Demand for energy consumption reduction is increasing according to the development expectations of future mobility. Lightweight structural materials are known as a method to reduce greenhouse gas emissions and improve energy efficiency. In particular, fiber reinforced polymer composite (FRP) is attracting attention as a material that can replace existing metal alloys due to its excellent mechanical properties and light weight. In this paper, industrial applications and research trends of carbon fiber reinforced composites (CFRP, carbon FRP) and self-reinforced composites (SRC) were reviewed based on the reinforcement, polymer matrix, and manufacturing process. In order to overcome the expensive process cost and long manufacturing time of the epoxy resin-based autoclave method, which is mainly used in the aircraft field, mass production of CFRP-applied electric vehicles has been reported using a high-pressure resin transfer molding process including fast-curing epoxy. In addition, thermoplastic resin-based CFRP and interface enhancement methods to solve the recycling issue of carbon fiber composites were reviewed in terms of materials and processes. To form a perfect matrix-reinforcement interface, which is known as the major factor inducing the excellent mechanical properties of FRP, studies on SRC impregnated with the same matrix in polymer fibers have been reported. The physical and mechanical properties of SRC based on various thermoplastic polymers were reviewed in terms of polymer orientation and composite structure. In addition, a copolymer matrix strategy for extending the processing window of highly drawn polypropylene fiber-based SRC was discussed. The application of CFRP and SRC as lightweight structural materials can provide potential options for improving the energy efficiency of future mobility.

The primary purpose of this study is to estimate the structure of Byeongpungsadaseok (屛風莎臺石) and Nanganseok (欄干石) in Geonwonneung (建元陵) and Heonneung (獻陵), which were built in the early of 15th century, based on the Annals of King Sejong. In addition, the ultimate purpose of this study is to reveal structural changes and their significance by comparing the differences with the contents of the dismantlement survey. Geonwonneung, Jereung(齊陵), and Heonneung were repaired at the same time in 1442, and the structural changes were the similar. The purpose of the repair in 1442 was to prevent water from flowing into the underground palace with smooth drainage. As a result of estimating the structure of Geonwonneung and Heonneung according to the records of the Annals of King Sejong, it was created in a very similar form to the Hyeonneung and Jeongneung of Goryeo. And it was clearly recognized that the Royal Tomb of Goryeo was followed. However, as the structure was improved in 1442, the unique characteristics of the Royal Tomb of the Joseon Dynasty were formed. First is the appearance of the Bokbuhyeong lime (覆釜形石灰, which is a convex roof on the Byeongpungsadaseok that serves to prevent rainwater from penetrating into the burial mound. It also plays a role in connecting and fixing the Manseok (滿石) and the Inseok (引石), which are the upper structures of the Sadaseok (莎臺石). Second, the Bakseok (薄石) between the nanganseok and the sadaseok has been transformed into the Sangseok (裳石) with a slope. This plays a role in protecting the inner stone chamber by expanding the length of the bakseok, which forms an overall slope, like the eaves of the roof. After both of these features were first attempted in 1442, they were applied to all Royal Tombs of the Joseon Dynasty and became unique features of these Royal Tombs.

Shaman's play is significant in that it provided public theater for a long time in the theatrical and dramatic history. Unlike upper class who could call entertainer or Korean geisha in the traditional society, the majority of ordinary people could see professional performances through gut. Therefore, the shaman of the traditional society pulled the play which developed in the gut and the outside play into the gut and prepared the performance street for the ordinary people. shaman's play, apart from the religious context, has also functioned as a theatrical performance. Through shaman's play, you can see the process of ritual development into play. Shaman's play is a ritual ritual of expel calamity in an agriculture based society. In Korean consciousness, evil spirits are thought to bring disease or disaster to humans, so they should be good for evil spirits. This is a ritual that goes hand in hand with the Confucian Yeoje and the Buddhist Suryukjae. Most traditional plays, including masque performance, tend to weaken and become stifling after the designation of intangible cultural properties. However, shaman's play is transformed every time it is executed and is given a new meaning. Depending on the ability of the shaman to respond to and accommodate social change, adaptability is excellent depending on the situation in the field. Shaman's play has richness, prevent calamity and playful elements such as imitation of god and sexual connection based on the element of shamanism. In addition, it is necessary to pay attention to the meaning and the direction of Shaman's play because it is differentiated into play including social subject beyond mere magic imitation.

