The objective of this study is to research the costume of Three Han to be recorded in -$\ulcorner$Samkukgy$\urcorner$ Tongyjeon. They were written tattoos, broad head, physique, hair style, dress. accessories-lnsu, beads, head dress, shoes and cloths in Tongy-jeon. The results of this study are as fellows: Tattoos were common in Three Han. Those may be carved by chinese ink on body except a face. Broad head was Byonhan and Jinhan s customs. The physique of Mahan and Byonhan s men was tall and big. The hair style was just topknot not to put on a hat in Mahan, long hair In Byonhan and short hair for slaves in Jinhan. And then tattoos, flat head and skull, long hair style were the southern style. The dresses were two piece style-po and trousers. The shoes were made of leather. Those were the northern style. Eui-Chek, In-Su were royal gift of china. And they put valuable on beads, not gold, silver and golden embroidery cloths. This was different from other countries, And so we can find the variety of cultures at that time. The varieties came from the southern, northern, china and unique style.

Objectives. Spiral ganglion neurons (SGNs) include potential endogenous progenitor populations for the regeneration of the peripheral auditory system. However, whether these populations are present in adult mice is largely unknown. We examined the presence and characteristics of SGN-neural stem cells (NSCs) in mice as a function of age. Methods. The expression of Nestin and Ki67 was examined in sequentially dissected cochlear modiolar tissues from mice of different ages (from postnatal day to 24 weeks) and the sphere-forming populations from the SGNs were isolated and differentiated into different cell types. Results. There were significant decreases in Nestin and Ki67 double-positive mitotic progenitor cells in vivo with increasing mouse age. The SGNs formed spheres exhibiting self-renewing activity and multipotent capacity, which were seen in NSCs and were capable of differentiating into neuron and glial cell types. The SGN spheres derived from mice at an early age (postnatal day or 2 weeks) contained more mitotic stem cells than those from mice at a late age. Conclusion. Our findings showed the presence of self-renewing and proliferative subtypes of SGN-NSCs which might serve as a promising source for the regeneration of auditory neurons even in adult mice.

The one-dimensional ZnO nanostructures prepared through thermal evaporation under various cooling down procedures by changing the flow rates of the carrier gas and the reactive gas were investigated. The nanorod structures were changed into the nanonail types with a broad head through the reduction of the flow rate of the carrier gas. The decrease of the reactive gas reduced the length of the nail heads due to the limited mass transport of reactive gas. The intensity ratio of the ultraviolet emission/green emission of photoluminescence was proportional to the length of the broad head showing a larger surface area. The vertically aligned nanostructures were grown along the [0001] direction of ZnO regardless of the aligned directions. The crystal direction of the nanostructures was determined by that of the initial ZnO crystal.

Fibromatosis is a broad group of benign fibroblastic proliferation that shows locally aggressive growth but never metastasize. Common anatomic sites include abdominal wall, extremity, and mesentery. Little is reported about clinical features and outcome of fibromatosis of the head and neck. The treatment of choice is wide excision, which is often difficult. Postoperative recurrence rates are high. We recently confirmed a unique case of fibromatosis occurred on the hypopharynx of 44-year-old male patient and report this interesting case with review of literature.

In this paper, a design method of matching layers is presented for the sandwich type broad band underwater acoustic vibrators. The characteristic impedances of matching layers are determined to be matched to the characteristic impedance of head mass material. For the dynamic characteristic analysis of the sandwich type transducers, one dimensional FEM technique is also introduced. A test vibrator with the quarter wave matching layers has been designed to verify the proposed method. And the wide band characteristics of the input impedance and transmitting voltage response (TVR) are investigated.

The impact hammer is extensively used in experimental modal analysis as a means to provide force over a broad range of frequencies. The hammer mass and the impact head are often changed to achieve a desired impact time duration with its corresponding input frequency spectrum, these mass changes affect the performance and sensitivity of the force transducer employed to measure the impact force. Both a mathematical model describing the effects of impact head and hammer mass on the performance of the force transducer and experimental verification of this model are presented here.

Infantile myofibromatosis is a rare benign neoplasm which is usually found in males. Most cases of the infantile myofibromatosis are discovered before the age of two years and about half of cases are found at muscle, tendon, and soft tissue of head-neck region. However, it is especially uncommon that infantile myofibroma occurs at the pre-auricular area. In current case, we report a twenty two months old male patient with $2.5{\times}1.5cm$ sized pre-auricular mass at right side. It was surgically removed and histologically showed broad bundle of plump myoid spindle cells with eosinophilic cytoplasm and weakly positive smooth muscle actin expression in myoid cells. In three months of follow up, there was no recurrence.

A substrate specificity of cabbage phospholipase D (PLD) was studied using the synthetic phospholipids having different head groups. The phospholipids were synthesized from phosphatidylcholine and appropriate bases by transphosphatidylation of PLD. The bases used were ethanolamine, serine, ethanol and γ-hydroxybutyric acid. The phosphatidic acid, the product of PLD, was separated in TLC and measured densitometrically. The kinetic parameters were estimated for each substrate and the effects of pH, SDS, Ca2+ and other metal ions were examined. Vmax values found were 3.75, 2.36, 5.59, 1.63, 2.30 nmol/min/μg protein for phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylethanol, and phosphatidylburytic acid, respectively. These results indicate a broad specificity of cabbage PLD toward phospholipids with different head groups. Particularly phosphatidylserine was most easily hydrolyzed by PLD and its activity did not depend on Ca2+.

무선 센서노드들은 초기에 대량으로 랜덤하게 배치되어 스스로 클러스터를 구성하고, 각 클러스터 헤드 노드를 선출하여 정상적인 통신이 이루어져야 한다. 이러한 일련의 작업을 무선 센서노드 설치시 관리자가 직접적으로 관여할 수 없기 때문에 자가 구성 라우팅 기능이 가능하여야 한다. 논문에서 제안하는 통신영역을 고려한 클러스터 헤드 노드 선출 알고리즘은 계층구조를 형성하는 무선센서 네트워크 환경에서 적용되며, 베이스 스테이션의 통신 영역을 계산하여 클러스터 헤드 노드를 선정하고 클러스터를 구성한다.

1. Objectives The purpose of this case is to report that a Soeumin patient with cognitive disorder from traumatic head injury needed to be managed with the consideration of the difference of Nature and Emotion(性情). 2. Methods To evaluate the patient's cognition disorder and mental state, we performed the MMSE(Mini-Mental State Examination) and the MMPI(Minnesota Multiphasic Personality Inventory). and he was diagnosed as Soeumin and treated by Kwakhyangchungki-san(藿香正氣散) mainly. 3. Results and Conclusions (1) In this case, we observed specifically-biased Nature and Emotion(性情) of Soeumin like ‘恒欲處而不欲出’, ‘恒欲爲雌而不欲爲雄’, ‘喜別人之助己也’. ‘喜好不定’, ‘不安定之心’ (2) The management of Soeumin with cognitive disorder from traumatic head injury is that he or she should live together his or her family, and have an active manner with a generous and broad-minded mental attitude. (3) A therapist must give a patient mental support and inspire him or her with courage. (4) The deviation of Nature and Emotion(性情) should be taken into consideration when we manage the patient with cognitive disorder from traumatic head injury.
