Objectives: Weight control practices are common in combat sport athletes. This study was performed to examine nutrient intakes of male college combat sport athletes (taekwondo, boxing, judo) by weight control (WC) status. Methods: Subjects were male combat sport athletes (n=90) from colleges in Gyeonggi Province. Survey was conducted during 2016. Questionnaire included general characteristics, weight control, and dietary intakes during the period of training, weight control, weigh-in ~ before competition and between competitions. Subjects were grouped into high- and normal WC groups. T-test, ${\chi}^2-test$, Fisher's exact test and ANCOVA were used to analyze the data. Results: During training, energy intake was 75.4% of EER and C:P:F ratio was 57.5:13.9:28.7. Iron and zinc intakes were different by WC groups (p<0.05). During weight control, energy intake was 44.7% of EER in normal WC and 30.5% in high WC group (p<0.05). C:P:F ratio was 69:11.1:19.5, and ratio from protein and fat was lower in the high WC group (p<0.05). Most nutrient intakes during weight control were less than 50% of 2015 KDRIs (RNI or AI), and intakes including thiamin (p<0.01), vitamin A, riboflavin, niacin, folate, calcium, potassium and zinc (p<0.05) were significantly lower in the high WC. Energy intake after weighing before the competition was 1,315 kcal, and energy (kcal/kg BW, p<0.05) and carbohydrate intakes (g/kg BW, p<0.01) were significantly higher in the high WC group. Energy intake between competitions was 691.1 kcal, with no difference by the WC group. Conclusions: Nutrients intakes of combat sport athletes were inadequate. Dietary intakes during weight control were much below than the KDRIs, especially in the high WC group. It is needed to develop nutrition education programs for combat sport athletes to avoid severe energy restrictions and to apply specific dietary guides to each period of training and weight control.

Objective: In dryland areas of China, alfalfa hay (AH) is a possible substitute for concentrate feed for beef cattle. To evaluate the potential benefits of this substitution, we studied the effect of the ratio of AH intake to total dry matter (DM) intake on average daily body-weight gain (ADG), dietary energy utilization status, and economic benefit in Gansu province. Methods: In each of two feeding trials in 2016 (trial 1 [T1], July 3 to 17; trial 2 [T2], August 15 to September 23), crossbred male Simmental calves were allocated to low AH (LA), medium AH (MA), and high AH (HA) feeding groups (n = 4 per group). The target ADG was set as 1 kg for both trials. In a one-way-layout design based on conventional feeding practices in the province, calves received diets containing the different AH amounts, with a constant ratio of corn stover:total DM and decreasing rations of concentrate feed proportional to the increase in AH. Calves in T1 received AH at 15% (T1-LA), 23% (T1-MA), or 31% (T1-HA) of their dietary DM allowances; those in T2 received 9% (T2-LA), 24% (T2-MA), or 34% (T2-HA) AH. Results: Among the T1 groups, both ADG and economic benefit were highest in T1-LA; whereas in T2, they were higher in the T2-LA and T2-MA groups than in T2-HA. Energy digestibility did not significantly differ among the groups in either trial. The dietary AH inclusion ratios of 14% in the warm season and 8% to 21% in the cool season appeared to yield optimal ADG, metabolizable energy intake, and economic benefit. Conclusion: Low-level inclusion of AH, ranging from 8% to 21%, is a practical approach for beef cattle feeding. This modified feeding regimen likely will promote increased growth performance during the fattening stage of beef steers in dryland areas of Gansu province, China.

Objectives: The purposes of this study were to compare the degree of sodium reduction practice and estimate sodium intake by salty food preference. Methods: Sodium reduction practices, salty food preferences and estimated sodium intake were surveyed for restaurant owners (n = 80), employees (n = 82) and customers (n = 727) at the restaurants participating in the sodium reduction project in Daegu, Korea. Estimated sodium intake was performed by examining sex, age, body mass index (BMI), salty eating habit and dietary behaviors. Results: The degree of sodium reduction practice was significantly higher in salinity meter use (P < 0.001), low salt seasonings (P < 0.001) and efforts to make the foods as bland as possible overall (P < 0.001) in the restaurants participating in sodium reduction project than in homes (P < 0.001). The degree of sodium reduction practice appeared lower in the high salty food preference group than in the low-preference group in such items as efforts to make the foods as bland as possible overall (P < 0.05) and washing the salty taste and then cooking (P < 0.05). The high-preference group showed high-salt dietary behavior, including eating all the soup until nothing was left (P < 0.05) more than the low-preference group, but low-salt dietary behavior included checking the sodium content in processed foods (P < 0 .0 5) less than the low-preference group. The high-preference group was higher in the soup and stew intake frequency than the low-preference group (P < 0.05) and much lower in nuts (P < 0.05) and fruits (P < 0.05) intake frequency. The high-preference group had a higher salty eating habit (P < 0.05), salty taste assessment (P < 0.05) and estimated sodium intake (P < 0.05) than the low-preference group. Conclusions: The present study showed that the salty food preference was strongly associated with lower sodium reduction practice and higher estimated sodium intake.

