${\delta}^{13}C$ and ${\delta}^{18}O$ values were determined for the Paleozoic limestones (Great Linestone Series) from the Taebaegsan region and the age-unknown limestones (Janggun Formation) from the Janggun mine, Korea. Limestones of the Great Limestone Series exhibit a range of carbon isotopic composition from -4.5 +1.3‰ with a mean ${\delta}^{13}C$ value of -1.1‰, relative to the PDB standard, and of oxygen isotpic composition from +8.8 to +23.3‰ with a mean ${\delta}^{18}O$ value of +16.0‰, relative to the SMOW, falling into the normal marine limestone range according to Keith and Weber (1964), and Degens and Epstein(1964). Carbon isotopic composition of limestones of the Great Limestone Series becomes progressively lighter from Pungchon limestone of middle Cambrian age to mid-Ordovician Maggol limestone, possibly due to change in depositional environment in the Taebaegsan basin. Variation in isotopic composition of limestones from Hwajeol to Dumugal formation offers the possibility or deposition in shallow sea environment, in which fresh waters were added in several stages. Janggun limestone of unknown age may be corelated with the Paleozoic limestones of Great Limestone Series as infered from the istopic composition ranging from -2.8 to + 0.7‰ of ${\delta}^{13}C$ and +13.4 to +22.4‰ of ${\delta}^{18}O$.

The recent Great Recession of 2008 was a period of sharp economic decline throughout the late 2000s. All socio-demographic groups were impacted by the economic downturn, however, Hispanic households were particularly hard hit. It is not a recent phenomenon that minority groups often have greater problems related to credit and debt repayments. A better understanding of these racial/ethnic differences in credit and debt has been hindered by the propensity of many studies to pool all racial/ethnic minorities together and compare them to white households. Using a Heckman-type selection model with a combination of the 2010 and 2013 Survey of Consumer Finances datasets to study household debt repayment problems, we found that racial/ethnic groups have been differently impacted by the recent Great Recession in terms of debt repayment problems. Hispanic households were less likely to hold debt; however, those with debt were just as likely as white households and African American households to be delinquent in repayments. This finding is contrary to prior research that indicated Hispanics with debt were less likely than white and African American households to be delinquent on repayments prior to the Great Recession of 2008. We propose possible explanations for the increase in debt repayment problems, that includes increased assimilation into the U.S. culture of credit use, the circumstance of being more recent home buyers prior to the decline, and living in states that suffered the greatest decline in housing value.

The Bell King Songdok the Great tolls magnificient sound that would be a great vehicle which brings all beings to the Sutras. Since 693, there was a magic flute, MANPASIKJUK, which was in existence in Shilla Dynasty that could lull all the evil-wawes, such an plaques, storms, Droughts, Famines and even Enemies. Thus, a sound tube, MANPASIKJUK, was erected in the crown of the Bell Songdok the Great so as to be effective to emit the nominal frequency tone whenever the Bell tolls for the national prosperity and welfare the People. Therefore, the Bell makers tried to fine the transmissibility condition through the sound tubr, several times during 34 years, However, it seems to be unfinished. Ever since, all of the korean Brahman Bell have the sound tubes of MANPASIKJUK, but none is performed their own functions. Here, one of the way to let the function of the sound tube of MANPASIKJUK out in the Bell Songdok the Great is proposed. There are two steps: the 1st is to elongate 18cm to the present length 77cm to fulfill the transmissibility condition for the nominal frequency of sound is emitted through the corrected sound tybe. 2nd step is to rise to 95% of the emission of the tone of nominal frequency, so that an exponential hem with the flare constant 2.8m-1, length 2.259m and the radius of the mouth 1.772m is to be extended to the corrected sound tube.

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.

Purpose: The purpose of this study was to present the clinical analysis of the results and our experience of the replantation surgery of the great toe. Materials and Methods: Between March 1995 and December 2002, twelve great toes, amputated from the distal phalanx to proximal phalanx were replanted. The complete types were 5 cases and incomplete types were 7 cases. The guillotine injuries were 4 cases and the crushing injuries were 8 cases. Results: Replantation in eleven out of the twelve amputations survived. The cases of revision were 3 cases due to venous thrombosis. Patients were followed up for a mean period of 2.2 years. The mean total active motion of the first MTP joint was $80^{\circ}$. The fusion of IP joint was carried in 7 cases due to the amputation of the IP joint level. The shortening of the replanted great toes was present, with average 0.9cm. The two point discrimination was 7-8mm except 2 cases with loss of nerve. Conclusion: Although replantation of the great toe remains to be controversial, replantation of the great toe should be considered in well-motivated patients because successful replantation regains an important component of the foot and good functional, cosmetic results.

