The author conducted an experiment using P-A Cephalography of 242 male and female subjects of ages ranging 2-6, 7-15, and adult group. By means of Nakago's method of measurement, the standard value of Korean was obtained. The results were as follows; 1. In the group of an age, the male value was greater slightly than female value. 2. In each age group the difference between the right and left widths could be recognizable, however, it was not much great. 3. In each group, regardless of sex, the growth relation was clearly distinguishable at PO, ARI, ARE, MG, AG, and CAW. 4. When the standard value of adult Korean was compared with that of Japanese, Japanese was great with respect to the width of maxillary portion and Korean was great with respect to the width of mandibular portion. 5. Maximum head width of white man was almost similar to that of Korean, however, maxillary alveolar base width of white man was considerably small or the dental arch was narrow.

The gravity measurement was conducted at 256 stations around Chungju Lake to study subsurface geological distributions and subterranean mass discontinuities by the results of gravity anomaly in Metamorphic Complex, Okcheon Group, Great Limestone Group of Choson Supergroup, and Cretaceous biotite granites. Okcheon Group showed a high Bouguer gravity anomaly while Great Limestone Group of Choson Supergroup relatively a low anomaly. The mean depth of subterranean mass discontinuities is about 2.0 km and downward along the Suchangri Formation from the Hwanggangri and Moonjuri formations. In general, Okcheon Group appeared shallower than the depth of Great Limestone Group of Choson Supergroup when imaging the subterranean mass discontinuities from the Bouguer gravity anomaly.

Purpose: The purpose of this study was to investigate the effects of active abduction exercise of the great toe on the medial and lateral sesamoid bones in hallux valgus (HV) patients by measuring radiography. Methods: In this study 27 young subjects were separated into two groups (normal group and HV group). Two pictures were taken by radiography while maintaining resting and while holding maximal active abduction of the great toe in sitting position on an x-ray table. All radiographs were used to measure the distance of the medial and lateral sesamoid bone from the longitudinal axis of the first metatarsal bone, respectively. Paired t-test was used for analysis of the resting and active abduction exercise in groups. Independent t-test was used to evaluate statistical significance between normal group and HV group. The statistical significance level was p<0.05. Results: In active abduction exercise of the normal group, distance of the medial and lateral sesamoid bones was not significantly different compared to resting condition. In active abduction exercise of the HV group, change of distance of the medial and lateral sesamoid bones showed statistically significant difference compared to resting condition. The distance between the medial sesamoid bone showed a more significant decrease in the HV vs. normal group, while the distance between the lateral sesamoid bone was significantly greater in the HV vs. normal group. Conclusion: These findings suggest that active abduction exercises, to reduce or prevent deterioration of the HV angle, should be considered for sesamoid bone displacement to improve muscle balance in the great toe.

We reviewed our entire experience of 44 consecutive patients undergoing the arterial switch operation [ASO] for transposition of the great arteries [TGA] since March 1985.There were 28 patients with simple TGA[group I] and 16 with associated ventricular septal defect[VSD] [Group II] There were five hospital deaths[11.4%, 5/44], two related to single right coronary artery anatomy. There have been no late deaths. For group I hospital mortality was 14.3%[4/28], and for group II this was 6.25%[1/16]. Mean follow-up was 3.3 years[range 1 month to 8 years] and was completed for all patients. Actuarial survival at 7 years for hospital survivors was 85 $\pm$ 3.2 % in group I and 94 $\pm$ 3.5% in groupII. One patient has mild asymptomatic left ventricular outflow tract obstruction, and five patients [12.8 %,5/ 39] have right ventricular outflow tract gradients[RVOTO] exceeding 25 mmHg; only one patient has required reoperation for RVOTO. Mild neoaortic regurgitation is present in one patient. All survivors are currently in NYHA class I without medicalion, and all are in sinus rhythm. The ASO is associated with low operative risk and excellent medium-term outcome in most subsets of patients undergoing this operation. With more experience, improved results can be expected also in those patients currently at higher risk.

