This study was designed to find out the status of low sodium diet in 27 hospitals located in Seoul and rural areas. The study was conducted from the beginning of June, 1976 to October, 1976. The differences in Na, protein and calorie contents between the hospitals in Seoul an ones in rural areas, and between the medical college attached hospitals and general ones, were compared by means of t-test. Correlation coefficient were made among Na, protein and calorie. In order to find out which food group is the major source of Na in the diet, six food groups were divided and Na content in each was calculated. The results showed that average daily Na intake of 27 hospitals was 2,382mg which is regarded as mild restriction. Average daily protein and calorie intakes were 94gm and 2,438 cal respectively. About 60% of hospitals restricted sodium at mild level $(2,300mg{\sim}4,600mg)$ and 33% at moderate $(1,000mg{\sim}2,300mg)$ and only 7% of the subjects were Planning strict sodium restriction $(250mg{\sim}500mg)$ There was statistically significant differences in Na contents between Seoul and rural areas. But no significant difference was found between medical college attached hospitals and general ones. The correlation between the average daily intakes of Na and protein was found not to be significant but protein and calorie intakes were related each other. When the total sodium intakes divided into six groups, about 74% were supplied by condiments (Food group 6th).

Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

Oysters, especially are excellent source of several mineral including iron, zinc and selenium, which are often low in the mordern diet. They are also an excellent source of glycogen, vitamin B12 and considered the healthiest when eaten raw on the half shell in good tasted season from November to March. This study was investigated for the purpose of obtaining basic data which can be applied to processing of two kinds of canned boiled oyster (canned boiled oyster, canned boiled oyster in bamboo salt). Shucked oyster meat was cooked in steam (15min) after washing with water, filled 90g into can (301-3), added with salt solution and then precooked for 10 min. at $100^{\circ}C$. Canned boiled oyster was added 1.5% salt solution 60mL. Canned boiled oyster in bamboo salt was added 0.5% salt solution 30mL and 0.7% bamboo salt solution 30mL. The cans were seamed using a vacuum seamer, and then sterilized for various Fo values (Fo 8~12 min.) in a steam system retort at $116^{\circ}C$, $118^{\circ}C$. Viable bacterial count, proximate composition, pH, salinity, yield, VBN, amino-N, TBA, mineral, color value, free amino acid, hardness and sensory evaluation of two kinds of canned boiled oyster produced at various sterilization condition (Fo 8~12 min.) were measured after divide to meat and juice. The results showed that canned boiled oyster in bamboo salt sterilized at Fo 8 min. was the most desirable because this condition is the most economical and tasty.

A reduced NaCl intake for the general population of the world has been recommended to reduce the overall blood pressure level and hence to reduce the overall incidence of cardiovascular disease. A high NaCl diet convincingly contributes to elevated arterial pressure in humans and animal models of hypertension. Among individuals there is considerable variability of blood pressure responsiveness to NaCl intake. In normotensive as well as hypertensive subjects, blood pressure can be judged to be salt sensitivity (SS) when observed to vary directly and substantially with the net intake of NaCl. The prevalence of SS in normotensive adults in the U.S. ranges from 15% to 42% and in hypertensive adults from 28% to 74%. SS is a risk factor for hypertension and may be an important marker in the identification of children for hypertension prevention programs. High NaCl intakes produce expansion of the extracellular fluid volume and thus increase blood pressure. Nonchloride salts of sodium does not expand the extracellular fluid volume and does not alter blood pressure. Blood pressure response to NaCl may be modified by other components of the diet. Low dietary intakes of potassium or calcium augment NaCl-induced increases of blood pressure. Conversely, high dietary intakes of potassium or calcium attenuate NaCl-induced hypertension. A greater intakes of potassium or calcium may prevent or delay the occurrence of hypertension. SS occurs when dietary potassium is even marginally deficient but is dose-dependently suppressed when dietary potassium is increased within its normal range. Orally administered KHCO$_3$, abundant in fruits and vegetates, but not KCl has a calcium-retaining effect which may contributed to its reversal of pressor effect of dietary NaCl. Since nutrients other than NaCl also affect blood pressure levels, a reduced NaCl intake should be only one component of a nutritional strategy to lower blood pressure.

Gastric cancer has been consistently decreasing worldwide, whereas cardia gastric cancer is on the rise. This indicates that the exposure rates to epidemiological causes are changing. In this study, we aim to review the risk factors for gastric cancer with respect to cardia and non-cardia types. One of the most significant risk factors for gastric cancer is Helicobacter pylori infection. H. pylori infection is known as a risk factor for non-cardia gastric cancer, and there have been results indicating that H. pylori infection is not associated with cardia gastric cancer. However, in the East Asian region, there is epidemiological evidence suggesting that H. pylori infection might be a risk factor for cardia gastric cancer. Smoking and alcohol consumption are known risk factors for gastric cancer, regardless of anatomical location. Obesity is considered a factor in the development of cardia gastric cancer. However, further research is needed to understand the specific relationship with non-cardia gastric cancer. The consumption of high-salt and processed meat is more distinctly associated with noncardia gastric cancer than in cardia gastric cancer. In addition to these factors, exposure to chemicals and radiation are considered risk factors for gastric cancer. Primary prevention of gastric cancer involves eliminating or avoiding risk factors such as H. pylori eradication and adopting a healthy lifestyle, including quitting smoking, reducing alcohol consumption, maintaining a healthy weight, and having a low-salt diet.