This study examines the failure experience and aspirations for future among Korean adolescents and their parents using indigenous psychological analysis. The first part of this paper reviews the achievement literature that has used indigenous psychological analysis. The second part of this paper provides an empirical analysis of 482 students (primary=117, middle school=88, high school=72, and university=205) and 507 parents of the adolescents (fathers= 236, mothers=271). The open-ended questionnaire developed by Park and Kim (1999) was adopted for the study that asked the respondents to list the most painful experience, the person that was the most responsible for the failure, and the most important reason for the failure. The section on aspirations for the future asked the respondents to list the achievement that they would most likely to succeed, the person that they need assistance from, the type of support they need from the person, and the most important factor that would lead to them to success. The results indicate that for students the most painful failure was related to academic failure and for adults, it was related to family life. The person that was most responsible for the failure was reported by both samples be themselves. As for the most important factor that influenced their failure was a lack of self-regulation, such as a lack of effort and persistence. For the aspiration for future, students listed academic and occupational success and for adults listed harmonious family life as the most important. For social support, the adolescents listed their parents and adults listed their spouse as the person that they need assistance from. As for type of support, they listed emotional support to be the most important. As for the most important factor that would contribute to their success, majority of students and adults listed self-regulation. Based on these results and previous indigenous studies indicate, the following four conclusions could be drawn: (1) the emphasis of self-regulation as the most important reason for their past achievement, the future success and the lack of self-regulation for their failure; (2) the importance of receiving emotional support from family members; (3) the importance of educational aspiration and achievement for providing the basis of economic development; and 4) the importance goal of achieving harmonious family life.

Extracellular $K^{+}$ concentration ([ $K^{+}$]$_{0}$ ) can be increased within several mM by the efflux of intracellular $K^{+}$. To investigate the effect of an increase in [ $K^{+}$]$_{0}$ on vascular contractility, we attempted to examine whether extracellular $K^{+}$ might modulate vascular contractility, endothelium-dependent relaxation (EDR) and intracellular $Ca^2$$^{+}$ concentration ([C $a^2$$^{+}$]$_{i}$ ) in endothelial cells (EC). We observed isometric contractions in rabbit carotid, superior mesenteric, basilar arteries and movse aorta. [C $a^2$$^{+}$]$_{i}$ was recorded by microfluorimeter using Fura-2/AM in EC. No change in contractility was recorded by the increase in [ $K^{+}$]$_{0}$ from 6 to 12 mM in conduit artery such as rabbit carotid artery. whereas resistant vessels, such as basilar and branches of superior mesenteric arteries (SMA), were relaxed by the increase. In basilar artery, the relaxation by the increase in [ $K^{+}$]$_{0}$ to from 1 to 3 mM was bigger than that by the increase from 6 to 12 mM. In contrast, in branches of SMA, the relaxation by the increase in [ $K^{+}$]$_{0}$ to from 6 to 12 mM is bigger than that by the increase from 1 to 3 mM. $Ba^2$$^{+}$ (30 $\mu$M) did not inhibit the relaxation by the increase in [ $K^{+}$]$_{0}$ from 1 to 3 mM but did inhibit the relaxation by the increase from 6 to 12 mM. In the mouse aorta without the endothelium or treated with $N^{G}$_nitro-L-arginine (30 $\mu$M), nitric oxide synthesis blocker, the increase in [ $K^{+}$]$_{0}$ from 6 to 12 mM did not change the magnitude of contraction induced either norepinephrine or prostaglandin $F_2$$_{\alpha}$. The increase in [ $K^{+}$]$_{0}$ up to 12 mM did not induce contraction of mouse aorta but the increase more than 12 mM induced contraction. In the mouse aorta, EDR was completely inhibited on increasing [ $K^{+}$]$_{0}$ from 6 to 12 mM. In cultured mouse aorta EC, [C $a^2$$^{+}$]$_{i}$ , was increased by acetylcholine or ATP application and the increased [C $a^2$$^{+}$]$_{i}$ , was reduced by the increase in [ $K^{+}$]$_{0}$ reversibly and concentration-dependently. In human umbilical vein EC, similar effect of extracellular $K^{+}$ was observed. Ouabain, a N $a^{+}$ - $K^{+}$ pump blocker, and N $i^2$$^{+}$, a N $a^{+}$ - $Ca^2$$^{+}$ exchanger blocker, reversed the inhibitory effect of extracellular $K^{+}$. In resistant arteries, the increase in [ $K^{+}$]$_{0}$ relaxes vascular smooth muscle and the underlying mechanisms differ according to the kinds of the arteries; $Ba^2$$^{+}$-insensitive mechanism in basilar artery and $Ba^2$$^{+}$ -sensitive one in branches of SMA. It also inhibits [C $a^2$$^{+}$]$_{i}$ , increase in EC and thereby EDR. The initial mechanism of the inhibition may be due to the activation of N $a^{+}$ - $K^{+}$pump. activation of N $a^{+}$ - $K^{+}$pump.p.p.p.

