This study was designed to investigate the biochemical pollutant marker for diagnosis of marine pollutions by the changes in lipid components of the flounder (Pleuronichthys cornutus) in the Yellow Sea of Korea. Hemoglobin levels in serum of wild flounders in the yellow Sea were significantly lower $(15\~30\%)$ than those of wild flounder in Pohang (control) of the East Sea. Triglyceride (TG) contents in serum of wild flounders in the Yellow Sea were higher $(15\~50\%)$ than those of wild flounder in Pohang. Total and low density lipoprotein (LDL)-cholesterol contents in serum of flounders in the Yellow Sea were significantly higher $(20\~25\%\;and\;15\~35\%,\;respectively)$ than those of wild flounder in Pohang. Atherogenic index (Al) in serum of wild flounders in the Yellow Sea were significantly higher $(10\~60\%)$ than these of wild flounder in Pohang but T-Chol/PL ratios showed almost no change in serum of flounders in the Yellow Sea we examined. These results suggest that near-coastal water as well as neritic water of the Yellow Sea might be affected by pollutant input.

Purpose: To analyze the differences of the Body Mass Index (BMI), blood biochemical indices (TC, TG, HDL, PP2) among college faculty members depending on their life styles and thereupon, provide for some basic data useful for healthcare education. Methods: 163 faculty members were sampled for a questionnaire survey and a medical checkup, both conducted from Jan. 20 to Jan. 26, 2010. Results: First, such blood biochemical indicesas BMI, TG, HDL and PP2 differed significantly depending on gender, while TC, TG and HDL differed significantly depending on age. Second, BMI differed significantly depending on drinking. Third, smokers showed significantly lower BMI and PP2 than non-smokers. Among the smokers, those smoking for 1-10 years showed a significantly lower level of TG. Fourth, those exercising as hard as sweating 3 times a week showed significantly lower BMI, TC and TG. Fifth, BMI was correlated positively with TC and TG, while being correlated negatively with HDL. On the other hand, TC was correlated positively with the TG which was correlated negatively with the HDL which was correlated positively with PP2. Conclusion: In order to prevent chronic diseases and live a healthy life, it must be necessary to control drinking, stop smoking and exercise regularly.

Depression is a disease with an increasing prevalence worldwide, and is highly associated with mortality as well as several diseases such as hypertension. The aim of this study is to discover clinical risk indicators associated with depression in the occupational group of simple labor workers. This study used the Seventh Korean National Health and Nutrition Examination Survey (2016-2018) conducted by the Korea Centers for Disease Control and Prevention. In association between depression and demographic information, age, sex, degree of stress perception, and stress perception ratio indices had a very high statistical association with depression, and education level and marital status were also associated with depression. Obesity indices such as abdominal circumference and body mass index were not associated with depression. Among the blood information, hemoglobin and hematocrit were highly associated with depression, and statistical significance was maintained even in the analysis adjusted for sex and age. The results of this study can be used as information for the prevention and treatment of depression in the occupational group of simple labor workers in the future.

A study investigated the effects of Galla Rhois (GR) on growth performance and diarrhea incidence of postweaning piglets. One hundred 28-day-old piglets were randomly assigned into five experimental groups, which were a basal diet alone (NC), chlortetracycline 0.3 g/kg feed (PC) and supplemented with GR 1.0 g/kg feed (GR 1), GR 2.0 g/kg feed (GR 2), and GR 4.0 g/kg feed (GR 3). After 28 days of administration, final body weight (BW) and feed conversion ratio of PC, GR 2 and GR 3 was significantly different compared to those of NC (p < 0.05). Additionally, the average daily gain (ADG) and average daily feed intake (ADFI) of PC and all groups treated with GR was significantly different compared to those of NC (p < 0.05). Especially, final BW, ADG, ADFI and feed conversion ratio (FCR) of GR 2 and GR 3 were not significant different compared to those of PC. In fecal scores and duration of diarrhea, PC and all groups treated with GR were significantly different compared to NC (p < 0.05). In hematogolical and serum biochemical analysis, there were no significant differences in any of the hematogolical and serum biochemical parameters examined in either NC or all groups treated with GR. The results of this study indicated that GR could be a potential candidate as feed additives for the improvement of growth performance and incidence of diarrhea in piglets.

The incidence of gallbladder polyps are increasing due to the extended use of ultrasonography. Although there are various reports on the risk of gallbladder polyps, there are few studies of the relationships among the presence of metabolic syndrome including serum biochemistry, lifestyle and the development of gallbladder polyps. The aim of this study was to determine association of the presence of metabolic syndrome, including serum biochemistry, with the development of gallbladder polyps in the Korean population. Among the health examination examinees, 596 people, who underwent abdominal ultrasonography from January, 2013 to December 2013, were included in this study. Physical measurements also taken, such as height, weight, blood pressure, waist measurement, and BMI. The general characteristics including age, sex, smoking, and drinking as the related factors were checked. At the same time, various blood tests were performed and the fasting blood sugar was analyzed through blood-gathering to determine the presence of metabolic syndrome. Regarding the factors associated with gallbladder polyps, the results showed that being male, smoking, non-drinking were significantly high. In addition, testing positive for HBsAg and an increasing BMI was apparently higher the group with metabolic syndrome than the non-metabolic syndrome group. The highest predictive factors for gallbladder polyps was being male (1.8 times), followed by metabolic syndrome (2.3 times) and testing positive for HBsAg (2.6 times).