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.

This purpose of present study was to examine the figures and colors of hanbok textile. The data were collected from 489 pieces selling at hanbok shops in Taegu pusan and were analysed. Result of this study was as follows: 1) Figures As the hanbok figures tradition figures were used a great many among the figures. The next was natural geometric abstract figures. The reactionism trend was worthy of notice in figures and traditional design occupied most of them. 2) Color In the hue, YR, R, RP group were used concentratedly. Because 5,6,7 level were used a great many among the value value was represented lightly more than midium light. Because 2,3,4 level were used a great many among the chroma chroma was represented duller than midium chroma. Thus hanbok color was used mainly in a several party and korean were tendancy to like natural the sence of color.

Various interpretations on the boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system, and on the geologic structure and stratigraphy of the $Okch{\check{o}}n$ system have been yielded by the previous studies, and they are still in hot debate. The present work has mainly studied on the boundary between the $Okch{\check{o}}n$ and $Chos{\check{o}}n$ systems in the south of $Jech{\check{o}}n$, and the geology in its vicinity to clarify the previous misinterpretations if any on the geologic structure and in trun stratigraphy of the area concerned. The boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system has been thought to be (1) gradational relation which means two systems are the same formation, (2) unconformable relation in which the $Okch{\check{o}}n$ system overlies the $Chos{\check{o}}n$ system, (3) unconformable relation in which the $Chos{\check{o}}n$ system overlies the Okchon system indicating that the age of the $Okch{\check{o}}n$ system is Precambrian, and (4) fault contact in which the $Okch{\check{o}}n$ system of Precambrian age comes in contact with the $Chos{\check{o}}n$ system of Cambro-Ordovician age. The present study clearly found that the relationship between the two systems is a fault zone contact. Shear zone of a width of 300 to 400m is developed, and andesitic volcanics and basic dikes are intruded along the fault zone. This fault contact is exactly the north extension of the Bonghwajae fault, which was denominated long time ago by two of the present authors. The eastern side of the fault has been uplifted so that the $S{\check{o}}changri$ formation of the $Okch{\check{o}}n$ system cropped out in the zone of the Great Limestone series. All the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, but the present study found an overthrust having a strike of $N8^{\circ}E$ and dip of $30^{\circ}NW$ between them, and the $S{\check{o}}changri$ formation has thrusted over the Great Limestone series at the central part of the study area. In the southern and northern parts of this uplifted $S{\check{o}}changri$ formation, the Great Limestone series rests unconformably on it. In the eastern part of the study area where the Mt. Dangdu is located and the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, Precambrian basement rock whose age is older than 1720+50 m.y. crops out in the northern part of the east-west trending high angle fault, and the Great Limestone series rests unconformably on the basement.

The present research aims to consider the real remains of 2 suits of Kasaya owned by the Hwaeom Temple(華嚴寺) based on research results about Kasaya in the meanwhile. The present research on 2 suits of remains which are Royal gifts given to monk soldiers in case of a national crisis of the Joseon Dynasty has a big meaning in examining characteristics of Kasaya and grasping characteristics and structure of the 17th century's Kasaya of the Joseon Dynasty through dense survey and analysis according to components. If examining characteristics of Kasaya, the Kasaya of the Great Monk Seo San(西山) is composed on the basis of an initial form of Sun and Moon Light Patch's generation and the Kasaya of the Great Monk Byeok Am(碧巖) has a form that is separately attached through production of embroidery patch as a process of being settled down. If examining what surrounds gold thread in the girth and expression of Sumeru and Chaeunmun(彩雲紋), the composition of a form similar to an insignia badge, so because this is a Royal gift, this can be estimated as being analyzed in a Buddhism aspect by devising a design from the insignia badge at the time, with a meaning like an official uniform given to a monk. Although the insignia badge is a square, it seems that the Sun and Moon Light Patch is made as a rectangular form corresponding to the structure of Kasaya. In addition, it is thought that what the Samjoko(三足烏) idea which is a symbol of the Sun based on Buddhism and Taoism is used together with Yijoko(二足烏) even in expression of the Sun and Moon Light Patch in the Joseon Dynasty which was a Confucian country has a relationship with what a bird was expressed in the insignia badge of winged animals.
