The gluteal region is a frequent target for injecting high volumes. However, the safe intramuscular injection sites have been controversy in this region. This study was aimed to compare the subcutaneous fat and muscle thicknesses at the two gluteal injection sites and to determine the influence of sex and body mass index (BMI) on fat and muscle thicknesses.The ultimate purpose of this study is to suggest the most suitable intramuscular injection site among the ventrogluteal and dorsogluteal regions. Eleven fresh cadavers were injected with colored gelatin using syringes at the two gluteal injection sites.Seven variables were measured at both gluteal injection sites and analyzed relative to sex and the BMI. No variables showed statistically significant differences between the two gluteal injection sites according to sex. In a one-way analysis of variance, total length and muscle thickness had significant difference according to the BMI category. In obese cadavers, the injected gelatin core was located in the subcutaneous layer (average 109.0 percentile), and in the muscle layer (average 78.9 percentile) in the dorsogluteal region. These were found that the success rate of injection in the dorsogluteal region was higher than in the ventrogluteal region, especially when classed as obese. Also, it is suggested that nurses should use the traditional intramuscular injection method. It will also be necessary to consider expanding these findings to other ethnic groups in the Asia–Pacific region and then also education in universities and health providers on selecting the intramuscular gluteal injection site.

“Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” is the 3rd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 2nd edition published in 2014. Forty-two specialists in stroke rehabilitation from 21 universities and 4 rehabilitation hospitals and 4 consultants participated in this update. The purpose of this CPG is to provide optimum practical guidelines for stroke rehabilitation teams to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. The recent two CPGs from Canada (2015) and USA (2016) and articles that were published following the 2nd edition were used to develop this 3rd edition of CPG for stroke rehabilitation in Korea. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. Good Practice Point was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” consists of ‘Chapter 1; Introduction of Stroke Rehabilitation’, ‘Chapter 2; Rehabilitation for Stroke Syndrome, ‘Chapter 3; Rehabilitation for Returning to the Society’, and ‘Chapter 4; Advanced Technique for Stroke Rehabilitation’. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” will provide direction and standardization for acute, subacute and chronic stroke rehabilitation in Korea.

The most essential biological profiles in physical and forensic anthropology are age, sex, and populations to be determined. In case of dealing intact skeletons, experts can often determine sex with high accuracy. The external occipital protuberance (EOP) is one of the site among morphologic traits which is used to determine human sex. This study suggests the possibility to determine the sexual dimorphism using the EOP and surrounding anatomical structures in Koreans. After three-dimensional reconstruction of the skull model from Digital Korean Human Databse, the three parts were evaluated using a classification system based on Broca, Gulekon and Turgut. To determine for scoring, this study was used two in two different ways to observe the skull model; one was a lateral view and the other was turning the skull models. In a lateral view, the shape of the occipital area was classified as 'flat' or 'convex' type. After then the scores of the anatomical structures were converted into 4-digits code. In females, the skull was more convex in shape than males but the EOP and inion were lesser projection. In the lateral and turning views, the most common pattern was Type 2 in both sexes. The most common digit code was 2-2-2-0 in males, 2-2-2-1 in females. The digit code is better than simple scoring system for determining sex. The skull in Koreans were more feminine than in other populations in both sexes.

Most of foot pain occurs by the entrapment of the tibial nerve and its branches. Some studies have reported the location of the tibial nerve; however, textbooks and researches have not described the posterior tibial artery and the relationship between the tibal nerve and the posterior tibial artery in detail. The purpose of this study was to analyze the location of neurovascular structures and bifurcations of the nerve and artery in the ankle region based on the anatomical landmarks. Ninety feet of embalmed human cadavers were examined. All measurements were evaluated based on a reference line. Neurovascular structures were classified based on the relationship between the tibial nerve and the posterior tibial artery. The bifurcation of arteries and nerves were expressed by X- and Y-coordinates. Based on the reference line, 9 measurements were examined. The most common type I (55.6%), was the posterior tibial artery located medial to the tibial nerve. Neurovascular structures were located less than 50% of the distance between M and C from M at the reference line. The bifurcation of the posterior tibial artery was 41% in X-coordinate, -38% in Y-coordinate, and that of the tibial nerve was 48%, and -10%, respectively. Thirteen measurements and classification showed statistically significant differences between both sexes (P<0.05). It is determined the average position of neurovascular structures in the human ankle region and recorded the differences between the sexes and amongst the populations. These results would be helpful for the diagnosis and treatment of foot pain.

Nursing students will work to promote the health of patients as a nurse after graduation. Basic nursing science is to improve the quality and efficiency of nursing activity and to form the basis of nursing mandatory major. Anatomy is a curriculum of medical college, for that reason, it does not fit the characteristics of basic nursing science, and it is difficult to study mandatory major. This research was to provide basic data to be improved anatomy curriculum for nursing students using questionnaire about necessity of cadaveric dissection. Questionnaires were distributed to nursing students enrolled in anatomy course and professor taught basic nursing science in nursing college. Eighty-one percentage of nursing student and 95.5% in professor answered to need cadaveric dissection for nursing students. Nursing students answered that it should be helpful to understand about human body and nursing activity. Professors replied to acquire knowledge of human body and be of help to learn. They filled in internal organs and nervous system that have to observe during cadaveric dissection. The result of this research would be used as the basis for the improvement of anatomy curriculum in nursing college.

