The exocrine part of the pancreas has a duct system called the pancreatic ductal system (PDS). Its mechanism of development is complex, and any reorganization during early embryogenesis can give rise to anatomical variants. The aim of this study is to collect, classify, and analyze published evidence on the importance of anatomical variants of the PDS, addressing gaps in our understanding of such variations. The MEDLINE, Web of Science, Embase, and Google Scholar databases were searched to identify publications relevant to this review. R studio with meta-package was used for data extraction, risk of bias estimation, and statistical analysis. A total of 64 studies out of 1,778 proved suitable for this review and metanalysis. The meta-analysis computed the prevalence of normal variants of the PDS (92% of 10,514 subjects). Type 3 variants and "descending" subtypes of the main pancreatic duct (MPD) predominated in the pooled samples. The mean lengths of the MPD and accessory pancreatic duct (APD) were 16.53 cm and 3.36 cm, respectively. The mean diameters of the MPD at the head and the APD were 3.43 mm and 1.69 mm, respectively. The APD was present in only 41% of samples, and the long type predominated. The pancreatic ductal anatomy is highly variable, and the incorrect identification of variants may be challenging for surgeons during ductal anastomosis with gut, failure to which may often cause ductal obstruction or pseudocysts formation.

PURPOSE: The purpose of this study was to investigate the vital capacity and maximal voluntary ventilationin subjects with forward head posture (FHP). METHODS: Twenty-eight subjects participated in this study (normal 14, FHP 14) and were resident in B city. The mean age, height and weight of subjects was 22.80yrs, 169.36cm and 62.79kg. Subjects were asked to breath maximally for FVC and repeatedly for MVV during 12 seconds. The variables of data were collected as follows: Forced Vital Capacity(FVC), Forced Expiratory Volume in One Second($FEV_1$), $FEV_1$/FVC, Maximal Voluntary Ventilation(MVV). Each trial was performed by 3 times and we used the means to analyze the data. The mann-whitney U test and independent t-test were used to compare the vital capacity between normal and FHP subjects. All statistical analyses were performed using SPSS 21.0 for window versionand p-values less than 0.05 were used to identify significant differences. RESULTS: The FVC, $FEV_1$, $FEV_1$/FVC and MVV of FHP subjects were decreased more than that of normal subjects and the difference was statistically significant between two groups. CONCLUSION: The vital capacity of subjects with FHP was generally lower than normal subjects. This study shows that the vital capacityof subjectswith FHP could be decreased due to the bad neck posture that weakens the respiratory accessory muscles of neck.

Purpose: Parotid neoplasia are relatively frequent, representing approximately 3% of all tumors in the head and neck regions. But incomplete resection and misdiagnosis of parotid gland is followed by multiple tumor invasion, tumor recurrence, and other iatrogenic tumor formation. In patients undergoing parotidectomy for confirmed or suspected malignancy, the traditional or modified rhytidectomy incision may prove suboptimal because it does not easily lend itself to a continuous neck dissection. Similarly, patients with tumors of the anterior accessory lobe or patients with large anterior tumors may also require the modified Blair incision for adequate surgical exposure. This report serves to revisit the topic of accessory and parotid gland neoplasms to emphasize proper management, particularly the surgical aspects, so that consequences of recurrence are avoided. Methods: This is a retrospective review of our experience with two cases of parotid tumors; one accessory parotid gland neoplasm and one parotid gland neoplasm. We report the case of parotid tumor and epidermal cyst in a 54-year old male patient and the case of case of recurrent parotid tumor with local invasion in 30-year old male patient. Results: All were removed through a modified Blair incision. Pathologic report notified that One was found pleomorphic adenoma and epidermal cyst, and the other one pleomorphic adenoma with subcutenous invasion. The patients recovered well without any complication such as infection, hematoma, facial nerve palsy, and necrosis of skin flap. Patients were discharge POD#7. Patients were followed up to for 1 year and they have no sign of recurrence. Conclusions: A high index of suspicion, prudent diagnostic skills(including fine-needle aspiration biopsy, CT, US), and meticulous surgical approach are the keys to a successful management of these lesions. We experienced two cases of parotid neoplasia, in the treatment of tumor reccurence & iatrogenic tumor arising from the parotid gland and are presented with the review of literatures.

