$Bi_{0.5+x}(Na_{0.78}K_{0.22})_{0.5-3x}TiO_3$ ceramics with an excess $Bi^{3+}$ and a deficiency of $Na^+$ and $K^+$ were synthesized by a conventional solid state reaction method. The structure and morphology of $Bi_{0.5+x}(Na_{0.78}K_{0.22})_{0.5-3x}TiO_3$ ceramics were characterized by X-ray diffraction and field emission scanning electron microscopy. The electric polarization and mechanical strain induced by external electric field, and the temperature dependence of dielectric constant were investigated. These results demonstrated that an ergodic relaxor phase can be induced by controls of the mole ratio of $Bi^{3+}$, $Na^+$ and $K^+$. A phase boundary between non-ergodic and ergodic relaxor phases can be observed at ambient temperature. The ergodic relaxor phase can be transferred to the ferroelectric phase by application of the electric field. The stability of the induced ferroelectric phases strongly depends on the mole ratio of $Bi^{3+}$, $Na^+$ and $K^+$. The maximum strain of 0.31% was observed in $Bi_{0.51}(Na_{0.78}K_{0.22})_{0.47}TiO_3$ ceramics sintered at $1,150^{\circ}C$ for 2 h.

Zinc is one of the essential trace elements in the living organism for growth and health. The first identified metalloenzyme, carbonic anhydrase, is a zinc compound and several others have been described since. Among zinc deficiency syndromes in animals porcine parakeratosis has been successfully treated with zinc supplements, and in man a syndrome of anemia, hypogonadism, hepatosplenomegaly, and dwarfism, prevalent in parts of Iran and Egypt, has been ascribed to lack of zinc in the diet. Dietary zinc excess in the rat is manifested by a hypochromic, microcytic anemia, poor growth, reduction in liver catalase and cytochrome oxidase. The present study is an attempt to delineate the changes of tissue contents of trace elements, especially of iron, copper and zinc in liver and kidneys of the rats. Weanling albino rats, weighing 60 to 80gm. were used in this experiments. The rats were housed in cages with aluminum floors and received feed and distilled water ad libitum. Animals were divided into three groups, control, low zinc diet and high zinc diet groups. The high zinc diet group was subdivided into 0.5% Zn and 0.7%Zn groups. The supplementary copper or iron was added to the high dietary zinc groups. The animals were sacrificed and the tissues were washed several times with deionized water. The wet digested samples were analyzed by Hitachi Model 207 atomic absorption spectro-photometer for the determination of iron, copper and zinc in the liver and kidney. Hemoglobin level in the blood was measured by cyanmethemoglobin method. The results of this study are as follows: 1) All rats fed high zinc diets and low zinc diets gained less weight than control. Weight gain was not improved by the supplementary copper or iron and both. 2) Hemoglobin concentration was decreased significantly in the rats fed high zinc diets and less in the low zinc diet. Supplementary copper and iron to the higher zinc diet appeared to give some improvement of anemia. 3) The iron contents of the liver and kidneys were significantly decreased in the high zinc groups and the reduction was more significantly in the rats receiving higher zinc diet (0.7%). The supplementary copper caused a further depression of liver iron. On the other hand, the iron, added to the high zinc diet lessoned the severity of the decrease in liver iron and caused kidney iron to be maintained almost at the level found in the rats fed by zinc and supplementary copper diet. 4) High zinc diets did not change copper content of the liver and kidney. Supplementary copper elevated the concentration in the liver and kidney and added iron had no effect on the accumulation of copper in the liver and kidneys. 5) The high zinc diets caused marked increases of zinc content in the liver and kidney. Supplementary iron to the high zinc diet caused increases of zinc contents of liver and kidneys.

Objectives: This study analyzed the clinical characteristics of patients with functional dyspepsia (FD) who received Korean medicine treatment. Methods: A retrospective chart review was conducted to investigate sociodemographic characteristics, clinical characteristics, and prescribed treatments. The clinical records of 192 patients who visited Kyung Hee University Korean Medicine Hospital for FD from May 1, 2022, to May 31, 2023, were analyzed. In addition, the distribution of pattern identification and symptom type according to body mass index (BMI), as well as prescription history, were analyzed. Results: As the degree of obesity increased, the proportion of Spleen-Qi deficiency pattern patients decreased (p=0.012), and the proportion of damp-phlegm pattern patients increased (p=0.000). Additionally, as the degree of obesity increased, the proportion of patients with excess differentiation increased (p=0.002). The PDS (Postprandial distress syndrome) symptom type was significantly more frequent in the underweight and normal groups than in the overweight and obese groups, and the EPS (Epigastric pain syndrome) symptom type was more frequent in the overweight and obese groups. Regardless of the type of pattern identification, the most frequently used prescriptions were Naesowhajung-tang, Hanshin Naeso-san, and Sojeokgunbi-hwan granule. Conclusion: This study analyzed the medical records of patients with FD to elucidate the use of Korean medicine treatments. Our study is meaningful in that we found that the distribution of pattern identification and symptom patterns are linked to the degree of obesity in FD patients and identified the tendency for herbal medicine treatments to be prescribed in clinical practice.