Purpose : This study aimed to compare and evaluate between the efficiency of two respective devices, 3D-bolus and step-bolus when the devices were used for the treatment of patients whose chest walls were required to undergo the electron beam therapy after the surgical procedure of modified radical mastectomy, MRM. Materials and Methods : The treatment plan of reverse hockey stick method, using the photon beam and electron beam, had been set for six breast cancer patients and these 6 breast cancer patients were selected to be the subjects for this study. The prescribed dose of electron beam for anterior chest wall was set to be 180 cGy per treatment and both the 3D-bolus, produced using 3D printer(CubeX, 3D systems, USA) and the self-made conventional step-bolus were used respectively. The surface dose under 3D-bolus and step-bolus was measured at 5 measurement spots of iso-center, lateral, medial, superior and inferior point, using GAFCHROMIC EBT3 film (International specialty products, USA) and the measured value of dose at 5 spots was compared and analyzed. Also the respective treatment plan was devised, considering the adoption of 3D-bolus and stepbolus and the separate treatment results were compared to each other. Results : The average surface dose was 179.17 cGy when the device of 3D-bolus was adopted and 172.02 cGy when step-bolus was adopted. The average error rate against the prescribed dose of 180 cGy was -(minus) 0.47% when the device of 3D-bolus was adopted and it was -(minus) 4.43% when step-bolus was adopted. It was turned out that the maximum error rate at the point of iso-center was 2.69%, in case of 3D-bolus adoption and it was 5,54% in case of step-bolus adoption. The maximum discrepancy in terms of treatment accuracy was revealed to be about 6% when step-bolus was adopted and to be about 3% when 3D-bolus was adopted. The difference in average target dose on chest wall between 3D-bolus treatment plan and step-bolus treatment plan was shown to be insignificant as the difference was only 0.3%. However, to mention the average prescribed dose for the part of lung and heart, that of 3D-bolus was decreased by 11% for lung and by 8% for heart, compared to that of step-bolus. Conclusion : It was confirmed through this research that the dose uniformity could be improved better through the device of 3D-bolus than through the device of step-bolus, as the device of 3D-bolus, produced in consideration of the contact condition of skin surface of chest wall, could be attached to patients' skin more nicely and the thickness of chest wall can be guaranteed more accurately by the device of 3D-bolus. It is considered that 3D-bolus device can be highly appreciated clinically because 3D-bolus reduces the dose on the adjacent organs and make the normal tissues protected, while that gives no reduction of dose on chest wall.

