Histopathologically, the tumor was usually surrounded by incomplete fibrous capsule. Tumor cells frequently showed clear cell formation, nuclear atypia, mitosis, peripheral palisading, trichilemmal keratinization, and individual keratinization.

        김완수 호남대학교 산업기술연구소 2012 녹색산업연구 Vol.18 No.2

        To manufacture commercially available waxy rice flour for providing convenient storage and supply, as a preliminary test, physicochemical characteristics of waxy rice flours and its starches under alkaline conditions using different soaking time and drying treatments were investigated. Results found in this study were as follows: Wet milled rice flour had an improving effect on reducing ash content (down to 30%) and overall color, compared to control(Dry-milled rice flour). WG rice flour showed uniform size of particles with soaking time, compared to DG rice flour, while starches were not much significantly different. Swelling powers and solubilities of WG flour and its starch at 80℃ were higher and lower than those of DG one, respectively, for 1 and 3 days' soaking time. Key words: Waxy Rice Flour, Waxy Rice Starch, Soaking Time, Drying Condition 저장과 유통의 편이성을 제공하는 시판용 찹쌀가루를 제조하기 위한 실험으로 수침처리한 찹쌀가루를 풍건과 분쇄의 순서를 달리하여 제조한 찹쌀가루와 알칼리 침지법으로 쌀가루에서 분리한 전분의 이화학적 특성을 살펴보았다. 그 결과는 다음과 같다. 수침시간에 따라 찹쌀가루의 회분 함량이 대조군(건식제분한 찹쌀가루)에 비해 약 30%까지 감소하여 쌀가루의 전체적인 색도가 향상되었다. WG 찹쌀가루 입자는 DG 찹쌀가루에 비해 수침시간에 따라 균일해졌지만 전분은 건조방법에 따라 큰 차이를 보이지 않았다. 80℃에서 팽윤력과 용해도는 WG 찹쌀가루와 전분이 각각 DG 찹쌀가루와 전분에 비해 각각 높은 수치와 낮은 수치를 보였다. 주요어: 찹쌀가루, 찹쌀 전분, 수침시간, 건조 조건

      • 유기산 첨가가 RS 특성에 미치는 영향

        김완수 호남대학교 산업기술연구소 2014 녹색산업연구 Vol.20 No.1

        To increase the yield of RS3 which gives physiologically active properties, three different concentrations (0.25, 0.5 and 1.0% based on starch amount) of three organic acids (citric, succinic and malic acids) were added to commercial corn starch-water suspension. As a control, RS3 untreated with acid was used. Higher increase in RS3 yield was obtained when the concentration of acid was 0.25% by using pancreatin-gravimetric method, regardless of the type of acid. Compared to control RS3, ratios of yield increase in acid treated RS3s were about 26.7-47.5%. According to SEM, it was observed that exfoliation was accelerated in the surface of all the RS3 particles due to a repeated heating-cooling cycle. The B type of X-ray diffraction pattern was observed from all RS3 samples., indicating retrograded starch. 식이섬유와 유사한 생리활성을 제공하는 RS의 수율을 높이고자, 세 가지 유기산(citric, succinic, malic acid)을 농도를 달리하여 (0.25%, 0.5%, 1.0%, 전분 기준, w/w) 옥수수 전분 현탁액(전분: 물 = 1: 3.5)에 첨가하여 저항전분(RS3)을 제조한 후 그 입자 특성을 살펴보았다. RS 수율은 본 유기산의 종류에 관계없이 산 농도가 0.25%일 때 가장 많이 증가하여 산첨가를 하지 않은 control에 비해 RS3의 수율이 약 26.7~47.5 % 증가되었다. SEM 관찰로, 모든 RS3의 입자 표면은 제조 시 반복된 가열-냉각 과정으로 박리가 가속화되었음을 보여주었다. X선 회절도에 의한 citric acid 처리 RS3의 결정형은 첨가된 산농도에 관계없이 모두 B형의 결정형(노화전분)을 나타내었고 2θ=17̊의 노화피크는 증가하였다.

