The purpose of this study was to investigate the association between depressive symptoms and dietary inflammatory index(DII) in Korean postmenopausal women. The subjects consisted of 3,947 Korean postmenopausal women from the National Health and Nutrition Examination Survey from 2016~2020. Subjects were classified into quartiles of dietary inflammatory index score. Individuals with high DII scores had poor health habits such as drinking, smoking, lack of physical activity, and skipping meals. The higher the score of the DII, the higher the PHQ-9 score and the depression odds ratio, which are depressive screening tools(p for trend <0.01). Among the anti-inflammatory items, DII, MUFA, PUFA, n-3 fatty acids, and n-6 fatty acids increased the risk of depression as the DII item score increased(p for trend <0.05). As a result of this study, it was found that the dietary inflammatory index was significantly associated with depressive symptoms. The promotion of a healthy diet with anti-inflammatory properties may help to prevent depression in postmenopausal women.

The purpose of this study was to examine the relationship between metabolic syndrome and sugar intake. This study was conducted on adults aged over 19 who participated in the 2013-2016 Korea National Health and Nutrition Examination Survey. Subjects were classified according to the ratio of sugar intake to total energy. We used 24-hour recall survey data to investigate the daily sugar intake. The energy intake ratio from the sugar <20% group had higher % KDRI's of calcium, iron, potassium, vitamin A, riboflavin, and vitamin C than the energy intake ratio from the sugar ≥20% group. The risk of blood pressure level was higher in the ≥20% group than in the <20% group. The highest tertile of sugar intake showed an increased risk of elevated blood pressure level. This study found that increased sugar intake was associated with the risk of metabolic syndrome. It is expected that these results can be used as useful information to prepare basic data for establishing and managing sugar-reducing nutrition policies for the prevention of chronic diseases.

Soseon means a table setting without meat and fish. It seems to have been influenced by Buddhism and is mentioned in Joseon Dynasty records. This study aimed to investigate the use of Soseon and its relationship with Buddhism in Joseon, which emphasized Confucianism and refused Buddhism. This study was conducted on the Joseon Dynasty Annals database and records of royal food literature during the Joseon Dynasty. In Joseon, Soseon was seen in 186 cases and its cases were found during the early days than the late days of the same Dynasty. It was carried out at funerals for subjects and relatives(61.82%). national ceremonies(21.51%), envoy receptions(11.29%), and auspicious ceremony(5.38%). Meat dishes were replaced by tofu, seaweed, rice cakes, and cookies in the Soseon for national rituals. The table setting of Soseon consisted of a main dish, side dishes, and desserts. A comparison of the Soseon table setting between Gilrye and Hyungrye showed Chae, Gaejang and Dasik belonged only Gilrye table setting. The major food was Noodles, Tang, Chae, Yumilgwa, Yugwa, Dasik, rice cakes and fruits. Soseon menu was cooked flour, tofu, seaweed, shiitake, pine nut, sesame oil, honey, etc. Tofu, flour, and seaweed were referred to in the documents in relation to Buddhism. This study shows that the Soseon is a vegetarian diet form in Joseon affected by Buddhism from Goryeo. Therefore, this study is expected to be used as basic data for the study of Buddhist food culture of royal rituals in the Joseon Dynasty.

This study evaluated the dietary habits and dietary quality of the Korean elderly according to muscle strength status. This study was conducted on the elderly aged over 65 years who participated in the 2014-2018 Korea National Health and Nutrition Examination Survey. Subjects were classified into the normal muscle strength group(n=2,000) and the low muscle strength group(n=1,273) according to the handgrip strength. There was a significant difference in general characteristics, diet habits, and health behavior according to the muscle strength status. The normal muscle strength group had a higher total score of KHEI and a subtotal score of 「adequacy」 items. But there was not significant difference in the 「moderation」 items. For the 「balance of energy intake」 items, the normal muscle strength group had a higher subtotal score than the low muscle strength group only in among women. The prevalence of low muscle strength decreased in the highest quartile of the adjusted KHEI total score(p for trend=0.08). As a result of this study, it was found that KHEI was significantly associated with muscle strength. This study result can be used to provide dietary guidelines for the improvement of muscle strength in the elderly based on each item of KHEI and sex.