In this paper, we propose a system for analyzing nutrition status based on hierarchical fuzzy inference approach, where the hierarchical fuzzy approach used to analyze the transition process on the nutritional status from an obesity degree, the previous nutritional status, and the eating pattern with an individual. Moreover we discussed about the selection method of fuzzy membership intervals of the next layer to improve the reliability of inference results in hierarchical fuzzy system, where their intervals are modified by using statistical information of the defuzzified results obtained from the previous layer. To show the effectiveness of this system, we evaluated the nutritional status from the information of anthropometric measurement, biochemical test, and INQ on 113 people over the age of 65, and also analyzed their nutritional status.

This study was conducted to assess the biochemical nutritional status of 310 elderly(males: 130, females : 180) residing in Puchon City. Subjects were apparently healthy, home staying and aged over 60. Average height of males and females were 163.2cm and 148.5cm, respectively. Female aged over 80 showed 148.5cm, which was significantly lower than that of group aged 60~69. The rate of moderate obesity for males assessed with BMI($\geq$27) was 7.7%, and 23.4% for females. The hypertension rate assessed by SBP($\geq$160mmHg) was 8.0% and 10.5% for males and females, respectively. The proportion of hypertension with indice of DBP( 95mmHg) was 9.4% and 23.4%. The lower concentration of Hb(males: <13g/dl, females: <12g/dl) occurred in 10.7% for males and 11.7% for females. No one except a few was found with protein deficiency assessed with serum albumin, serum protein and the ratio of urinary nitrogen to creatinin. Twenty five percent of males and 35.2% of females belonged to hypercholesterolemia($\geq$ 240mg/dl). The proportion of elderly whose fasting blood sugar was higher than 140mg/dl was 23.7% and 23.2%.

This study was conducted to evaluate the change of nutritional status and to analyze related factors in hospitalized tuberculosis (TB) patients during their hospitalization. The subjects were 398 men patients (mean age: 47.3 ${\pm}$ 14.4 y) who had hospitalized more than 3 months at TB hospital located in Seoul. The anthropometric and blood biochemical indices were measured, and dietary intakes were assessed. At the time of admission the body weight of subjects was about 76% of the average body weight of Korean men with same age, Body mass index (BMI) of subjects was 18.5 kg/$m^2$, and 53.8% of subjects were under weight status. Average level of blood hemoglobin and hematocrit of subjects was lower than the normal value. After 3 months of hospitalization period, the body weight and body mass index were significantly increased compared to admission by 3.9 kg (7.41%) and 1.4 kg/$m^2$ (7.61%)(p < 0.001), respectively. Blood levels of hemoglobin, hematocrit, albumin, and total protein were also significantly increased after 3 months of hospitalization period compared to admission (p < 0.001). The increment in the body weight and blood indices was significantly higher in below 29 years group than over 60 years group (p < 0.05). The increment in the body weight and body mass index was significantly higher in the under-body weight group compared to the normal-body weight group (p < 0.05). In conclusion the body weight and body mass index of subjects were significantly increased after 3 months of hospitalization period, and the age and body weight of subjects at admission were supposed to influence the degree of change in the nutritional status.

The aim of this study is to survey the frequency of mutans streptococci species and biotypes isolated from dental plaque in Korean children and the relationship between species and biotypes of mutans streptococci and dft index. Dental plaques were collected from the anterior and molar teeth of upper and lower jaws in the subjects, aged below 12 years old. A dental examination was performed for dft (decayed, filled, total) with the WHO caries diagnostic criteria. The mutans streptococci from the sample were cultured selectively on mitis salivarius-bacitracine (MSB) agar plate. For biotyping of mutans streptococci, biochemical test was performed. From the culture, bacterial genomic DNA was prepared for using of PCR template for the identification of mutans streptococci at the species-level. Forty strains of mutans streptococci were isolated from dental plagues of 40 patients. The biotype I (45%) and biotype IV (32.5%) were most frequently detected. The prevalence of S. mutans and S. sobrinus was 69% and 31%, respectively. There was no positive relationship between species and biotypes of mutans streptococci and dft index. Our results revealed that biotype I and S. mutans were frequently detected in Korean children and support that dental caries incidents by many causative factors not only bacterial factor.

Ozone tolerance of tree species was determined by standard index of physiological damages and biochemical defense responses under short-term ozone exposure. At the end of 150ppb $O_3$ fumigation, photosynthetic characteristics and antioxidative enzyme activities were analyzed in the leaves of five species(Koelreuteria paniculata, Firmiana simplex, Styrax japonica, Fraxinus rhynchophylla, Viburnum sargentii). Injury index was determined by the effect of ozone on photosynthetic parameters and malondialdehyde(MDA) content, and tolerance index was calculated using the rate of increase in superoxide dismutase(SOD), ascorbate-peroxidase(APX), glutathione reductase(GR) and catalase(CAT) activities. Apparent quantum yield(AQY), carboxylation efficiency(Ce) and photo-respiration rate(PR) decreased in the leaves of five species with increasing ozone exposure time. These parameters were considered as an appropriate indicator for stress evaluation. Antioxidative enzyme activities showed various results depending on the tree species, exposure time, and enzyme types. SOD activity of K. paniculata increased with ozone exposure time, and that of F. rhynchophylla increased only after 6 hours of ozone exposure. CAT activity of $O_3$-exposed F. simplex was lower than the control. Based on standard index, ozone tolerance ability of five species was determined as two tolerant species(F. rhynchophylla > K. paniculata) and three sensitive species(S. japonica > F. simplex > V. sargentii).