병원급식의 관능적인 품질, 특히 적온 관리 실태를 평가하기 위해, 서울시내 소재한 종합병원 20개 병원의 급식제도, 식품운반체계 조사 및 식품생산과정 중 소요시간-온도상태를 조사하였다. 또한 대부분의 병원들이 중앙배선화 되어가는 현시점에서 중앙 및 병동 배선의 장.단점을 비교.분석하기 위하여 두 가지 배선방법을 함께 실시하는 H병원을 대상으로 조사하였고, H병원의 특수한 상황을 배제한 보편적인 실태 비교를 위해 H병원과 병상규모가 유사한(360~520병상) 7개 병원(병동배선 : 4, 중앙배선 : 3)의 배선방법을 비교하여 다음과 같은 결과를 얻었다. 1. 조사대상 20개 병원의 노동관리 실태를 조사한 결과, 병상당 종업원 수를 외국과 비교했을 때 현저히 적었으며, 주당노동시간은 미국의 경우보다 2배 많았다. 또한 사용하는 급식제도는 모두 전통적인 급식제도를 이용했고, 식품운반체계는 최근 1~2년 내에 대부분의 병원들이 중앙배선화 되어 현재 중앙배선 실시 병원은 60%에 달하였으며, 35%가 중앙배선으로 이행해 가는 과도기에 있었고, 단지 5%만이 병동배선을 실시하고 있었다. 그러나 전통적인 급식제도와 중앙배선체계의 단점인 적온관리를 위한 기기 도입을 통해 특별한 배려를 하는 병원은 단지 3개 병원에서 일부 음식에 제한되어 실시되고 있는 실정이었다. 2. 서울시내에 소재한 20개 종합병원에서 제공되는 밥, 국, 육찬(또는 어찬)의 소요시간-온도상태를 조사한 결과, 병동배선 실시 병원의 I, II group의 국과 III group의 밥만이 미각기준온도를 만족시키며, 나머지는 모두 미달하는 수준이었다. 특히 조리후 급식까지 장시간 동안 방치되는 육찬 또는 어찬의 경우는 최저 99.1분에서 최고 199.1분까지 소요되어 급식온도 는 $20.6^{\circ}C$에서 $25.7 ^{\circ}C$로 미각 만족 온도에 크게 미달하는 온도로 급식되고 있었다. 또한 중앙배선방법을 이용하는 병원은 밥의 경우 $^45.3{\circ}C$~52.9$^{\circ}C$, 국의 경우 $43.1^{\circ}C$~ $54.0^{\circ}C$의 범위로 급식되었고, 병동배선을 이용하는 병원도 특별한 적온관리의 배려가 없는 III group 은 55.8$^{\circ}C$로 미각기준온도인 밥 : $65^{\circ}C$, 국 : $70^{\circ}C$에 미달된 것으로 나타났다. 그리고 급식당시의 온도에 영향을 미치는 변수들의 상관관계를 분석한 결과는 중앙 배선시 정량후 급식까지 소요시간이 -.78로 가장 높게, 병동배선의 경우는 정량시 온도가 .61로 가장 높게 나타났다. 3. 중앙배선 및 병동배선 비교연구 결과 중 소요시간-온도상태의 비교연구 결과, 병동배선이 유의적으로 높은 온도를 나타냈으나, 두 배선방법 모두 미각 만족온도에는 미달되는 수준이었다. H병원에서 조사한 환자수응도 비교연구 결과는 배선방법간에 유의적인 차이가 없었다. 또한 노동가 연구 결과 H병원의 경우 중앙배선시 병동배선에 비해 노동시간이 21.0% 절약되었고, 노동임금도 17.9%가 낮았으며, 서울시내 7개 병원의 조사결과는 중앙배선시 병동배선보다 노동시간이 38.4%, 노동임금이 21.35%가 절약된 것으로 집계되었다. 즉 중앙배선을 실시하는 경우 노동임금이 절약되는 잇점이 있으나, 급식되는 온도는 병동배선시보다 유의적으로(P<.01) 낮게 나타나 효과적인 적온관리를 위한 적절한 배려가 절실히 요청된다.

