To survey the most feeding frequence of formulated diet as food for cultured puffer in winter season, we performed a rearing test using juveniles of river puffer, Takifugu obscurus (body weight 15.0 g) for 120 days. The feeding frequencies were set up as 2times/1day, 2times/2days, 2times/3days and 2times/4days. We tested triplicately the experiment and investigated survival rate, daily food intake (DFI), feed efficiency (FE), condition factor (CF), daily growth rate (DGR). Consequently, growth was increased following to an increasing of feeding frequency, was the fast in 2times/1day of feeding frequency, and was the slowest in 2times/4days (p<0.05). DFI and CF were increased following to an decreasing of feeding frequency and was the highest in 2times/4days of feeding frequency. FE was decreased following to an decreasing of feeding frequency, and was the highest in 2times/1day of feeding frequency. In a proximate carcass composition at the final day, moisture and crude lipid contents were the lowest in 2times/4days, and in survival, there was not any significant difference among experimental groups. Therefore, we concluded that the 2times/2days are the best of feeding frequency for economical benefit of river puffer culture in winter season.

In this paper, this writer looked into the initial law and fortification, which are two of the most important phonetic changes of Sino-Korean words. Pronunciation and inscription rules of Oriental Medical terminologies have also been studied. Moreover, several problems of meaningful rendering of Oriental Medical Chinese terminologies into Korean have been looked into. As a result, the following conclusions could be drawn. 1. The initial law only applies to Sino-Korean words that consist of more than one syllable. It does not apply to words borrowed from foreign languages. Especially, compound words like Jang-ssi-yu-gyeong(張氏類經) or Im-sin-yuk-hyeol(姙娠衄血) consist of already existing words such as Jang-ssi(張氏), Yu-gyeong(類經), Im-sin(姙娠), and Yuk-hyeol(衄血), and thus the initial law applies to these words. They are inscribed and pronounced 'Jang-ssi-yu-gyeong' and 'Im-sin-yuk-hyeol'. 2. Fortification of Sino-Korean words can be applied variously according to the structure and meaning of the words. Words such as '科', '格', '氣', '法', '病', '症', and '證' are often fortified and at the same time used frequently in Oriental Medicine. Also, many other words are derived from these words. However, there has not been a scholastic consent among the Oriental Medical society as to in which circumstances these words will be fortified. Therefore, a standardization process to stipulate the pronunciation of Oriental Medical terminologies is necessary. 3. Meaningful rendering of Oriental Medical Chinese terminologies into Korean also needs scholastic investigation. Especially, the word 兪 should be meaningfully rendered and pronounced 'su' just like the words 輸 and 腧, but is wrongly pronounced 'yu'. Other than this, the words 井滎兪經合, 秦艽, 膻中, 共振丹, 成無已, and 麗澤通氣湯 should respectively be pronounced 'jeong-hyeong-su-gyeong-hap', 'jin-gyo', 'dan-jung', 'gong-sin-dan', 'Seong-mu-yi', and 'Yi-taek-tong-gi-tang'. Moreover, there are four pronunciations to the word 梴 of 李梴. This should also be standardized. This writer proposes that in the future, correct meaningful rendering of Chinese terminologies into Korean and phonetic signs be inscribed in dictionaries regarding Oriental Medical terminologies.

Two consecutive feeding trials investigated the effects of feeding rate and pellet expansion by water-soaking on the growth performance, blood components and histology of olive flounder Paralichthys olivaceus. The first two experiments were carried out to determine the effects of pellet expansion and feeding rate. In the first experiment, growth performance, feed utilization and survival of fish were not significantly affected by pellet expansion for six weeks. There were no significant differences in hematocrit, hemoglobin, aspartate aminotransferase, alanine aminotransferase, glucose and total protein of fish fed the expanded pellet. However, whole-body lipid content of fish in the non-expanded group was significantly higher than that in the expanded group. Histological analysis of the anterior intestine revealed that fish in the expanded group had shorter and smaller mucous folds. These results indicate that pellet expansion had no beneficial effect in terms of growth performance, feed utilization and fish health. In the second experiment, weight gain and feed efficiency were significantly increased as feeding rate increased from 0 to 2.5% body weight per day (BW/d), but there were no significant differences in weight gain or feeding efficiency in fish fed the expanded pellet at ratios of 2.5% BW/d and satiation for three weeks. Plasma aspartate aminotransferase activity of fish fed the expanded pellet at a ratio of 2.5% was significantly lower than that of starved fish. Histological analysis of the anterior intestine revealed that fish in the 0% group had shorter mucous folds. Broken-line regression analysis suggested that the optimum juvenile olive flounder feeding rate was 3.5% BW/d during the low temperature season ($16-17^{\circ}C$).