Background: Allergic rhinitis(AR) is a heterogeneous disorder that despite its high prevalence is often undiagnosed. It is characterized by one or more symptoms including sneezing, itching, nasal congestion, and rhinorrhea. And it is frequently accompanied by symptoms involving the eyes, ears, and throat, including postnasal drainage. There are many different causes of rhinitis in children and adults. Approximately 50$\%$ of all cases of rhinitis are caused by allergy. In the case of rhinitis caused by allergens, symptoms arise as a result of inflammation induced by a gamma globulin E-mediated immune response to specific allergens such as pollens, molds, animal dander, and dust mites. The immune response involves the release of inflammatory mediators and the activation and recruitment of cells to the nasal mucosa. AR is similar to 鼻？, hypersensitive rhinitis in Oriental Medicine. I think hypersensitive rhinitis is including of AR, vasomotor rhinitis and non-allergic rhinitis related with eosinophil increased and so on. Purpose: To perform a clinical analysis of hypersensitive rhinitis including allergic rhinitis and estimate the efficacy of Oriental Medical treatment. Objective: We studied 96 patients who had visited our hospital with complaints of nasal symptoms from March 2000 to February 2002; they had the signs more than 2 - nasal obstruction, watery discharge, sneezing and eye or nasal itching. Parameters Observed & Methods: We treated them with acupuncture & herb-medication. Sometime they used aroma oil or external medicine. 1) the distribution of sex & age groups 2) the clinical type based on duration & the severity of symptom 3) the breakdown of complication & pasl history of Otolaryngologic or allergic disease 4) the clinical assessment and classification of rhinitis(sneezers and runners & blockers) 5) the associated symptoms and signs 6) the classification of Byeonjeung 7) the classification of prescriptions and 8) the efficacy of treatment. Result: 1. In the clinical type of based on duration, the intermittent type was 42.7$\%$ and the persistent was 57.3$\%$. 2. We observed the severity of symptoms based on the quality of life. The mild type was 24.0$\%$ and the moderate-severe was 76.0$\%$. 3. In the clinical assessment and classification of rhinitis, the sneezers and runners type was 69.8$\%$ and the blockers was 30.2$\%$. 4. The most common family history with otolaryngologic or allergic disease were allergic rhinitis(17.7$\%$), urticaria, paranasal sinusitis and T.B.(3.1$\%$). 5. The most common past history with otolaryngologic or allergic disease were paranasal sinusitis(14.6$\%$), atopic dermatitis and asthma(8.3$\%$). It was 31.3$\%$ they had a family history and 44.8$\%$, past history. 6. The most common complication was paranasal sinusitis(15.6$\%$). In decreasing order the others were otitis media with effusion(9.4$\%$), GERD and headache(6.3$\%$), asthma, bronchitis, nasal bleeding and allergic dermatitis(5.2$\%$). 7. Classification through Byeonjeung : ⅰ) 39 cases(34.9$\%$) were classified as showing Deficiency syndrome. The insuffficiency of Qi was 17.7$\%$, deficiency of Kidney-Yang, 12.5$\%$ and Lung-Cold, 10.4$\%$. ⅱ) 57 cases(59.4$\%$) were classified as showing Excess syndrome. The Fever of YangMing-meridian was 35.4$\%$, Lung-Fever, 24.0$\%$. 8. The efficacy of treatments showed: an improvement in 22cases(22.9$\%$); an improvement partly in 24 cases(25.0$\%$); no real improvement or changes in 16 cases(16.7$\%$); and couldn't check the results 18cases(18.6$\%$). Conclusion: We suggest that this study could be utilized as a standard of clinical Oriental Medical treatment when we treat hypersensitive rhinitis including allergic rhinitis.