Radium isotopes were measured together with oceanographical parameters in the southern coastal region of the Korean East Sea during the period of September $2{\sim}8$, 1991. In September, there were various water masses vertically distributed in this region due to formation of strongly seasonal thermoclines. These water masses were characterized by activity of radium isotopes as well as water temperature and dissolved oxygen. Among the water masses, Japan Sea Proper Water(JSPW) below $1^{\circ}C$ had the highest Ra-226 activities but the lowest Ra-228 concentrations. However, Tsushima Surface Water (TSW) above $20^{\circ}C$ in water temperature had the highest Ra-228 which decreased sharply with depth. In TSW, Ra-228 activities were in the range of $194{\sim}270$ dpm/kl, which were approximately 10 times higher than JSPW. Activity ratios(A.R's) of Ra-228/Ra-226 were $1.9{\sim}2.6$ for TSW, $0.7{\sim}1.1$ for Tsushima Middle Water(TMW) of $12{\sim}17^{\circ}C\;to\;0.4{\sim}0.7$ for North Korea Cold Water(NKCW) with $1{\sim}7^{\circ}C$ and below 0.2 for JSPW. The Ra-228/Ra-226 ranged from 0.6 to 0.9 in the cold waters of $2{\sim}6^{\circ}C$, which were observed at depth of $65{\sim}120\;m$ in this study area. Radium isotopes provided a useful means of identifying origins of the cold water which occurred annually at intermediate or bottom layers in the southern coastal zone of the Korean East Sea. By plotting radium isotopes against water temperature, it could be observed clearly that the cold waters between $2{\sim}6^{\circ}C$ did not originate from the mixed water of JSPW and TMW but from NKCW.

Objectives: The aim of this study was to assess how nutrient intakes are related to risk factors for metabolic syndrome according to dietary patterns in the middle-aged adults. Methods: The subjects (n = 187; 47 men, 140 women) consisted of middle-aged adults over 30 years old in Ilsan area. The metabolic syndrome was diagnosed according to the data collected from each subject, including anthropometric measurements and blood analyses. The dietary patterns were derived from the average of two-day dietary intake data. Results: Factor analysis identified three major dietary patterns which were "Meats and alcohol", "Mixed grains, vegetables and fruits", and "Rice, Kimchi and fish & shellfish". The daily intakes of energy, protein, and sodium increased across quartiles of "Meats and alcohol" pattern scores (p < 0.05), whereas the intakes of carbohydrates, potassium, calcium, and fiber increased across quartiles of "Mixed grains, vegetables and fruits" pattern scores (p < 0.001). The "Meats and alcohol" pattern scores were positively correlated with protein and sodium intakes but inversely correlated with carbohydrates, fiber and potassium intakes which were adjusted for age, sex and energy (p < 0.05). The highest quartile pattern score of "Meats and alcohol" pattern had elevated odds ratio of abdominal obesity and metabolic syndrome (p < 0.05). The risk of hypertriglyceridemia decreased in the highest quartile of "Mixed grains, vegetables and fruits" pattern (OR 0.35, 95% CI 0.12-1.00). Conclusions: Our results suggested that reducing the consumption of meat and alcohol along with increasing fruits, vegetables and mixed grains would be helpful for preventing the metabolic syndrome and chronic diseases.

A synoptic survery of chemical characteristics in the last Sea of Korea was carried out at the 11 stations near Ullungdo in November, 1994 on board R/V Tam-Yang. On the basis of the vortical distribution patterns of temperature, salinity and dissolved oxygen, water masses in the study area are divided into five groups; 1) Tsushima Surface Water (TSW), 2) Tsushima Middle Water (TMW), 3) East Sea Intermediate Water (ESIW), 4) last Sea Proper Water (ESPW), 5) Mixed Water (MW). In the vertical profiles of nutrients, the concentrations were very low in the surface layer and increased rapidly near the thermocline. There was a slight decrease in the ESIW and the concentrations were constant with the depth below 300m except dissolved silicate which still increased with depth. Relatively high value of Si/P ratio (25.2) in ESPW, whick is the oldest water mass, suggests that Si is regenerating more slowly compared to other nutrients. The relatively high value of N/P ratio (18.6) in the surface layer might be related to high vertical eddy diffusivity $(K_z)$ of $1.19\;cm^{2}/sec$ and high nitrate upward flux of $103.7\;{\mu}g-at/m^{2}/hr$, compared to the values reported in other areas. Apparent Oxygen Utilization (AOU) was very low in the surface layer and increased in the TMW, but there was a slight decrease in the ESIW. The highest value of AOU occurred in the ESPW. The slpoe of P/AOU was 0.50. The study on the relationship between water masses and nutrient distribution patterns is important in understanding the regeneration processes of nutrients in the polar region of the last Sea.
