To design a beautiful hood fitting an unspecific individual, focusing on body parts such as the head, neck and shoulder requires body size and type information, which applied by physical factors like size, types, and movements, etc. These parts consist of complicated types and structures. Accurate information should be a priority due to great individual differences and low correlation with other body parts. However, there is not a lot of detailed physical information nor design methods for hood design. Therefore, the purpose of this study is to select a study sample "hood" which is a recently emerging fashion item and to expand the necessary physical information for pattern design and draw body size of wearing part on Hood like head, cerbical portion and shoulder. Extract factors to consist on types and after divided into several types, a study comparing each type's physical characteristics was conducted. In order to do that, body measurement data have been collected by statistical treatment and analyzed reference with statistical treatment. The results of the study are predicted to be important data to develop various hood designs for the recent fashion trend. Factor analysis was conducted through main composition analysis about direct measured item on human body and index items. The results of factor analysis, composed factors of body type in this research object were extracted in total of 3 factors. To categorize the head, neck and shoulders of women in their early 20s women and determine their characteristics, variances with factor analysis became operative for Cluster analysis. With these clusters, women in their early 20s were categorized into three types. The results of this study are considered to affect largely for higher physical suitability on unspecified individuals when allowed absence of reference and the fact that body size only limited to item 'head circumstance' in terms of making hat and hood in the case of recent Korea. For the future, an experimental study of hood production should be conducted by using basic data from this study.

This study was to examine Kwa-Jung-ryu, a traditional Korean confectionery, made by head families. We examined the materials and recipes of Kwa-Jung-ryu, which were classified into Yumilgwa, Yugwa, Jeonggwa, Dasikgwa, Yeot-Gangjeong, Dang (Yeot), and others. There were 13 head families that introduced Kwa-Jung-ryu, two each from Gyeonggi-do, Jeolla-do, and Chuncheong-do, and seven from Gyeongsang-do. There are 33 types of Kwa-Jung-ryu, which averages to about 2.5 types per family. But the Pungsan Ryu, Yeoju Lee, and Andong Kwon families introduced the most Kwa-Jung-ryu with 5 types each. The most popular types of Kwa-Jung-ryu were Yumilgwa, introduced by 7 families (Yakgwa by 6 and Maejakgwa by 1), then Jeonggwa by 6 families (Jeonggwa by 3, Pyeon-gang by 1, and Jeonggwa and Pyeon-gang by 2), and Dasikgwa and other Kwa-Jung-ryu by 5 families (Gotgam-mari by 4 and Seopsansam by 1). Classifying Kwa-Jung-ryu by recipe, the most frequently introduced were 8 types of Jeonggwa-ryu, 7 types of Yumilgwa, 5 types of Dasikgwa, 3 types of Yeot-Gangjeong and Dang (Yeot), and 2 types of Yugwa.

This study analyzes the form of sleeve heads, which is an important internal element that affects the appearance of jacket sleeves. It characterized sleeve head forms by investigating angles, materials, and a combination of formations for 50 sleeve heads. It conducted an appearance evaluation by comparing and analyzing the results. This paper develops a sleeve head appropriately for sleeve construction. The study results are as follows. First, the product was divided into three parts: based on, force receiving, and sleeve cap parts. There were four types of man's sleeve head: straight, arc, and curve A and B types. The woman's sleeve head had two types: straight and curve B type. Second, the feature of each type of sleeve head was analyzed. A straight type emphasized the based on part. An arc type highlighted the force receiving part while the based on part decreased. The sleeve cap part, force receiving part, and based on part were emphasized in the arc type sleeve head. Third, as a result of the appearance evaluation, each type was rank as straight type < arc type ${\leq}$ curve A < curve B. The straight type did not get positive results as it had extra ease when the sleeve head was attached to a Jacket Sleeve. The arc type was evaluated poorly due to an inappropriate sleeve cap composition. The curve type received an excellent overall outcome as it fit into the sleeve cap part well and highlighted the force receiving part in order to minimize front and back wrinkles. Therefore, the curve type made the resemblance of the jacket appearance perfect and closest to the sleeve pattern.

Human papillomaviruses (HPVs) remain a serious world health problem due to their association with cervical and head and neck cancers. While over 100 HPV types have been identified, only a few subtypes are associated with malignancies. HPV 16 and 18 are the most prevalent oncogenic types in head and neck cancers. Although it has been proven that some subsets of benign and malignant head and neck lesions are associated with HPV, the general population have very little awareness and knowledge of their association with HPV. Therefore, the purpose of this study was to determine the knowledge of HPV and its links with head and neck benign and malignant lesions in a group of Pakistani dental patients who attended the Dental Department of the Sandeman provincial hospital in Quetta, Pakistan. One hundred and ninety-two patients were recruited and requested to answer a questionnaire. It was revealed that there was a low level of knowledge about HPV and its association with head and neck benign and malignant lesions among the participants. This result suggested that more education regarding the relationship of HPV in inducing head and neck benign and malignant lesions is required in this group of patients.

There are various types of flap in head and neck reconstruction. We chose the appropriate flap considering the indication and patient's condition. In case of conventional flaps, its type is decided according to the reconstruction site. In other words, the types of considerable flaps are limited in a way. But, perforator flaps can reduce donor limitation and harvest flaps depending on the condition of the recipient. Therefore, the flap is very useful for the head and neck reconstruction needed for 2-dimensional or 3-dimensional reconstruction. We report the 29 cases of perforator-based flap including 8 cases of latissimus dorsi perforator free flap, 5 thoracodorsal perforator free flap, 4 anterolateral thigh perforator free flap, 3 peroneal osteocutaneous perforator free flap and 9 submental perforator island flap for the head and neck reconstruction. Free flaps include 2 cases of chimeric pattern, 7 controlled resurfacing pattern, 4 3-D pattern, 3 dermoadiposal pattern, 1 folded pattern and 3 osteocutaneous pattern. The flaps were successfully used for the head and neck reconstruction. But one patient died during a follow up period because of the recurrence of tumor. Various perforator flaps(island/free pattern) can be highly competitive to the conventional flaps in the head and neck reconstruction, considering a thin character for resurfacing, more flexible and versatile option, variable composition, long pedicle with donor structures saved, and less prominent donor morbidity.

Purpose: The aim of this study was to introduce a method of obtaining the oscillation graphs of the dental x-ray tube heads relative to time using an accelerometer. Materials and Methods: An Accelerometer, Piezotron type 8704B25 (Kistler Instrument Co., Amherst, NY, USA) was utilized to measure the horizontal oscillation of the x-ray tube head immediately after positioning the tube head for an intraoral radiograph. The signal from the sensor was transferred to a dynamic signal analyzer, which displayed the magnitude of the acceleration on the Y-axis and time lapse on the X -axis. The horizontal oscillation of the tube head was measured relative to time, and the settling time was also determined on the basis of the acceleration graphs for 6 wall type, 5 floor-fixed type, and 4 mobile type dental x-ray machines. Results : The oscillation graphs showed that tube head movement decreased rapidly over time. The settling time varied with x-ray machine types. Wall-type x-ray machines had a settling time of up to 6 seconds, 5 seconds for fixed floor-types, and 1 I seconds for the mobile-types. Conclusion: Using an accelerometer, we obtained the oscillation graphs of the dental x-ray tube head relative to time. The oscillation graph with time can guide the operator to decide upon the optimum exposure moment after x-ray tube head positioning for better radiographic resolution.