This study is on the etiological factors of the obesity, symptoms of a disease caused by the etiological factors and the method of medical treatment resulted from symptoms of a disease, it is based on Dong-Yi Bo Gam. The conclusion of this study is as follows. 1. The final metabolic of fat is depend on the defensive energy. The shape of fatty layer is changed by the point where the defensive energy is replenish or not. So 'Goin(暠人)' 'Bein(肥人)' and 'Yuckin(肉人)' is made a discriminated and there is defferent between 'Besudaeso(肥瘦大小)' and 'Herlqidaso(血氣多少)'. 2. Etiological factors of obesity is ; essential substance from cereals overcome the primodial energy, spleen and stomach are strong at once, spleen and stomach are weak at once, spleen is disturbed by evil energy, retention of phlegm and fluid, muscle is weak, blood is excess but energy (qi)is weak, hua-sid(華食) eating the sweat food very often, a rich fatty diet. 3. To investigate each syndrome as etiological factons, essential substance from cereals overcome primodial energy is divided into two case: one is the food increase itself because of the weakness of stomach energy (qi), the other is not to digest the food because liver overact spleen by seven emotion. The obesity because of strengthen of the spleen and stomach at once do not feel hungry very well and spleen and stomach do not damaged easily by overacting. The obesity because of weakness of spleen and stomach at once, and disturbace in spleen cause by evil energy, gain the weight even if they eat food a little. Also it is hard to move four limbs. Weakness of muscle is weakness of spleen and stomach. Weakness of muscle is caused by weakness of spleen and stomach. That is the case of faining the weight because of eating food with an empty stomach. The obsity caused by retention of fluid has intestine rumbling and gain the weight suddenly. 4. The method of medical treatment fallowing to the etiological factors: The food is inclined to increase itself caused by weakness of stomach energy, In case of the obseity caused by this phenomenon. We can use Decoction for Reinforcing Middle wanner and Replenishing Qi(補中益氣湯), five tastes il-going-san(左味異功散) and so on. The method of medical treatment on obsity caused by strengthen of spleen and stomach is not referred yet. But we must investigate about using peptic powder(平胃散), ji-chul-huan(枳朮丸) for strengthen of stomach qi (胃氣). If the obesity appear caused by weakness of spleen and stomach and disturbance in spleen as to evil energy, and in the same time stomach qi is weak, we can use li-gong san(異功散). If not only obesity but also indigestion, we can use Decoction for naurishing the stomach and promotion eating(養胃進食湯). If not only obesity but also weakness of spleen and stomach, we can use Decoction for Reinforcing Middle warmer and replenishing Qi(補中益氣湯). The energy being weak, we can use Decoction for six noble drugs(六君子湯). If the obesity appear because of retention of fluid, we can use sin-chul-huan(神朮丸). On the obesit, caused by excess of blood and weakness of qi(血管氣虛), there is not method of mectical treatment yet, but the method of medical treatment that we count of first important maybe to invigorate the spleen and the lung qi and to disperse and recitify the depressed liver energy(疏肝利氣). The method of medical treament about the obesity caused by a rich fatty diet is not mentioned yet, but it is important to improve the lifestyle of food and we think that invigorate the spleen, and the lung-qi(補疏肝氣) and disperse and recitify the depressed liver-energy (??肝利機) amy count of first important. 5.There is useful medicine for weight down for example Herb tea(茶), red bean, wax gourd, etc. 6.The etiological factors of the obesity that revive frequently is weakness of qi(氣虛), from 形成氣衰, deficiency of yang, hasty of qi, damp and so on. The symptoms and sign of a disease that revive frequently to the obesity is appoplexia(中風), leucorrhea, reddish and whitish turbid, feeling of fullness in the upper abdomen, diabetes and so on.

본 연구는 대마난류의 주류역인 동해 남부해역의 포항 연안의 6개 정점에서 1994년 4월 26일부터 29일까지 수층별로 채수하고, 이 해역에서 $^{210}Po$와 $^{234}Th$의 제거속도 혹은 체류시간과 제거과정을 알아보았다. $^{210}Po$는 대체적으로 연안쪽 정점들에서는 표면혼합층에서 낮고 수온약층을 포함한 하부층에서 다소 높지만, 바깥쪽 정점들에서는 표면혼합층에서 오히려 높아지는 경향을 보였다. 그러나 $^{210}Pb$는 수심이 깊어짐에 따라 점차 감소하는 경향을 보였다. 또한, 표면 혼합층에서는 대체적으로 $^{210}Po$가 어미핵종보다 부족량을 보이나, 수온약층을 포함한 하부층에서는 어미핵종과 거의 방사평형된 농도를 보이거나 약간의 과잉량을 보였다. $^{210}Pb$는 표면혼합층에서는 어미핵종인 $^{226}Ra$보다 과잉량을 보이나, 수온약층을 포함한 하부층에서는 약간 부족량을 보이거나 혹은 거의 방사평형된 농도를 보인다. $^{234}Th$는 표면혼합층과 수온약층이 그 하부층보다 현저히 낮다. $^{210}Po$의 체류시간은 $1\~4$년의 범위로 비교적 연안쪽의 정점들 (E3, E4, E5)이 바깥쪽에 위치한 정점들(E6, E7)보다 짧았다. 그러나 정점 E8에서는 약 10년으로 매우 길었으며, 이는 다른 정점들에 비해 표면혼합층이 두꺼운 관계로 하부 표면혼합층에서 재순환된 $^{210}Po$가 수직혼합되었기 때문일 것이다. 한편, $^{234}Th$의 체류시간은 $52\~74$일의 범위로 정점별 차이가 그다지 크지 않았으며, $^{210}Po$의 체류시간에 비해서 훨씬 짧았다. 표면혼합층 내에서 해수중 $^{234}Th$는 용존태의 수층별 제거속도상수가 총부유물질과 정의 상관성을 나타내는 것으로 보아 주로 비생물기원의 무기입자에 흡착되어 제거되고 있는 반면에, $^{210}Po$는 용존태의 제거 속도상수가 클로로필 $^{210}Po$와 정의 상관성을 나타내는 것으로 보아 주로 생물체 (주로 동${\cdot}$식물플랑크톤)에 흡수되어 제거되고 입자물질 농도에는 크게 영향을 받지 않는 것 같다.