Purpose: Helical Tomotherapy allows only coplanar beam delivery because it does not allow couch rotation. We investigated a method to introduce non-coplanar beam by tilting a patient's head for Tomotherapy. The aim of this study was to compare intrafractional movement during Tomotherapy between coplanar and non-coplanar patient's setup. Materials and Methods: Helical Tomotherapy was used for treating eight patients with intracranial tumor. The subjects were divided into three groups: one group (coplanar) of 2 patients who lay on S-plate with supine position and wore thermoplastic mask for immobilizing the head, second group (non-coplanar) of 3 patients who lay on S-plate with supine position and whose head was tilted with Variable Axis Baseplate and wore thermoplastic mask, and third group (non-coplanar plus mouthpiece) of 3 patients whose head was tilted and wore a mouthpiece immobilization device and thermoplastic mask. The patients were treated with Tomotherapy after treatment planning with Tomotherapy Planning System. Megavoltage computed tomography (MVCT) was performed before and after treatment, and the intrafractional error was measured with lateral(X), longitudinal(Y), vertical(Z) direction movements and vector ($\sqrt{x^2+y^2+z^2}$) value for assessing overall movement. Results: Intrafractional error was compared among three groups by taking the error of MVCT taken after the treatment. As the correction values (X, Y, Z) between MVCT image taken after treatment and CT-simulation image are close to zero, the patient movement is small. When the mean values of movement of each direction for non-coplanar setup were compared with coplanar setup group, X-axis movement was decreased by 13%, but Y-axis and Z-axis movement were increased by 109% and 88%, respectively. Movements of Y-axis and Z-axis with non-coplanar setup were relatively greater than that of X-axis since a tilted head tended to slip down. The mean of X-axis movement of the group who used a mouthpiece was greater by 9.4% than the group who did not use, but the mean of Y-axis movement was lower by at least 64%, and the mean of Z-axis was lower by at least 67%, and the mean of Z-axis was lower by at least 67%, and the vector was lower by at least 59% with the use of a mouthpiece. Among these 8 patients, one patient whose tumor was located on left frontal lobe and left basal ganglia received reduced radiation dose of 38% in right eye, 23% in left eye, 30% in optic chiasm, 27% in brain stem, and 8% in normal brain with non-coplanar method. Conclusion: Tomotherapy only allows coplanar delivery of IMRT treatment. To complement this shortcoming, Tomotherapy can be used with non-coplanar method by artificially tilting the patient's head and using an oral immobilization instrument to minimize the movement of patient, when intracranial tumor locates near critical organs or has to be treated with high dose radiation.

Purpose: This study examined changes in the position of the heat and lungs depending on the patient's breathing method during left breast cancer radiotherapy and used treatment plans to compare the resulting radiation dose. Materials and methods: The participants consisted of 10 patients with left breast cancer. A CT simulator(SIMENS SOMATOM AS, Germany) was used to obtain images when using three different breathing methods: free breathing(FB), deep inspiration breath hold(DIBH with Abches, DIBH), inspiration breath hold(IBH with CPAP, CPAP). A Ray Station(5.0.2.35, Sweden) was used for treatment planning, the treatment method was volumetric modulated arc therapy (VMAT) with one partial arc of the same angle, and the prescribed dose to the planning target volume (PTV) was a total dose of 50Gy(2Gy/day). In treatment plan analysis, the 95% dose (D95) to the PTV, the conformity index(CI), and the homogeneity index (HI) were compared. The lungs, heart, and left anterior descending artery (LAD) were selected as the organs at risk(OARs). Results: The mean volume of the ipsilateral lung for FB, DIBH, and CPAP was 1245.58±301.31㎤, 1790.09±362.43 ㎤, 1775.44±476.71 ㎤. The mean D95 for the PTV was 46.67±1.89Gy, 46.85±1.72Gy, 46.97±23.4Gy, and the mean CI and HI were 0.95±0.02, 0.96±0.02, 0.95±0.02 and 0.91±0.01, 0.90±0.01, 0.92±0.02. The V20 of Whole Lung was 10.74±4.50%, 8.29±3.14%, 9.12±3.29% and The V20 of the ipsilateral lung was 20.45±8.65%, 17.18±7.04%, 18.85±7.85%, the Dmean of the heart was 7.82±1.27Gy, 6.10±1.27Gy, 5.67±1.56Gy, and the Dmax of the LAD was 20.41±7.56Gy, 14.88±3.57Gy, 14.96±2.81Gy. The distance from the thoracic wall to the LAD was measured to be 11.33±4.70mm, 22.40±6.01mm, 20.14±6.23mm. Conclusion: During left breast cancer radiotherapy, the lung volume was 46.24% larger for DIBH than for FB, and 43.11% larger for CPAP than FB. The larger lung volume increases the distance between the thoracic wall and the heart. In this way, the LAD, which is one of the nearby OARs, can be more effectively protected while still satisfying the treatment plan. The lung volume was largest for DIBH, and the distance between the LAD and thoracic wall was also the greatest. However, when performing treatment with DIBH, the intra-fraction error cannot be ignored. Moreover, communication between the patient and the radiotherapist is also an important factor in DIBH treatment. When communication is problematic, or if the patient has difficulty holding their breath, we believe that CPAP could be used as an alternative to DIBH. In order to verify the clinical efficacy of CPAP, it will be necessary to perform long-term follow-up of a greater number of patients.

