Objectives: To examine the effect of long-term Korean medicine treatment on mild cognitive impairment (MCI). Methods: This study was conducted on two patients who were diagnosed with mild cognitive impairment and received long-term Korean medicine treatment. In order to evaluate the degree of cognitive decline, SNSB and K-MMSE were performed 2~3 times at the first visit and during the treatment process. Results: Both cases 1 and 2 were diagnosed with MCI with a high possibility of developing dementia. In case 1, MCI progressed to early dementia at one year after the diagnosis of MCI. However, in case 2, that MCI status was maintained without progressing to dementia for 4 years after the diagnosis of MCI. The cause of such difference in the course of MCI might be attributed to the fact that Case 1 had lower K-IADL level but higher SGDS level than Case 2 at the time of initial diagnosis, with weak family support and irregular herbal medicine intake. Conclusions: Korean medicine treatment could improve and manage symptoms of cognitive decline due to MCI.

The purpose of this study was to investigate the effects of syrup medication for asthmatic children on the salivary invertase activity and caries experience. 26 ashmatic children for the study group and 30 healthy children for the control group were selected, respectively. Caries experience was examined and salivary reductase activity was tested. The parents of asthmatic children were asked to fill in the questionaire about syrup intake period and home dental behavior, and the parents of healthy children were asked to fill in the same questionaire without syrup intake period. The results were as follows : 1. The ds index of asthmatic children were higher than that of healthy children(P < 0.05). 2. There was significant difference in dt index between the intake period of 'shorter than 10 months' and 'longer than 20 months'. The ds, dft and dfs indices had a tendency to increase as the intake period increased. 3. The salivary reductase activity had a tendency to increase as the intake period of syrup increased.

We have found many beneficial effects of the long-tenn intake of Korean red ginseng (KRG) in human immunodeficiency virus (HIV) type-I infected patients, including the maintenance of CD4+ T cell count for 10 years with KRG only and the delayed development of resistance mutation to ZDV. In this study, to investigate whether KRG-intake could affect the clinical progression and nef gene variation, we determined 200nef sequences from 70 patients. Follow-up period was $8.8{\pm}2.9$ years and annual decrease in CD4+T cell was $41{\pm}57/ul.$ Nested polymerase chain reaction (PCR) and direct sequencing were perfonned with peripheral blood mononuclear cells (PBMC) obtained at times during the study period. First, there was a significant correlation between survival duration and duration of KRG-intake $(36.8{\pm}38$ months)(P=0.000). There were significant correlations between the last NefProg score and CD4+ T cell count (r= 0.208, P<0.05) and annual decrease in CD4+ T cell count (r =0.346, P<0.01) in 70 patients. In addition, there were significant correlations between KRG-intake and annual decrease (r= 0.323, P<0.01), and the CD4+ T cell count itself (r=0.229, p<0.05). Furthennore, there was also a mild significance between the NefProg score and the duration of KRG-intake in only SP and RP (n=30, r=-0.281, P=0.067). In addition, we detected various defects in 21 patients $(30.0\%),$ not including 5 premature stop codons. Ten $(12.5\%)$ patients showed repeated deletion of an amino acid. Four of 10 patients were gross deletions and they were treated with KRG for more than 20 months. The number of patients with repeated gross deletions was significantly higher in the order of slow progressors $(18\%)$, typical progressors($3\%$), and rapid progressors($0\%$) (P<0.05). We also observed that long-tenn intake of KRG might make the change from A or D to T at position 54 and decrease NefProg score. Taken together, our results show clear evidence that the long-term intake of KRG has effects on nef gene variation as well as definite clinical usefulness.

The development of a basin-wide runoff analysis model is to analysis monthly and daily hydrologic runoff components including surface runoff, subsurface runoff, return flow, etc. at key operation station in the targeted basin. h short-term water demand forecasting technology will be developed fatting into account the patterns of municipal, industrial and agricultural water uses. For the development and utilization of runoff analysis model, relevant basin information including historical precipitation and river water stage data, geophysical basin characteristics, and water intake and consumptions needs to be collected and stored into the hydrologic database of Integrated Real-time Water Information System. The well-known SSARR model was selected for the basis of continuous daily runoff model for forecasting short and long-term natural flows.