Our current food hygiene law mandates nutrition label (NL) for the special nutrition foods, health support foods, instant foods, and foods with certain nutrient emphasized note, only. Currently more processed foods are bearing nutrition labels though the format is quite inconsistant. This study examined the status on current nutrition labeling practices for the processed foods that are retailed in the supermarket. The obtained information was assessed in the aspects of numerical data presentation on nutrients content, descriptive terms, health claim, and the format. The results are summarized as follows. 1) Foods with NL are limited to the food category specified by current hygiene law while voluntary nutition labeling is few. 2) Descriptive terms such as free, low, and sufficient are not substantiated with quantitative data. The efficacy of microelements which has not been clalified yet are overemphasized but major nutrients are ignored. 3) The regulations for the descriptive terms are set on the base of the nutrient content per 100g or 100ml under current nutrition labeling act. It would mislead consumers thus the definition for these descriptor be better set on the unit of the amount of food customary eaten at one time. For this the standard serving size should be set officially. 4) Quantitative nutrition information given on food products is difficult to compare because of the lack in formality. The title of NL, load and kinds of nutritents, order of nutrients listed, the unit of expression, RDA comparision, and reference RDA are inconsistant among the foods similar in dietary property. Uniform format is needed to give NL the credibility and usefulness. Proividing nutrition information to the consumers with NL is a worldwide practice though its efficacy has been controversial. Under newly legistered health promotion law in Korean nutrition education is esxpected to take part in to improve national nutrition condition and NL would education is expected to take part in to improve national nutrition condition and NL would be a potent tool for public nutritions education. It appears to be the time to mandate NL to all the processed foods in the market. The result of present study would initiate further consumer experiments related to NL. Various interest groups such as food and nutrition professions, public health organizations, government regulatory agencies, food producers and marketers, and consumer groups need to particepate and communicate for the legislation of NL and the development of NL format.

본 연구는 체중조절 관련 행위의 실천실태 파악과 실천내용에 따라 한국인의 식이섭취 양상에 차이가 있는지 여부를 규명해 보기 위해 수행되었다. 1998년 국민건강.영양조사의 대상이 되었던 20세이상 성인 7370명의 체중관련 실천행위와 그들의 식품 및 영양소섭취 자료가 분석에 이용되었다. 체중관련 실천 행위로는 체중감량 노력, 체중증가 노력, 노력 안 함 등의 실천행위와 체중감소 노력이유, 체중감소 노력시 사용한 방법 등이 조사되었고 자료수집은 설문지를 이용한 면접 조사를 통해 수행되었다 식품 및 영양소 섭취조사는 24시간 회상법이 이용되었다. 분석결과 한국인의 32%가 체중조절 행위를 실천하고 있는 것으로 나타났으며 이는 미국등의 실천 수준보다 훨씬 낮은 수준이었다. 이들 실천 양상에는 남녀간의 차이가 있어 체중조절 실천 남성의 60%가 체중감소 노력을 하고 있으며 40%는 체중증가 노력을 하고 있어 체중감소노력자가 체중증가노력자의 1.5배였다. 반면 여성 체중조절 실천자중 줄이려는 노력자는 전체 노력자의 88%로써 줄이려는 노력자 12%의 7배로 나타났다. 체중조절 노력에 따른 식품 및 영양소 섭취양상은 체중감소 노력을 하는 대상자가 남녀 모두 늘리려는 노력을 하는 사람들보다는 곡류 등 대부분의 식품군에서 낮은 섭취 수준을 보이나 아무 노력도 하지 않는 군보다는 높은 섭취 수준을 보여주고 있다. 이러한 식품 섭취 결과는 영양소섭취 양상에 그대로 반영되어 줄이려는 노력군의 에너지 단백질 지방 등 대부분의 영양소의 섭취가 노력하지 않는 군보다 높게 나타나 이들이 궁극적 목적인 체중감량에 성공할 수 없었을 가능성을 본 연구 결과는 시사하고 있다 이러한 격과는 체중 감량 노력 대상자의 대부분이 체중감량이 필요한 비만인이나 질병을 앓고 있는 대상자라는 배경 때문으로 간주된다. 그러므로 비만인들이 건강하지 못한 오래된 식습관을 극복하지 못한 결과로 사료되어 성인기 이전 성장기에 올바른 식습관에 대한 영양교육이 성인 비만의 예방과 치료에 중요함을 본 연구 결과는 시사하고 있다.