Food service is the major part of franchise business in Korea, accounting for 69.9% of the brands in the market. As the food service industry becomes mature, many franchisees have struggled to survive in the market. In general, consumers have higher levels of expectation toward service quality of franchised outlets compared that of (non-franchised) independent ones. They also tend to believe that franchisees deliver standardized service at the uniform food price, regardless of their locations. Such beliefs seem to be important reasons that consumers prefer franchised outlets to independent ones. Nevertheless, few studies examined the impact of qualify features of franchisees on customer satisfaction so far. To this end, this study examined the characteristics of various quality features of franchisees in the food service industry, regarding their relationship with customer satisfaction and dissatisfaction. The quality perception of heavy-users was also compared with that of light-users in order to find insights for developing differentiated marketing strategy for the two segments. Customer satisfaction has been understood as a one-dimensional construct while there are recent studies that insist two-dimensional nature of the construct. In this regard, Kano et al. (1984) suggested to categorize quality features of a product or service into five types, based on their relation to customer satisfaction and dissatisfaction: Must-be quality, Attractive quality, One-dimensional quality, Indifferent quality, and Reverse quality. According to the Kano model, customers are more dissatisfied when Must-be quality(M) are not fulfilled, but their satisfaction does not arise above neutral no matter how fully the quality fulfilled. In comparison, customers are more satisfied with a full provision of Attactive quality(A) but manage to accept its dysfunction. One-dimensional quality(O) results in satisfaction when fulfilled and dissatisfaction when not fulfilled. For Indifferent quality(I), its presence or absence influences neither customer satisfaction nor dissatisfaction. Lastly, Reverse quality(R) refers to the features whose high degree of achievement results in customer dissatisfaction rather than satisfaction. Meanwhile, the basic guidelines of the Kano model have a limitation in that the quality type of each feature is simply determined by calculating the mode statistics. In order to overcome such limitation, the relative importance of each feature on customer satisfaction (Better value; b) and dissatisfaction (Worse value; w) were calculated following the formulas below (Timko, 1993). The Better value indicates how much customer satisfaction is increased by providing the quality feature in question. In contrast, the Worse value indicates how much customer dissatisfaction is decreased by providing the quality feature. Better = (A + O)/(A+O+M+I) Worse = (O+M)/(A+O+M+I)(-1) An on-line survey was performed in order to understand the nature of quality features of franchisees in the food service industry by applying the Kano Model. A total of twenty quality features (refer to the Table 2) were identified as the result of literature review in franchise business and a pre-test with fifty college students in Seoul. The potential respondents of our main survey was limited to the customers who have visited more than two restaurants/stores of the same franchise brand. Survey invitation e-mails were sent out to the panels of a market research company and a total of 257 responses were used for analysis. Following the guidelines of Kano model, each of the twenty quality features was classified into one of the five types based on customers' responses to a set of questions: "(1) how do you feel if the following quality feature is fulfilled in the franchise restaurant that you visit," and "(2) how do you feel if the following quality feature is not fulfilled in the franchise restaurant that you visit." The analyses revealed that customers' dissatisfaction with franchisees is commonly associated with the poor level of cleanliness of the store (w=-0.872), kindness of the staffs(w=-0.890), conveniences such as parking lot and restroom(w=-0.669), and expertise of the staffs(w=-0.492). Such quality features were categorized as Must-be quality in this study. While standardization or uniformity across franchisees has been emphasized in franchise business, this study found that consumers are interested only in uniformity of price across franchisees(w=-0.608), but not interested in standardizations of menu items, interior designs, customer service procedures, and food tastes. Customers appeared to be more satisfied when the franchise brand has promotional events such as giveaways(b=0.767), good accessibility(b=0.699), customer loyalty programs(b=0.659), award winning history(b=0.641), and outlets in the overseas market(b=0.506). The results are summarized in a matrix form in Table 1. Better(b) and Worse(w) index indicate relative importance of each quality feature on customer satisfaction and dissatisfaction, respectively. Meanwhile, there were differences in perceiving the quality features between light users and heavy users of any specific franchise brand in the food service industry. Expertise of the staffs was labeled as Must-be quality for heavy users but Indifferent quality for light users. Light users seemed indifferent to overseas expansion of the brand and offering new menu items on a regular basis, while heavy users appeared to perceive them as Attractive quality. Such difference may come from their different levels of involvement when they eat out. The results are shown in Table 2. The findings of this study help practitioners understand the quality features they need to focus on to strengthen the competitive power in the food service market. Above all, removing the factors that cause customer dissatisfaction seems to be the most critical for franchisees. To retain loyal customers of the franchise brand, it is also recommended for franchisor to invest resources in the development of new menu items as well as training programs for the staffs. Lastly, if resources allow, promotional events, loyalty programs, overseas expansion, award-winning history can be considered as tools for attracting more customers to the business.