The techniques of joint mobilization and traction are used to improve joint mobility or to decrease pain by restoring accessory movements to the shoulder joints and thus allowing full, nonrestriced, pain-free range of motion. In the glenohumeral joint, the humeral head would be the convex surface, while the glenoid fossa would be the concave surface. The medial end of the clavicle is concave anterioposteriorly and convex superioinferiorly, the articular surface of the sternum is reciprocally curved. The acromioclavicular joint is a plane synovial joint between a small convex facet on lateral end of the clavicle and a small concave facet on the acromion of the scapula. The relationship between the shape of articulating joint surface and the direction of gliding is defined by the Convex-Concave Rule. If the concave joint surface is moving on a stationary convex surface, gliding occur in the same direction as the rolling motion. If the convex surface is moving on a stationary concave surface, gliding will occur in an opposite direction to rolling. Hypomobile shoulder joints are treated be using a gliding technique.

Three newly recorded rotifers were collected through surveys of several islands in Korea: Lecane perplexa (Ahlstrom, 1938); Lindia torulosa Dujardin, 1841; and Monommata maculata Harring & Myers, 1930. These species represent 24th, second, and third records of each genus discovered in Korea, respectively. Lecane perplexa and Monommata maculata, were collected from reservoirs using plankton nets, whereas Lindia torulosa was collected from a soil sample. The morphological characteristics of the discovered species are as follows: Lecane perplexa is characterized by a straight or slightly concave anterior margin of the lorica, an incomplete transverse fold on the ventral lorica, and a single toe with pseudoclaws and accessory claws; Lindia torulosa has an illoricated and vermiform body, a head with rostrum, a pair of auricles, cardate type trophi, and distinctively shaped epipharynx components; and Monommata maculata is characterized by long toes, an inner margin of rami with 10-12 serrated teeth, 3-4 large teeth, and interlocking teeth. Here, the morphological characteristics of the three Korean monogonont rotifers, which include trophi photographs, are presented. In addition, partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) of each species are presented.

One of the suprahyoid muscles is the digastric muscle which comprises anterior and posterior bellies joined by an intermediate tendon. Because of its close relationship with the submandibular gland, lymph nodes, and chief vessels of the neck, detailed knowledge about the morphometry of the digastric muscle is essential. The objective of the current cross-sectional evaluative study is to record morphometry along with the digastric muscle's origin, insertion, and variability. Forty human cadavers (25 males and 15 females) were dissected, and the head and neck regions were studied in detail. The attachment of the digastric muscle anterior belly to the digastric fossa of the mandible was noted, and the distal attachment of the posterior belly to the mastoid notch was traced. The length of the anterior belly from the digastric fossa to its intermediate tendon and the length of the posterior belly from the intermediate tendon to its mastoid attachment were measured. There is a fair correlation between the length of the neck and the length of the anterior and posterior belly. The study also identified two cases of bilateral accessory bellies of the anterior belly of the digastric. Normal morphometric data is provided by this study on details of the digastric muscle. It is significant from a clinical and surgical point of view as the muscle lies in proximity to the important structures of the neck.

The purpose of this report Is to discribe the radiological findings of traumatic elbow luxation and subluxation of carpal joint which were caused by being hit by a wild animal and forced hyperextension of carpus in two hunting dogs. In case 1, carniocaudal and mediolateral radiographic examination of the elbow joint revealed that the radius that the radius and ulna were completely luxated laterally. The lateral projection showed the humeral condyles overlying the radial head with an absent joint space, but displacement is apparent on the craniocaudal projection. Incidence of collateral ligament rupture in conjunction with elbow luxation was not recognized on physical examination of the limb after closed reduction. Radiographic examination of the elbow made 5 months after closed reduction revealed only mild degenerative joint disease. Radiographic examination of the carpus in case 2 demonstrated palmar subluxation of most carpal joints including antebrachiocarpal, mediocarpal carpometacarpal joints, and some intercarpal joints, and avulsion fracture of the palmar surface of the accessory carpal bone. However, the mediocarpal and carpometacarpal joints were most severely affected by tensile forces of hyperextension, and it was concluded that the ligaments of the middle ca,pal joints and carpometacarpal joints as well as the palmar fibrocartilage were ruptured based on clinical and radiographic findings. In elbow luxation and subluxation of carpal Joints of the dog, differentiation of the joint or joints involved, and ligamentous structures damaged is important in determining whether surgery Is necessary and which procedure is most appropriate. And the radiographic findings of these conditions would be of help to practitioners.