The purpose of this study was to examine the effects of food safety management support in the Center for Children's Foodservice Management (CCFSM) on foodservice facilities for children in Busan area. We assessed the status of hygiene and safety practices of institutional and non-institutional foodservice on a quarterly basis by using an inspection checklist for food hygiene and safety developed by dieticians from February to December in 2013. The subjects were 103 children's foodservices, including 37 institutional and 66 non-institutional foodservices. Inspection checklist consisted of nine categories with 39 checklists; general characteristics, personal hygiene, ingredient control, menu planning, cooking processing control, serving management, washing, disinfection and storage control, and environment and safety management. The average score of each field (pre-supporting/post-supporting) in institutional foodservice was 0.56/0.92 for personal hygiene, 0.55/0.87 for ingredient control, 0.76/0.97 for menu planning, 0.53/0.89 for processing control, 0.27/0.67 for serving management, 0.47/0.91 for washing, disinfection and storage control, and 0.61/0.91 for environment management and 0.64/0.94 for safety management. In non-institutional foodservice, the average score of each field (pre-supporting/post-supporting) was 0.49/0.80 for personal hygiene, 0.52/0.75 for ingredient control, 0.78/0.97 for menu planning, 0.42/0.76 for processing control, 0.32/0.61 for serving management, 0.57/0.88 for washing, disinfection and storage control, and 0.46/0.82 for environment management and 0.73/0.88 for safety management. The average scores of all categories (pre-supporting/post-supporting) were 0.57/0.91 in institutional foodservice and 0.53/0.82 in non-institutional foodservice. The effects of management support in CCFSM on institutional foodservice were higher than those of non-institutional foodservice. Based on these results, we found that management support in CCFSM on foodservice facilities for children had a significantly positive effect on status of hygiene and safety practice regardless of foodservice facility size.

This study was carried out to investigate the relationship between the food and nutrient intake status and eating-out practices of college students. A dietary survey of 361 subjects living in urban areas was conducted by using a 3-day diet record method. The average ages of the male and female subjects were 22.0 and 20.6 years old, respectively. Monthly personal expenses of the male and female students were 316,517 won and 296,888 won, respectively. 43.1% of the male and 50.8% of the female students used between one-quarter and one-half of their monthly personal expenses for eating out. Sixty-five percent of the total subjects ate out more than five times a week The average daily total food intake was 1630.7g in the males and 1453.9g in the females. The average percentage of total food intake from eating out (by weight) was 60.6% in the males and 56.2% in the females; foods eaten out were mainly potatoes, meats, processed foods, and beverages. It was found that 40-65% of daily total nutrient intake came from food eaten out. When they ate out, the male students ate slightly higher amounts of protein, fat and vitamin B1, while the female students ate relatively higher amounts of animal protein, fat, vitamin A and cholesterol. The more the subjects ate out, the more the quantity of total food intake increased. This increase resulted from high intakes of beverages and processed foods in the males, while the increase was from total plant foods, mushrooms, beverages, and milk and dairy products, in the females. The dietary variety score (DVS) was significantly increased in the female subjects when they ate out more than once a day; otherwise, the DVS was not significantly different between any of the male and female groups. The intakes of energy, and of many nutrients such as protein, fat, carbohydrates, calcium, phosphorus, iron, potassium and cholesterol, were increased when the female subjects ate out more than twice a day. The mean adequacy ratio (MAR) was at its highest level of 0.65 in the males when they ate out less than once a day, and at its highest level of 0.67 in the females when they ate out more than twice a day.

Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 ${\leq}$ T-score ${\leq}$ 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin $B_2$ (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.