1. 연구배경 사상체질의학(四象體質醫學)을 창시하여 개인(個人)의 차별성(差別性)을 강조한 동무(東武) 이제마(李濟馬)는 양생(養生)의 방법(方法)에서도 체질별(體質別) 요법(療法)을 말하고 있는데 체질별(體質別)로 과소지장(過小之臟)의 기능(機能)이 정상적(正常的)으로 이루어지는 상황을 완실무병(完實無病)의 조건으로 제시(提示)하였고 이를 위한 수단(手段)으로 성정(性情)과 함께 약물(藥物), 식품(食品) 등을 이용하였다. 특히 식이요법(食餌療法)에 있어서도 체질(體質)에 따른 구별(區別)의 필요성(必要性)을 말하고 있는데 식품(食品)이라 하더라도 그 음식(飮食)을 섭취하여 과대(過大)한 장기(臟器)의 기능(機能)은 유제(柳制)하고 과소(過小)한 기능(機能)은 보완(補完)받음으로써 불균형(不均衡)을 조정(調整)한 것이다. 당뇨병의 식단 작성은 평생동안 열량(熱量)과 영양소(營養素) 필요치(必要置)을 맞출 것을 권장하고 당뇨병학회에서 편집한 식품교환표(食品交換表)를 사용(使用)하는 것이 일반적(一般的)인데 식품교환표(食品交換表)는 많은 식품(食品)들중에 같은 영양소를 가진 식품(食品)들을 한 그룹으로 묶어 환자(患者)의 기호(嗜好)에 따라 교환(交煥)해 가면서 먹을 수 있도록 고안(考案)한 것이니 이에 지시한 수량(數量)만 섭취해도 저(低)cal식(食)으로 관양(管養)의 균형(均衡)이 잘 이루어진다. 본 연구는 체질별로 이로운 식품표에 근거하여 식이요법(食餌療法)이 특히 강조되고 하루 섭취열량이 제한되는 성인병중의 하나인 당뇨병(糖尿病)의 식단(1800kcal)을 식단작성법에 따라 구성(構成)하여 몇가지 예를 제시해 보았다. 구체적으로 태음인(太陰人), 소음인(少陰人), 소양인(少陽人)의 당뇨 환자 1800kcal에 대한 식단을 구성하여 제시했는데 즉, 태음인(太陰人)의 식단은 태음인(太陰人)에 유리(有利)한 식품(食品)들로 구성하고 해(害)로운 식품(食品)들은 제외시키는 방법(方法)을 이용하였다. 이 식단은 다분히 이론적(理論的)인 식단으로 임상(臨床)에 이용(利用)하여 본 바는 없으나 동량(同量)의 열량(熱量)을 섭취(攝取)하더라도 체질(體質)에 적합(適合)한 식품(食品)으로 구성된 식사(食事)가 각 체질의 섭생(攝生)에 더 유리(有利)하지 않올까 하는 단순(單純)한 사고(思考)에 바탕을 둔 것이다. 2. 연구방법 1) 후세가(後世家)가 주장(主張)한 체질별(體質別) 식품(食品) 분류(分類)를 종합, 정리한 체질별(體質別) 식품표(食品表)를 제시한다. 박석언의 동의사상대전, 박인상의 동의사상요결, 송일병의 알기 쉬운 사상의학, 홍순용의 사상진료보원, 홍순용, 이을호의 사상의학원론에서 체질별로 유익한 식풍을 조사하여 곡류, 과일류, 채소류, 어패류, 육류로 분류하여 살펴본다. 2) 당뇨병(糖尿病) 식이요법의 식단 작성법의 개요(槪要)를 제시한다. 3) 1)의 체질별(體質別) 식품표(食品表)로 태음인(太陰人), 소음인(少陰人), 소양인(少陽人)의 당뇨 식단 1800kcal을 작성해 제시(提示)한다. 체질별(體質別)로 유익(有益)한 식품(食品)은 1)의 식품표에 근거(根據)하고 체질별(體質別)로 해(害)로운 식품(食品)은 노정우(盧正祐), 한동석(韓東錫)의 주장에 근거(根據)한다. 3. 