Specific interaction of the epsin N-terminal homology(ENTH) domain with the plasma membrane appears to bridge other related proteins to the specific regions of the membrane that are invaginated to form endocytic vesicles. An additional $\alpha$-helix, referred to as helix 0 (H0), is formed in the presence of the soluble ligand inositol-1,4,5-trisphosphate [$Ins(1,4,5)P_3$] at the N terminus of the ENTH domain (amino acid residues 3-15). The ENTH domain alone and full-length epsin cause tubulation of liposomes made of brain lipids. Thus, it is believed that H0 is membrane-inserted when it is coordinated with the phospholipid phosphatidylinositol-4,5-bisphosphate [$PtdIns(4,5)P_2$], resulting in membrane deformation as well as recruitment of accessory factors to the membrane. However, formation of H0 in a real biological membrane has not been demonstrated. In the present study, the membrane structure of H0 was determined by measurement of electron paramagnetic resonance (EPR) nitroxide accessibility. H0 was located at the phosphate head-group region of the membrane. Moreover, EPR line-shape analysis indicated that no pre-formed H0-like structure were present on normal acidic membranes. $PtdIns(4,5)P_2$ was necessary and sufficient for interaction of the H0 region with the membrane. H0 was stable only in the membrane. In conclusion, the H0 region of the ENTH domain has an intrinsic ability to form H0 in a $PtdIns(4,5)P_2$-containing membrane, perhaps functioning as a sensor of membrane patches enriched with $PtdIns(4,5)P_2$ that will initiate curvature to form endocytic vesicles.

SOO-BAL(Hair Style) is a method Which match hair style to face and clothes with using hair covering and protecting the head. Also SOO-BAL includes personal ornaments using to avoid one's hair be disheveled. In a standpoint of beauty and spirit, etiquette SOO-BAL is a very important thing as one being dressed up. Until now, since just a form of hair style have been studied, hair styling process is nothing to be known and studied. Time after time, our unique traditional SOO-BAL is forgotten with clothes and then this th-esis will be classified hair styling form follow-ing a form of hair style in royal palace of the C-hosun dynasty. According to the record of HAE DONG HISTORY, it shows the same of attire between Ko-rean and chinese style in ae of the chosun. The reason in that there were no any certain boundary border and the interaction of culture between two countries was happened spontaneously at ancient time like the GOCHO-SUN age. Until the period of the three states, the korean attire be changed had gone with chinese one s-imilarly. The chinese form gave to influence on the EONJIN MEURI·POON-GI-MYEONG MEURI·JJO-CJIN MEURI·MOOK-EUN GOONG-BAL MEURI·OL-LIN MEURI·SSANGSANG-TU ME-URI be drawn wall painting in the KOKUR-YU. And a gold chignon accesso-ry unearthed in a MOO-RYOUNG royal mausoleum is proof of the korean attrire be changed with chinese. In the shilla dynasty at three years after Cjin-Deuk(A.D. 649) reign. It was recorded that the dynasty let women wear the form of chinese attire. Also in the koryo dyn-asty, a rod-like hairpin (BIN-YEU) and DANG-GI employing EON-JIN MEURI was used. The SOO-BAL based on the Confucianism had lots of regulations which limited to use ornaments with classes of society in the CHOSUN dynasty. Until YOUNG CHO and CHUNG CHO period. EONJIN MEURI be decorated GACHAE was announced by dynasty as ind-ulging in luxury. Women of yangban used a rod-like hairpin and a chignon accessory made by jewerly. And 1-owly women weared a rod-like hairpin made of born and wood to perfom EONJIN MEURI with PUNCHAE. Most unmarried women decorated with DDA-AH-NEULIN MEURI, GUI-MIT MEURI, specially in palace with SAE-ANG MEURI. At palace, one put on a full dress with KEUN MEURI, and a simple dress with ER-YEO MEURI be decorated DDERL-JAM The CHOP-JI MEURI manifested social rank, class. Kids at CHO-SUN age had BA-DUK-PANMEURI and JONG-JONG MEURI. The ornament things are GACHE, DDERL JAM with EON-JIN M-EURI, and all kinds of rod-like hairpin and chignon accessory used in JJOK MEURI. IN DANGGE, JE-BI-BURI DANGGI used by ummarried women. DO-TOO-RAK DANGGI and AP DANGGI on a dress suit, and BE-SSI DANGGI used by 3∼4 years ungrown kids etc. were used. And at palace, kinds of CHUPJI used with JJOK MEURI showed social rank. In CHOSUN age, women want to keep shiny hair washed at TA-NO festival day, a treatment of bald hair used a forked remedy. In CHOSUN age, woman Soo-Bal hair style has DAE-SOO·DDEU-KOO-JI MEURI·CHO-P-GI MEURI·EON-JIN MEURI·SAE-ANG MEURI· and so on. We could find out Soo-Bal was developed very well by these variety hair styles. I attatched all of the hair style pictures step by step, and also explained detail my research foll owing these pictures.
