The aims of this study were to investigate some macrominerals (Na, Ca, P, K, Mg) in 207 beverages, 19 liquid teas, and 24 liquid coffees. The samples were digested by microwave and determinations of macrominerals were carried out by an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). The elements, listed in order of mean value of macromineral content, were potassium $208.4{\pm}298.2mg/L$ ($72.2{\pm}169.8mg/container$)> calcium $89.0{\pm}161.0mg/L$ ($26.0{\pm}57.7mg/container$)> sodium $71.2{\pm}75.0mg/L$ ($20.9{\pm}27.9mg/container$)> phosphorus $55.6{\pm}91.9mg/L$ ($17.9{\pm}33.8mg/container$)> magnesium $6.1{\pm}18.4mg/L$ ($2.4{\pm}10.1mg/container$). All 250 samples contained sodium and potassium, and the detection rate of calcium, phosphorus and magnesium was 88.4%, 93.2%, and 20.4%. The mean ratio of phosphorus to calcium in beverages, liquid teas, and liquid coffees was $4.2{\pm}16.0$ (ND~164.4), and sports drinks showed the highest mean ratio ($48.5{\pm}75.6$) significantly (p<0.05). In case of sodium, detected content exceeding labeling regulations (less then 120%) was observed in 12 samples (5.5%).

The purpose of this study was to investigate the effect of Saengmaeg-san intake on blood lipids and arteriosclerosis index in male tennis players. Seventeen male tennis players enrolled in university were assigned to a Saengmaeg-san intake group (n=9) and a placebo control group (n=8) according to whether they took Saengmaeg-san during 4-week high-intensity tennis training. Tennis training was conducted 5 times a week for 4 weeks, and the exercise intensity was performed at 70-90% of the spare heart rate. The intake of Saengmaeg-san was 110ml at a time before breakfast, before, during, during, and after exercise, and after dinner, a total of 7 times, 770ml per day. For all data, mean and standard deviation were used. Two-way repeated measures ANOVA was used to examine the effect of time and treatment, and Pearson's Correlation was used to examine the relevance of differences in blood lipid responses after treatment. As a result of this study, the Saengmaeg-san intake group significantly improved blood lipids (triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol) and arteriosclerosis index, and there was a significant correlation appeared between ∆TG, ∆LDL-C, and ∆TC. As a result, the intake of Saengmaeg-san during high-intensity training of male college student tennis players can have a positive effect on blood lipids and arteriosclerosis index, suggesting that it can be an effective sports drink as an exercise supplement.

We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.

After oral administration of various drinking solutions, the initial absorption rate of water through gastrointestinal tract of the rabbits was evaluated using tritinated water $(^3H_2O)$ as a marker to develop the sports drinking beverage for Korean people. The polynomial curve fitting over 20 min was performed using computer program to obtain the initial absorption rate of water from the tangent line of the fitted equation because initial absorption rate of water was more critical compared to elimination rate during exercise. The amount of water absorbed was increased but a large variation was observed among testing preparations in a small study group $(2{\leq}n{\leq}6)$. The initial absorption rate of water from isotonic sports drinking beverages was statistically significant when compared to hypertonic cola but was not significant when compared to hypotonic solutions (potable water and barley water). In case of hypertonic sports dringking beverages (i.e. Takeda), initial absorption rate of water was not improved and efficient when compared to other isotonic sports dringking beverages. The initial absorption rate of water from prescribed isotonic sample solution containing electrolytes, carbohydrates, and vitamins was not statistically significant when compared to other isotonic drinking beverages but showed similar absorption profile. It was obvious that isotonic solutions simultaneously containing electrolytes, vitamins and carbohydrates (sugar and glucose) had a tendency to increase the initial absorption of water compared to hypotonic (potable water and barley water) and hypertonic preparations (orange juice and cola). Although statistical significance of initial absorption rate of water between isotonic sports drinking beverages and hypotonic potable and barley water was not observed, unlike the hypertonic solutions, isotonic sports drinking beverages may aid not only to replenish loss of water, electrolytes and other nutrients during the exercise but also to prevent dehydration and muscle fatigue, resulting in improved physical performance in an exhausted condition.

A low-cost and flexible potassium ion (K⁺) sensor was fabricated through a screen-printed process. Uniform and conformal coating of conductive inks was verified by scanning electron microscopy and optical microscopy measurements. The K⁺-sensors showed a high sensitivity, fast response time, and low detection limit. The sensitivity of K⁺-sensor was similar to that of both mechanically normal and bent states. The K⁺-sensor exhibited a good reproducibility with no hysteresis effect and excellent long term stability. In addition, the K⁺-sensor showed an excellent selectivity for K⁺ concentrations in the presence of other interfering cation ions. Successful measurements of K⁺ concentrations in sports drink samples were demonstrated by comparing K⁺ concentration values from K⁺-sensor to those of using a commercial K⁺-meter.