      • 수침시간과 건조 조건이 다른 멥쌀가루와 전분의 특성

        김완수 호남대학교 산업기술연구소 2013 녹색산업연구 Vol.19 No.2

        쌀 가공용 즉석 쌀가루를 제조하기 위해 멥쌀(일미벼)을 수침처리(1, 24, 72시간)한 후 풍건과 분쇄의 순서를 달리하여 제조한 멥쌀가루와 알칼리 침지법으로 분리한 멥쌀전분의 특성을 살펴보았다. 대조군(건식제분)에 비해 수침시간이 길어질수록 단백질은 DG가, 회분은 WG가 감소하였고 전체적인 밝기(⊿E)가 상당히 향상되었다. 80℃에서 팽윤도(SP)는 건조순서에 관계없이 멥쌀가루는 수침 1시간, WG 멥쌀전분은 수침 24시간, DG 멥쌀전분은 수침 1시간일 때 가장 높았다. 80℃에서 용해도는 대조군에 비해 WG쌀가루는 감소하고 DG쌀가루는 증가하였지만 전분은 모두 증가하였다. To prepare ready-to-use rice flour for the processed foods, characteristics of nonwaxy rice flours which were soaked under different time (1, 24, 72 hours), then air-dried and milled(DG) or milled and air-dried(WG), and of rice starches which were isolated by alkaline conditions were investigated. Compared to a control (raw milled rice without soaking), protein of DG was decreased, crude ash of WG was considerably decreased and the overall brightness(⊿E) of all the soaked rice flours was improved with soaking. Swelling power(SP) at 80℃ of all rice flour was the highest at 1 hour’ soaking, and those of nonwaxy rice starch were the highest at 1 day’ soaking for WG, and at 1 hour’ soaking for DG, respectively. Compared to a control, solubility at 80℃ of WG rice flour was decreased, of DG rice flour was increased, and those of all the rice starches were increased.

      • 밀의 식문화적 고찰과 국산 밀품종의 용도

        김완수 호남대학교 산업기술연구소 2012 녹색산업연구 Vol.18 No.2

        인류 역사에서 가장 오래된 작물의 하나인 밀은 몽고를 거쳐 한반도로 전파된 것으로 추정된다. 6․25 전쟁 후 밀은 미국의 무상원조로 점차 소비가 확대됨에 따라 현재는 국민 1인당 밀소비량이 쌀 소비량의 약 45%를 차지하고 있다. 이로써 자급률이 3%내외인 밀은 대부분을 수입하고 있는 실정이다. 따라서 슬로우 푸드인 국산밀의 사용은 안전한 먹거리 제공, 국민 건강 유지, 환경보존효과, 농가소득증대, 외화절약으로 국가 경제에 이득을 줄 수 있다. 주요어: 밀, 식문화, 국산밀, 품종 It is assumed that one of the oldest crop in human history, wheat has been introduced into the Korean Peninsula via Mongolia. Since the Korea War, by a gratuitous aid from U.S., wheat has gradually been consumed and currently per capita consumption of wheat is almost 45% as much as that of rice. For this, it is a fact that most wheat, whose self-sufficiency rate is barely 3%, is imported from abroad. Therefore, utilization of Korean domestic wheat as a slow food, could supply safe food material, support national health, affect environmental preservation, increase farmers' income and save foreign currency, giving a beneficial effect on the national economy.

      • 전통 발효식품인 젓갈류의 특성

        김완수 호남대학교산업기술연구소 2011 산업기술연구논문집 Vol.17 No.-

        Jeotgals, time-lapse foods, which fresh seafoods are salted, fermented and aged at ambient conditions for a limited time, and with the help of microorganisms or enzymes, some ingredients are decomposed and/or new components are formed, giving increase in nutritional, organoleptical and preserving characteristics. Jeotgals are largely divided into Jeotgal and Sikhae. The former(Jeotgal) is classified into liquid type Jeot for Kimchi making, solid(flesh) type Jeot for side dish and fish sauce for condiment of assorted foods. Sikhae is developed as a substitute for Kimchi in the area of salt shortage, that is, Kimchi style Jeotgal. In this paper, the origin, classification and compositions of Jeotgals, and commercially available those products were reviewed 젓갈류는 어패류를 자연 조건에서 염장 후 발효ㆍ숙성시키면 미생물 또는 효소의 도움으로 식품 성분이 분해되거나 새로운 성분이 만들어져 영양가, 기호성, 저장성이 증가된 시간의 음식이다. 젓갈류는 젓갈과 식해로 분류하는데, 젓갈은 김치에 사용하는 액젓, 반찬(찬품)으로 사용하는 육젓, 조미식품으로 사용하는 어간장 등 여러 용도에 사용되고 식해는 일반적으로 소금이 귀한 지역(함경도, 강원도)에서 발달하여 김치 대용식으로 애용되는 김치형 젓갈이다. 본 논문은 젓갈류의 기원, 분류, 성분 및 시판 젓갈에 대해 고찰하고자 한다.