장기적으로 소금 섭취량을 달리 한 정상 및 고혈압쥐에서 atrial natriurectic peptide (ANP) 가 혈압, renin-aldosterone 및 신배설에 미치는 효과를 비교하였다. 생후 6주된 spontaneously hyper-tensive rate (SHR)와 Wistar 숫쥐를 각각 저염, 정상염 및 고염 (2, 10, 25 mmol NaCl/100g diet) 군으로 나누어 실험 식이를 6주동안 먹었다. 실험 당일 아침에 쥐를 ether로 마취시킨 상태에서 대퇴 동맥과 정맥 및 방광에 catheter를 삽입한 다음에 쥐를 restraining cage에 넣어 고정시켰다. 마취가 깨고 혈압이 안정된 후에 정맥관으로 0.9% saline을 0.02ml/min의 속도로 80분간 주입하고 안정시 뇨와 혈액을 채취하였다. 그후 ANP를 380 ng/kg/min의 속도로 20분간 주입하였으며 그동안 10분 간격으로 요를 채취한 다음 채혈하였다. 혈장 aldosterone 농도와 renin 활성도 (PRA)를 방사면역법으로 측정하였다. ANP를 주입하기 전에 SHR 고염군의 평균동맥압은 정사염이나 저염군보다 유의하게 높았으나, Wistar의 혈압은 소금군 사이에서 차이가 없었다. ANP 주입전의 혈장 aldosterone 농도는 소금 섭취량이 많을수록 유의하게 낮았으며, Wistal 군이 SHR 보다 높은 값을 보였다. 혈장 renin 활성도는 소금군 간에 차이가 없었으며, Wistar와 SHR 간에도 차이가 없었다. 요량이나 Na, K 배설률은 소금군 간에 유의한 차이가 없었으나, SHR이 Wistar 보다 높은 경향을 보였다. Hematocrit 값도 소금군 간에 차이가 없었으나, SHR의 값이 Wistar 보다 유의하게 높았다. ANP를 주입하는 동안 혈압이 점진적으로 감소하여 20분후에는 $20{\sim}30\;mmHg$ 정도 감소하였으나, 각 소금군사이에 차이가 없었다. 그러나, ANP에 의한 혈압 강하 정도는 SHR이 Wistar 보다 유의하게 높았다. ANP 주입 후에는 모든 군에서 aldosterone과 혈장 renin 활성도가 유의하게 감소하였는데, aldosterone의 감소 정도는 저염군에서 가장 크게 나타났다. ANP의 이뇨 및 Na 배설 항진효과는 Wistar에서는 소금군 간에 차이가 없었으나, SHR 에서는 고염군의 Na 배설률이 저염군보다 유의하게 높았다. ANP의 혈압강하 효과나 Na 배설 항진효과가 SHR에서 Wistar 보다 유의하게 높게 나타났으나, 이뇨반응, renin 및 hematocrit의 변화에는 차이가 없었다. 이상의 결과에서, 장기적으로 소금 섭취량이 다름에 따라 ANP의 효과 중에서 특히 aldosterone 분비나 SHR의 Na 배설에 차이가 나타났는데 그 작용 기전은 확실치 않다.

Purpose: This study analyzed the general status and conditions of the kimchi industry in Korea. The purpose of this study is to contribute to the information of a desirable kimchi market by analyzing the distribution, price, market, and consumers of kimchi based on the current status and status of the kimchi industry in Korea. Research design, data and methodology: This study basically conducted research design and analysis based on theoretical consideration and kimchi market data. Results: The conclusion of the study is that in order to globalize kimchi, it is expected that a strategy to target overseas markets with relatively low competition through a low-salt diet and premium strategy along with the image of Western health is expected. Conclusions: In Korea, small and medium-sized companies can target the B2B (Business-to-Business) market first and then target department stores or convenience stores at a stable time in the future to expand sales channels and profitability through premium or low-cost policies. Another strategy is to target overseas markets as soon as the company stabilizes through B2B. Therefore, in the kimchi industry, it is necessary to establish a sales/marketing strategy according to what position and position of one's own company in the kimchi industry.