결과 체질별(體質別) 식품표(食品表)는 후세가의 연구를 종합하여 제시(提示)하였고, 식품(食品)을 분류(分類)한 후(後) 약명(藥名)과 성미(性味), 귀경(歸經)을 찾아 도표화 하였다. 체질별 식품들은 대부분 소음인(少陰人)의 경우 신감(辛甘) 온열(溫熱)하며 비위(脾胃)로 귀경(歸經)하고 태음인(太陰人)의 경우 감신(甘辛) 온열(溫熱)하며 폐간(肺肝)으로 귀경(歸經)하고 소양인(少陽人)의 산고(酸苦) 양한(凉寒)하고 신(腎)으로 귀경(歸經)함이 우세(優勢)함을 알 수 있다. 즉, 체질적으로 양성(陽性)인 소양인(少陽人)은 식품의 성질이 음성(陰性)인 것이 유리(有利)하고 체질적으로 음성(陰性)인 태음인(太陰人), 소음인(少陰人)은 식품의 성질이 양성(陽性)인 것이 유리(有利)하다. 다양한 식품(食品)을 섭취하고자 하는 환자의 욕구(慾求)에 맞추면서도 식품교환의 범위를 체질별로 유익한 식품들로 제한하여 동일(同一)한 열량(熱量)의 식단이라도 체질에 맞는 식품으로 차별성(差別性)을 두었는데 식단의 작성은 전문 영양사의 의견을 거쳤다. 제시된 식단은 다소 이론적(理論的)으로 작성(作成)된 단계이고 임상적(臨床的) 검증을 거친 바 없으나 활용하기에 따라 실용성을 얻을 수 있으리라 본다. <식단예> 태음인의 식단: 곡류 : 콩, 율무, 밀가루, 밀, 수수, 들깨, 고구마, 땅콩, 기장, 옥수수, 두부, 설탕등 태음인에 유리한 식품으로 교환한다 어때류 : 우렁이, 대구, 조기, 민어, 청어, 오정어, 낙지, 미역, 김, 다시마등으로 교환한다 육류 : 소고기, 우유등으로 교환한다 과일류 : 밤, 배, 호도, 은행, 잣, 살구, 매실, 자두등으로 교환한다 채소류 : 무우, 도라지, 연근, 토란, 마, 고사리, 더덕, 목이버섯, 송이버섯, 석이버섯등으로 교환한다 해로운 음식 : 닭, 돼지, 모밀, 배추, 사과, 염소고기, 조개, 계란, 곳감, 커피등은 피한다 * 아침 ; 콩나물죽, 대구포묶음, 우령이무침, 갓김치, 우유, 자두 점심 ; 기장밥, 콩나물두부찌게, 장어양념구이, 도라지나물, 열무김치, 배 저녁 ; 수수밥, 두부명란, 더덕양념구이, 깍두기 * 아침 ; 비빔국수, 토란국, 알타리김치, 두유, 살구주스 점심 ; 율무밥, 낙지전골, 김무생채, 느타리나물무침, 동치미, 귤 저녁 ; 콩밥, 감자북어국, 두부묶음, 열무김치 소음인의 식단: 곡류 : 찹쌀, 좁쌀, 차조, 감자등 소음인에 유익한 식품으로 교환한다 어패류 : 명태, 미꾸라지, 뱀장어, 뱀, 메기등 육류 : 닭, 개, 꿩, 염소, 양, 참새고기등 과일류 : 사과, 귤, 복숭아, 대추등 채소류 : 미나리, 파, 마늘, 후추, 시금치, 양배추, 생강, 고추, 당근, 양파, 감자, 쑥갓등 해로운 음식 : 메밀, 호도, 계란, 고구마, 녹두, 돼지고기, 밤, 배, 배추, 보리, 쇠고기, 수박, 오이, 참외, 팥등은 피한다. * 아침 ; 찰밥, 닭찜, 감자전, 쑥갓나물, 부추김치, 사과 점심 ; 감자밥, 메기매운탕, 명태조림, 미나리, 고들빼기김치, 사과주스 저녁 ; 좁쌀밥, 양배추감자국, 병어양념구이, 연근양념조림, 귤, 인삼차.