Objectives: Studies that reported the association between diet quality/nutritional intake status and mortality have rarely used long-term follow-up data in Asian countries, including Korea. This study investigated the association between the risk of mortality (all-cause and cause-specific) and the diet quality/nutritional intake status using follow-up 12-year mortality data from a nationally representative sample of South Koreans. Methods: 8,941 individuals who participated in 1998 and 2001 Korea Health and Nutrition Examination Surveys were linked to mortality data from death certificates. Of those individuals, 1,083 (12.1%) had died as of December, 2012. Cox proportional hazard models were used to estimate the relative risks of mortality according to the level of diet quality and intakes of major nutrients. Indicators for diet quality index and nutritional intake status were assessed using MAR (mean adequacy ratio) and energy and protein intake level compared with the 2010 Korean DRI. Results: Higher diet quality/nutritional intake status were associated with lower mortality; the mortality risk (95% confidence interval) from all-cause of lowest MAR group vs highest was 1.66 (1.27 to 2.18) among ${\geq}30$ year old, and 1.98 (1.36 to 2.86) among 30~64 year old individuals. Those with below 75% of energy and protein intake of Korean DRI had higher mortality risks of all-cause mortality compared to the reference group. Diet quality/nutritional intake status was inversely associated with mortality from cardiovascular diseases and cancer. Conclusions: Poor Diet quality/nutritional intake status were associated with a higher risk of mortality from all-cause and mortality from cardiovascular diseases and cancer among South Korean adults.

In this study, the effect of squid liver powder intake on accumulation of cadmium in mice was investigated. Subjects were divided into 4 groups including the control group (CON), squid liver powder group with lipids not removed (SLP100), and squid liver powder groups with lipids removed (LFSLP50 and LFSLP100). Feed intake and food efficiency ratio of squid liver powder groups was significantly higher than the CON. As a result of investigating cadmium content in hair, serum, liver, and kidney during intake of squid liver powder, all groups showed increase in cadmium accumulation through consistent, long-term intake. Especially, cadmium content in liver and kidney of LFSLP100 was significantly higher than the content of SLP100 and CON. As a result of pathological observation on liver and kidney tissues according to squid liver powder diet, LFSLP100 showed most serious pathological symptoms. In case of kidney tissues, degeneration was significantly more severe in LFSLP100 compared to other groups. Such results suggest that cadmium concentration in human body can be increased by ingestion of whole squid including internal organs and that tissues can be damaged by increased cadmium concentration. More specific and systematic studies are deemed necessary.

This study examined salty taste acuity and salty taste preference and sodium intake in relation to zinc nutritional status in 2 rural populations in Korea. And we also examined the main food contributors of their sodium intakes. We enrolled 218 adults (66 men and 152 women) from the Kangneung and Samcheok regions in Korea's Kangwon province in our study conducted from December 2011 to February 2012. Participants from each region were divided into 3 groups based on their serum zinc level (T1: lowest, T2: intermediate, T3: highest). We compared the salty taste acuity and preference, Na index (Dish Frequency Questionnaire for estimation of habitual sodium intake), blood pressure, and intakes of nutrients including sodium by 3 groups of serum zinc level. The results were as follows: a higher serum zinc level indicated a lower sodium intake and Na index (P<0.05). The salty taste acuity was considerably higher for participants from the Kangneung region than those from the Samcheok region (P<0.05). And the serum zinc level was significantly higher in participants from the Kangneung region than those from the Samcheok region (P<0.05). We further divided the participants into 2 groups: those who consumed more zinc than the recommended intake (RI) and the others. We compared salty taste acuity and salty taste preference in the 2 groups. The salty taste threshold and palatable salty taste concentrations were lower for the group with a zinc intake above RI than for the group with zinc intake below the RI. However, the difference was not significant. This study confirms that taste function differs depending on zinc nutritional status. In future, it is required to a large-scale, long-term, prospective study on the correlation between zinc intake, serum zinc levels, and taste perception function and blood pressure.