Objective: Two Korea-mode sport beverages with medicinal herbs added, Saeng Mac San (SMS) and Je Ho Tang (JHT), were developed by the Ginseng Research Group of the Korea Food Research Institute. For their practical usage, we examined their taste tests at rest including sense-analysis (S-A) and preference-inquiry (P-I). Methods: Five beverage-treatments, SMS, JHT and three commercial sport beverages (CSBs) and a control (CON) were offered randomly. Eighty-two subjects under stable control of their taste sense filled out the questionnaires for their S-A and p-I, which were developed by the Exercise Physiology Laboratory of Kyungpook National University. The collected data $(means{\pm}SD)$ were analyzed by repeated measures one-way ANOVA; Tukey' s test was administrated for identification of statistically significant differences (p<0.05). Results: Overall beverage likeability values of SMS and JHT were significantly lower than those of CSBs, JHT lower than CON. Overall flavor values of SMS and JHT were significantly lower than those of CSBs and CON. SMS was similar to CON in the amount of flavor. SMS and JHT were less tart than CSBs and the former was significantly lower than CSBs and CON in four drinkability-related items. Conclusion : SMS rated less than CSBs in tartness and the amount of flavor. JHT was avoided most. Thus, the results indicate that JHT is not fit as a sport beverdge and the overall likeability of SMS must be elevated by way of strengthening its tartness and amount of flavor for practical usage.

Women with the premenstrual dysphoric disorder (PMDD) report increased cravings for certain foods and altered taste preferences ding the premenstrual period. The objective of the present study was to investigate the association of PMDD with luteal phase food cravings, appetite, and taste preferences in 1,078 nurses. Among the 626 nurses who gave valid responses, the prevalence of PMDD and premenstrual syndrome (PMS) was 4.6% (N = 29) and 78.3% (N = 490), respectively. A highly significant increase was observed in the preference for sweet tasting foods during the luteal phase, compared to the follicular phase. Desire for sweet foods during the premenstrual period was significantly different among the three groups, being highest in the PMDD group, lower in the PMS group, and lowest in women with no symptoms. Both the PMDD and PMS groups showed significant increases in preferences for pungent tasting foods during the luteal phase. A repeated measures of analysis of variance on the taste preference data revealed that the desire for sweet tasting foods was significantly greater than for others such as salty, sour, and pungent tastes. A greater proportion of the subjects in the PMDD and PMS groups reported an increase in their total food intake during the luteal phase, compared to those women without premenstrual symptoms. Compared to the PMS group or the women with no symptoms, the PMDD group reported increased intakes of high carbohydrate foods during the luteal phase. The most commonly reported food cravings were for sauteed spicy rice cakes (ddukbokki), or for cold buckwheat noodles mixed in chili pepper sauce. These results indicate that the luteal phase food cravings, appetite and taste preferences change in accordance with the severity of the premenstrual symptoms.