A feeding trial was carried out to investigate the effect of different fish meal and wheat flour contents in extruded pellets on the growth and apparent nutrient digestibility of olive flounder Paralichthys olivaceus. Four extruded pellets (HB1, HB1T, HB2 and HB2T) were prepared using two kinds of high quality brown fish meal and low quality tuna fish meal. Two diets (HB1 and HB2) contained two different kinds of brown fish meal, respectively; in HB1T and HB2T, we substituted 50 % of the brown fish meal with 10 % wheat flour. Three replicate groups of fish (initial body weight of 82 g) were fed the experimental pellets to visual satiation for 15 weeks. The highest weight gain was observed in fish fed HB1, and weight gain of fish fed HB2 was significantly higher than that of fish fed HB2T (P<0.05). Feeding efficiency for fish fed HB1 was significantly higher than that of fish fed HB1T and HB2T (P<0.05), but was not significantly different from fish fed HB2. Apparent dry matter digestibility in HB1 and HB2 was significantly higher than in HB1T and HB2T (P<0.05). The highest crude protein digestibility was observed in HB1, and protein digestibility in HB1T and HB2 was higher than in HB2T (P<0.05). The results of this study suggest that fish meal quality considerably affects growth and nutrient digestibility of olive flounder fed extruded pellets, and the use of HB1 is recommended over HB1T, HB2 and HB2T for efficient olive flounder production.

Everyone once in a life experience headaches as symptoms are very common. According to a study in a country of more than a week and as many as those who have experienced a headache amounts to 69.4%. In addition, the high reported prevalence of migraine in 30s for 80% of all migraine sufferers daily life interfere with work or was affected. In Western medicine, the cause of headaches is traction or deformation of pain induced tissue like scalp, subcutaneous tissue, muscle, fascia, extracranial arteriovenous, nerves, periosteum. But it turns out there are not cause why pain induced tissue is being tracted or deformated. Therefore, most of the western-therapy is mainly conducted with regimen for a temporary symptom reduction. Therefore, I examined how it has been developed in Chinese Ming Dynasty, the perception of headache, change in disease stage and an etiological cause. Oriental medicine in the treatment of headache is a more fundamental way to have an excellent treatment. The recognition of head in "素問($s{\grave{u}}$ $w{\grave{e}}n$)" and "靈樞($l{\acute{i}}ng$ $sh{\bar{u}}$)" began to appear in 'Soul-神($sh{\acute{e}}n$) dwelling place' and 'where to gather all the Yang-'諸陽之會($zh{\bar{u}}$ $y{\acute{a}}ng$ $zh{\bar{i}}$ $hu{\grave{i}}$)'. Also, head was recognized as '六腑($li{\grave{u}}f{\check{u}}$) 淸陽之氣($q{\bar{i}}ng$ $y{\acute{a}}ng$ $zh{\bar{i}}$ $q{\grave{i}}$) and 五臟($w{\check{u}}$ $z{\grave{a}}ng$) 精血($j{\bar{i}}ng$ $xu{\grave{e}}$) gathering place'. More specific structures such as the brain is considered a sea of marrow(髓海-$su{\check{i}}$ $h{\check{a}}i$) in "內經($n{\grave{e}}i$ $j{\bar{i}}ng$)" and came to recognized place where a stroke occurs. Accompanying development of the recognition about head, there had been changed about the perception of headache and the recognition of the cause and mechanism of headache. And the recognition of headache began to be completed in Ming Dynasty through Jin, Yuan Dynasty. Chinese Ming Dynasty, specially 樓英($l{\acute{o}}u$ $y{\bar{i}}ng$), in "醫學綱目($y{\bar{i}}xu{\acute{e}}$ $g{\bar{a}}ngm{\grave{u}}$)", first enumerated prescription in detail by separating postpartum headache. and proposed treatment of headache especially due to postpartum sepsis(敗血-$b{\grave{a}}i$ $xu{\grave{e}}$). 許浚($x{\check{u}}$ $j{\grave{u}}n$) accepted a variety of views without impartial opinion in explaining one kind of headache in "東醫寶鑑($d{\bar{o}}ng-y{\bar{i}}$ $b{\check{a}}oji{\grave{a}}n)$" 張景岳($zh{\bar{a}}ng$ $j{\check{i}}ng$ $yu{\grave{e}}$), in "景岳全書($j{\check{i}}ng$ $yu{\grave{e}}$ $qu{\acute{a}}nsh{\bar{u}}$)", established his own unique classification system-新舊表裏($x{\bar{i}}nji{\grave{u}}$ $bi{\check{a}}ol{\check{i}}$)-, and offered a clear way even in treatment. Acupuncture treatment of headache in the choice of meridian has been developed as a single acupuncture point. Using the classification of headache to come for future generation as a way of locating acupoints were developed. Chinese Ming Dynasty, there are special treatments like 導引按蹻法($d{\check{a}}o$ y ${\check{i}}n$ ${\grave{a}}n$ $ji{\check{a}}o$ $f{\check{a}}$), 搐鼻法($ch{\grave{u}}$ $b{\acute{i}}$ $f{\check{a}})$, 吐法($t{\check{u}}$ $f{\check{a}}$), 外貼法($w{\grave{a}}i$ $ti{\bar{e}}$ $f{\check{a}}$), 熨法($y{\grave{u}}n$ $f{\check{a}}$), 點眼法($di{\check{a}}n$ $y{\check{a}}n$ $f{\check{a}}$), 熏蒸法($x{\bar{u}}nzh{\bar{e}}ng$ $f{\check{a}}$), 香氣療法($xi{\bar{a}}ngq{\grave{i}}$ $li{\acute{a}}of{\check{a}}$). Most of this therapy in the treatment of headache, it is not used here, but if you use a good fit for today's environment can make a difference.