The study area is located in between Hacheonri and Weolgulri, Jecheon-gun where the formations of Okcheon group and Chosun group come in contact and the stratigraphy and geological age of the Okcheon group have been debated among previous workers. The dolomitic limestone which distributed at Cheongam and Dumusil is clarified as the Hyangsanri dolomite formation and the quartzite distributed at Cheongam and Howeunri as Taehyangsan quartzite formation. The newly named Soorumsan schist interbedded in the Great Limestone Series was previously classified Seochangri formation. It is also classified that the formation formerly named as Seochangri was divided into newly named Manji schist which seems to be correlated to Kemyeongsan and Munjuri formation. The formation formerly named as Buknori is clarified as Hwanggangri formation. The Samtaesan formation has been clarified as the lower and upper limestone beds which belong to the Great Limestone Series. The area divided into two groups, that is, Okcheon system of Pre-cambrian age occupies western part and the Great Limestone Series of Chosun system of Cambro-Ordovician age eastern part of this area. Okcheon system consists in ascending order of Manji schist, Hyangsanri dolomite, Taehyangsan quartzite, Munjuri schist, and Hwanggangri formation of meta-tillite. The Great Limestone Series of Chosun group consists in ascending order of lower limestone, Soorumsan schist, Hoosanri quartzite and upper limestone formations. Busan augen gneiss seems to be igneous origin. Unmetamorphosed shale interbed can be traced in the Soorumsan schist. Previous study (Kims, 1974) reveals that meta-volcanic rocks are distributed from south to north along contact zone of the Okcheon and Chosun groups, and it has been confirmed that the meta-volcanics crop out continuously from the adjacent southern quardrangle into the southern part of the area studied, intruding along the fault zone between the Okcheon and Chosun groups which seems to be upthrust as in the area south. This evidence coincides with Kims' work (1974) which states that the Precambrian Okcheon group is largely overturned and thrusted over the Chosun group.

Purpose: This single-center study aimed to assess the clinical features and surgical approaches and outcomes of complete transposition of the great arteries (TGA). Methods: TGA patients who had undergone surgical correction at the Kyungpook National University Hospital from January 2000 to December 2010, were retrospectively evaluated for patient characteristics, clinical manifestation, preoperative management, intraoperative findings, postoperative progress, and follow-up status. Results: Twenty-eight patients (17 boys and 11 girls, mean age=$10.6{\pm}21.5$ days) were included and were categorized as follows: group I, TGA with intact ventricular septum (n=13); group II, TGA with ventricular septal defect (VSD, n=12); and group III, TGA/VSD with pulmonary stenosis (n=3). Group I underwent the most intensive preoperative management (balloon atrial septostomy and prostaglandin E1 medication). Group II showed the highest incidence of heart failure (P<0.05). Usual and unusual coronary anatomy patterns were observed in 20 (71%) and 8 patients, respectively. Arterial and half-turned truncal switch operations were performed in 25 and 3 patients (Group III), respectively. Postoperative complications included cardiac arrhythmias (8 patients), central nervous system complications (3 patients), acute renal failure (1 patient), infections (3 patients), and cardiac tamponade (1 patient), and no statistically significant difference was observed between the groups. Group II showed the mildest aortic regurgitation on follow-up echocardiograms (P<0.05). One patient underwent reoperation, and 1 died. The overall mortality rate was 4%. Conclusion: Our study showed favorable results in all the groups and no significant difference in postoperative complication, reoperation, and mortality among the groups. However, our results were inadequate to evaluate the risk factors for reoperation and mortality owing to the small number of patients and short follow-up duration.

This study is aimed at identifying China's land operating system in the great leap periods. the findings are as follows. For one thing, though the landownership in China was basically performed in public, a portion of private management was allowed. The more this kind of private management allowed, the more the life standard of farmers enhanced. For another thing, the conversion from agricultural cooperatives to people's commune happened swiftly, and the problems according to the conversion arose instantly, which made the operation system changed partially. The last, but not the least, even in the point of the rapid communistic movement, private management was locally accepted in the name of three self and one private management. Besides, as we can recognize from the case study of Daichai village, the operation of a large working group and a small working group was done in political context.

In the quickly developing world, the idea of the conventional advancement needs to advance[1]. When applied to the advanced work environment, the conventional strategies give as much damage as they do great. Tragically, an absence of versatility in the customary techniques has prompted an inflexible work structure that is truly not viable with the present business. The Agile technique is, subsequently, a more adequate practice, in view of creating programming at a faster speed, while as yet looking after proficiency. The coordinated programming improvement strategies are concentrated in this paper. As per study results, Agile software development group needs solid client association; great light-footed task the executives' measures; item proprietor expands business esteem conveyed by group and need and draw in partners; great deft designing procedures or practices; and great advancements and advancement apparatuses[2]. This examination has suggestions for positive social change since associations that comprehend the basic components might have the option to improve project the executives' systems and money saving advantages prompting higher effectiveness, productivity, and efficiency hence profiting the board, representatives, and client. This survey paper incorporates various methodologies of Agile and their analysis.