신체를 구성하는 여러 가지 요소 중에서 인간이 일상생활을 하는 데에는 신진대사를 일정하게 유지하기 위한 인체내의 여러 가지 전달물질들이 그 구성에 맞게 역할을 수행하여야 한다. 그러나, 만약 그 구성 비율이 바뀔 때에는 인체 내에 이상이 발생하게 된다. 그 대표적인 예로는 운동을 심하게 하였을 경우 갈증과 근육의 피로감이 몰려오게 되는데 이는 세포내의 이온농도의 변화에 의한 것이며 이때 물, 스포츠 이온 음료 등을 섭취한다. 순간적으로 그 증상이 회복되지는 않지만 신경계 내에서 회복하는데 에는 많은 시간이 소요된다. 생리학, 임상적으로 나트륨과 물은 신진대사에 밀접한 연관이 있다. 인체의 나트륨은 음식물의 섭취량과 나트륨의 생리작용사이의 균형에 좌우된다. 건강한 상태에서 나트륨의 생리적인 손실은 무시할 만 하며 나트륨 생리작용은 음식물의 섭취량과 밀접한 관련이 있다. 칼륨은 단지 전체 신경계 용질의 일부이기 때문에 이것은 세포의 체적과 세포 용질의 삼투현상을 결정하는 주요한 것이다. 더욱더 칼륨은 신진대사 과정의 많은 중요한 변수가 되며, 세포밖의 칼륨은 전체중에 매우 작은 일부이긴 하지만 신경근육 작용에 매우 큰 영향을 준다. 세포안과 밖의 칼륨의 농도 비율은 흥분성 조직내의 막 전위의 주요한 결정요소가 된다. 본연구에서는 세포막 설계 후 시뮬레이션을 통한 정상상태의 세포막 전위의 활동전위 전달 특성과 Na, K의 이온 농도를 변화시킬 경우의 세포막 전위의 활동저위 전달 특성곡선을 비교 관찰하여 운동 생리학적인 신경세포내의 전달특성 메카니즘을 이해, 분석하였다.서의 속도를 최소한으로 줄이면서 스케줄링에 의해 시간 문제를 해결하는 방법을 제시하도록 한다. 이는 기초과학 수준이 높은 북방권 국가들의 과학자들이 주로 활용되고 있다는 점에서도 잘 알 수 있으며 우리의 과학기술 약점을 보완하는 원천으로써 외국인 연구 인력이 대안이 되고 있음을 시사한다. 본 연구에서는 한국 연구 조직에서 일하는 외국인 연구자들의 동기 및 성과에 영향을 미치는 많은 요인들을 확인할 수 있었다. 상관관계, 분산분석, 회귀분석 등을 통해 활용 성과에 미치는 영향 요인들을 도출하였다. 설문 분석을 통하여 동기 및 성과 사이에는 강한 상관관계가 존재하는 것을 확인할 수 있었으며 이는 전통적인 동기 이론들과 부합한다. 대부분의 변수가 동기 및 성과에 동시에 영향을 미치는 것으로 조사되었으며 그중에서도 조직 협력 문화, 외국인 연구자의 의사소통 및 협력성, 외국인 연구자의 연구 능력 관련 변수들 및 연구 프로젝트의 기술수명주기, 외국인 연구자의 기존 기술지식의 흡수 등이 가장 중요한 변수로 나타났다. 이는 우리가 주로 중국 및 러시아 과학자들을 활용하여 상업화하는 외국인 연구인력 활용 패턴과도 일치하는 결과이다. 즉 우호적인 조직문화를 가지고 있는 연구 조직에서, 이미 과학기술 지식을 많이 가지고 있고 연구 능력도 높은 외국인 과학기술자를, 한국에서 기술이 태동 또는 성장하고 있는 연구 분야에서 활용하는 것이 가장 성과가 좋다는 사실을 확인시켜 주고 있다. 국내에서 최초로 수행된 본 연구는 외국인 연구 인력의 활용 성과가 매우 높으며, 우리의 과학기술혁신시스템을 보완하는

This study focused on the park as a space to support the behavior of urban citizens in modern society. Modern city parks are not spaces that play a specific role but are used by many people, so their function and meaning may change depending on the user's behavior. In addition, current online data may determine the selection of parks to visit or the usage of parks. Therefore, this study analyzed the change of behavior in Yeouido Park, Yeouido Hangang Park, and Yangjae Citizen's Forest from 2000 to 2018 by utilizing a time series analysis. The analysis method used Big Data techniques such as text mining and social network analysis. The summary of the study is as follows. The usage behavior of Yeouido Park has changed over time to "Ride" (Dynamic Behavior) for the first period (I), "Take" (Information Communication Service Behavior) for the second period (II), "See" (Communicative Behavior) for the third period (III), and "Eat" (Energy Source Behavior) for the fourth period (IV). In the case of Yangjae Citizens' Forest, the usage behavior has changed over time to "Walk" (Dynamic Behavior) for the first, second, and third periods (I), (II), (III) and "Play" (Dynamic Behavior) for the fourth period (IV). Looking at the factors affecting behavior, Yeouido Park was had various factors related to sports, leisure, culture, art, and spare time compared to Yangjae Citizens' Forest. The differences in Yangjae Citizens' Forest that affected its main usage behavior were various elements of natural resources. Second, the behavior of the target areas was found to be focused on certain main behaviors over time and played a role in selecting or limiting future behaviors. These results indicate that the space and facilities of the target areas had not been utilized evenly, as various behaviors have not occurred, however, a certain main behavior has appeared in the target areas. This study has great significance in that it analyzes the usage of urban parks using Big Data techniques, and determined that urban parks are transformed into play spaces where consumption progressed beyond the role of rest and walking. The behavior occurring in modern urban parks is changing in quantity and content. Therefore, through various types of discussions based on the results of the behavior collected through Big Data, we can better understand how citizens are using city parks. This study found that the behavior associated with static behavior in both parks had a great impact on other behaviors.