The effects of different mineral supplementations on the milk yield of free-ranging Somali camels were investigated in two phases in a semi-arid region of northern Kenya during the dry and wet seasons in 2002 and 2003. In phase 1, twelve (12) lactating camels were selected at random to form four (4) groups each consisting of three camels. The first group served as the control and as a result received no mineral supplementation. In addition to the control diet the other groups received oral doses of minerals as follows over a 60-day period: T1 (P), T2 (High Cu low Co) and T3 (Low Cu high Co). The daily milk yield and blood mineral profiles were measured during the wet and dry seasons. The mean daily milk yield increased from 3.4 L/d to $4.3{\pm}0.3L/d$ and 5.2 L/d in the dry and wet seasons, respectively. Fifteen (15) lactating camels were selected at random to form five groups each consisting of three replicates. The control group did not receive any mineral supplement. The other four groups in addition to the control diet, received the following treatments: T4 (Common Salt), T5 (High Co), T6 (High Co+P) and T7 (Low Co+P). Mineral supplement T6 produced significantly higher milk yield ($5.4{\pm}0.5$ and $6.5{\pm}0.7L/d$) during the dry and wet seasons. Both T6 and T7 had significantly higher milk yield than T4 and T5. During both phases, the blood Ca and P level significantly increased in camels receiving T1, 6 and 7. Animals that received only the trace mineral supplements had lower blood P compared to the ones receiving supplementary P and also the control. Supplementation of lactating camels with Co and P significantly (p<0.05) increased milk yield). Effect of common salt, commonly given by farmers, on milk yield was insignificant. It was concluded that mineral supplementation to lactating camels was beneficial, and that mineral supplements should include P and Co. Further research is required to establish P and Co requirements of lactating camels.

Hypertension is one of the most well known risk factors for cerebrovascular or coronary heart disease and is a major public health problem. Early detection and treatment of hypertension are essential, but the compliance of treatment on hypertension is not easy to achive. Hypertensive workers are being detected by the annual screening under the Labour Standard Law in Korea but the solidified control system for them is not existing. This study about workers 'Motive-Belief-Action in non-drug and drug treatment of their hypertension would be worthwhile to interpret how the workers actually behave in coping with hypertension, and also would be advisable to construct the follow-up program in Korea. In the field research process two criteria were used to select sample group. The first criterion included the workers who were screened to be hypertensive with their blood pressure above 160/95 in this survey. The second one was used to classify study-group respondents who had known their hypertension by successive annual screening. From such criteria a total of 156 male workers were sampled in 21 industries, the author interviewed them using the structured questionnaire which consisted of Belief-Motive-Action items about non-drug and drug treatment for hypertension with open-ended question on symptom of hypertension. The summary is as follows: 1) Sixty-one percent of respondents had ever checked their blood pressure somewhere besides the annual screening. 2) Most respondents(97.2%) complained no symptoms of hypertension at all. 3) Belief level of non-drug treatment was relatively high (82.1%-64.7%), but motive(55.1%-28.2%) and action(38.5%-16.7%) levels were low. 4) Belief level of drug treatment was relatively lower than that of non-drug treatment, blue collar workers showed higher artier level of drug treatment than white collar workers, and correlation coefficient between belief and motive on drug treatment was lower in group of not-recognizing their family history of hypertension than recognized group. Such findings indicated that belief on drug treatment of hypertensive workers would be problematic. 5) White collar workers showed significant lower correlation coefficients between Motive and Action of salt restriction, restriction of fatty diet and relaxation than blue collar workers. 6) Mild hypertension group showed low levels of Motive and Action of non-drug treatment(salt restriction, restriction of fatty diet and relaxation) and also showed low correlation coefficient between Belief and Motive of above non-drug treatment.

As the seriousness of hypertension in adults is increasingly recognized, attention is being focussed on its control through continuous health supervisions. Complications arising from high blood pressure exceed those of many other adult health problems and affect the nursing needs of these patients. In order to contribute to effective nursing care planning and improved health supervision, 248 medical records of hypertensive patients admitted to Internal Medicine at Ewha Medical Center from January 1971 to August 1976 were examined. Results were as fellows: 1. The sample group averaged 5.0% of the total number of patients admitted to internal medicine during the period studied. The proportion increased slightly with each successive year. 2. Patients with hypertension averaged 31.4% of all patients with cardiovascular discease. This proportion was stable over the period. 3. Hypertensive patients were primarily in their 40s. The average age was 55.1 years. 4. Women were most frequently affected in their 60s and men in their 40s. 5. The bloo pressure of these in their 30s was not well controlled on discharge. Rates for those in their 30s averaged 151.5/107mmhg, for those in their 40s 161.5/110mphg, and for those in their 60s 169/100mmhg. 6. Complications increased with each age range from the 40s to the 60s for both men and women. 7. Complications related to systolic hypertension occurred most frequently when the rate exceeded 200mmhg. Cerebral vascular accident was the primary complication, presenting implications for nursing intervention. 8. Complications related to diastolic hypertension occurred most frequently when the rate was in the $110{\sim}129mmhg$ range. C.V.A. again was the primary complication needing nursing care planning. 9. Diets ordered for patients were low salt 79.%, salt free 4.19%, diabetic 6.1%, and protein free ('no protein') 2.0%. Caloric, salt end protein levels were not defined. Recommendations based on the findings were directed to diet and other therapies.