Sex determination is considered the first and most important process in the identification of unknown skeletal remains. The skull is one of bones with high accuracy to discriminate sexes, but there is no dimorphic studies of Korean skull by discriminant function analysis. The aim of this study was to build and provide an easy and accurate discriminant equation to sex determination by using three-dimensional skull images of Korean. Computed tomography images from 102 cadavers were reconstructed three-dimensional images by computer program. We measured 44 variables using the template in computer program and variables were sorted out items with high accuracy and reliability by intraclass correlation coefficient (ICC), Cohen's d value, and receiver operating characteristic (ROC) curve. The equation with the highest accuracy had 82.7% in males, 82.2% in females, it was constituted bizygomatic diameter, cranial base length, biauricular breadth, upper facial breadth, frontal chord, foramen magnum breadth, and right mastoid length. The cross-validated accuracy had 76.5%~86.7% using 3D skull images in Koreans. The value of variables that matches the other population group study, most of variables had a statistically significant difference among population groups. Male skulls in Koreans were smaller than those in European and female skulls were bigger than in Asian. This result should be helpful to determine sex in Koreans.

GyeongGi Cultural Foundation was requested the identification of eight excavated human skeletons from Neunggok residential development district within Siheung-si. Those were measured for distinguishing sex, stature, and age at death using metric and non-metric methods. The identification of eight human remains was not easy because the excavated bones were destroyed partly and totally. Six skeletons were excavated from the limed-soiled mixture tomb; five remains among 8 were buried in same grave and 2 skeletons were excavated from the earthen tomb. Four remains were determined female skeletons. One skeleton was assumed adolescence, three skeletons were estimated 40's~50's years old and others couldn't be done. Four among eight remain skeletons, the stature of female remains was around 150~157 cm and male's stature was around 165 cm. Most bones were damaged and destroyed, and the remaining teeth on the maxilla and mandible were not enough for identification. We couldn't identify through metric and non-metric methods. If the human skeletal remains were not found with artifact, those couldn't determine the period. So we couldn't know the relationship between the period of burial and condition of bones. For this reason, we will study the identification using the small and damaged bones. Anthropologists and archeaologists need to work together to make database to determine identification and period.

Forensic anthropology is helpful for correct and fast identification of unknown individuals in mass disaster or from unidentified skeletal remains. It is based on the data of the physical anthropology and applied to the identification in many countries. The purpose of this study is to statistically analyze the 290 forensic records by an office request at NISI during 6 years and to suggest the research model for physical anthropological data that would be helpful to be used at the forensic field. The most common excavated bone was a hard bone as skull and long bones and an unknown place was the most common excavation seat over 50% among the recording place. The probability of excavation with adjacent bone was high and the small sized bones, such as phalanges of hand and foot, were excavated rarely. The incomplete or fragmented bones were found more frequently than of complete. For this reason, we think that will show the priority order of the forensic and physical anthropologic studies in Korea and the necessity of the anatomical education for police officers and inspectors of forensic fields.

The embryologic origin of the omohyoid muscle is different from that of the other neck muscles. A number of variations such as the absence of muscle, variable sites of origin and insertion, and multiple bellies have been reported. However, variations in the inferior belly of the omohyoid muscle are rare. There have been no reports of the combined occurrence of the omohyoid muscle variation with the appearance of the levator glandulase thyroideae muscle. Routine dissection of a 51-year-old female cadaver revealed a duplicated omohyoid muscle and the appearance of the levator glandulae thyroideae muscle. In this case, the two inferior bellies of the omohyoid muscle were found to originate inferiorly from the superior border of the scapula. One of the inferior bellies generally continued to the superior belly with the tendinous intersection. The other inferior belly continued into the sternohyoid muscle without the tendinous intersection. In this case, the levator glandulae thyroideae muscle appeared on the left side, which attached from the upper border of the thyroid gland to the inferior border of the thyroid cartilage. These variations are significant for clinicians during endoscopic diagnosis and surgery because of the arterial and nervous damage due to iatrogenic injuries. The embryologic origins of the omohyoid and levator glandulae thyroideae muscles may be similar based on the descriptions in the relevant literature.

Rib seriation has not been used to identify individual human skeletal remains in Koreans. Accurate rib seriation is important for determining rib number and for establishing an individual's age at death. The aim of this study was to use a previously published quantitative method to correctly predict rib sequencing in Koreans. We used complete rib sets of 54 individuals and measured three variables: AFTAL (articular facet of the tubercle-toangle length), HAFL (head-to-articular facet length), and SCTCH (superior costo-transverse crest height). AFTAL and SCTCH were more useful than HAFL for predicting rib seriation, and AFTAL produced the simplest equation for determining sex. In the ranking, the cumulative percentage of AFTAL was 79% with an error of 0, and the range of seriation error was +/-4. Compared to other studies using European measures, AFTAL showed greater accuracy of rib seriation in this study of Korean ribs. In fact, both AFTAL and AFTAL with SCTCH accurately predicted rib 4 in 94% of cases. AFTAL was the most accurate, and use of both SCTCH and AFTAL yielded better results than either alone. Thus, the high accuracy and predictive ability showed that this method is useful for measuring rib seriation in Koreans.
