The development of idyllic housings, is in increasing growth in the suburban areas of Seoul, presents some critical problems such as in sufficient common open space and poor living condition, which are mainly caused by disorderly designed. Through comparing planning indices of idyllic housing, this paper aims to diagnose the condition and causes of those problems and to present some basic issues on improvement direction. The causes of problems can be summarized as the blind point in regulation system, the shortness of planning elements of a housing block which includes road systems and public facilities, and the mismatch of housing type with density, on which includes road systems and public facilities, and the mismatch of housing type with density, on which hereafter improvement suggestion should be focused. And this study suggest the simulation models on an ideal idyllic housing to be applied in our forthcoming idyllic housing of Korea, which can indeed become a generalized alternative to the livable idyllic housing.

Meconium peritonitis is a primarily aseptic, chemical peritonitis caused by the spill of meconium into the abdominal cavity through an intestinal perforation during the intrauterine or perinatal period. The perforation is known to be related to intrauterine vascular compromise. Recently, the authors experienced 4 cases of ileal atresia complicated by meconium peritonitis. The male to female sex ratio was 1 : 3, and age at operation was 1 day(2 cases), 3 days(2 cases). Three cases had generalized peritonitis, and one the cystic type of meconium peritonitis. The types of ileal atresia were IIIa(2 cases), IIIb(1 case), and II(1 case). The proximal blind ileal end was perforated in 3 cases, and distal end perforation was in 1 case of cystic type. Postoperative recovery was excellent in all cases.

Among all serious diseases globally, diabetes (type 1 and type 2) still poses a major challenge to the world population. Several target proteins have been identified, and the etiology causing diabetes has been reasonably well studied. But, there is still a gap in deciding on the choice of a drug, especially when the target is mutated. Mutations in the KCNJ11 gene, encoding the kir6.2 channel, are reported to be associated with congenital hyperinsulinism, having a major impact in causing type 1 diabetes, and due to the lack of its 3D structure, an attempt has been made to predict the structure of kir6.2, applying fold recognition methods. The current work is intended to investigate the affinity of four phytochemicals namely, curcumin (Curcuma longa), genistein (Genista tinctoria), piperine (Piper nigrum), and pterostilbene (Vitis vinifera) in a normal as well as in a mutant kir6.2 model by adopting a molecular docking methodology. The phytochemicals were docked in both wild and mutated kir6.2 models in two rounds: blind docking followed by ATP-binding pocket-specific docking. From the binding pockets, the common interacting amino acid residues participating strongly within the binding pocket were identified and compared. From the study, we conclude that these phytochemicals have strong affinity in both the normal and mutant kir6.2 model. This work would be helpful for further study of the phytochemicals above for the treatment of type 1 diabetes by targeting the kir6.2 channel.

This study aimed to evaluate the effect of dietary fiber supplementation with snack type on functional constipation. We conducted a double blind case-control study with 3 groups; placebo, low dose group (LD: insoluble fiber 7 g/d + soluble fiber 1.2 g/d) and high dose group (HD: insoluble fiber 14 g/d + soluble fiber 2.4 g/d) , which were randomly assigned out of subjects with functional constipation, defined by modified Rome II criteria. We measured anthropometric parameters and evaluated the bowel movement frequency, stool type, straining, sense of complete evacuation, abdominal discomfort/pain, abdominal inflation, relief and colon transit time before, during the supplementation. Both LD and HD groups had significant improvement in straining, sense of complete evacuation and satisfactory relief compared with placebo group (p < 0.05). When subdivide by baseline colon transit time (less than 24 hrs/ 24 hrs or more and less than 72 hrs / 72 hrs or more), only HD group had significantly improvement; colon transit time recovered near by 24 hrs in subjects of 'less than 24 hrs' (from $7.57{\pm}1.40$ hrs to $25.2{\pm}3.91$ hrs, p < 0.01) and reduced in those of '24hr or more and less than 72 hr' (from $47.0{\pm}3.36$ hrs to $31.3{\pm}4.31$ hrs, p < 0.01) and '72 hr or more' (from $106.7{\pm}10.7$ hrs to $85.0{\pm}13.1$ hrs, P < 0.05) subjects. Particularly, positive effect of fiber supplementation on straining and sense of complete evacuation in test groups seemed to be greater in subjects of '24 hrs or less' and '24 hrs or more and less' than 72 hrs' than those of '72 hrs or more'. In conclusion, subjects with functional constipation, particularly those having colon transit time less than 72 hrs can significantly improve, at least in part, symptom related to constipation by fiber supplementation of snack type without serious side effects.

Background: Most acromioclavicular joint (ACJ) injuries are caused by direct trauma to the shoulders, and various methods and techniques are used to treat them; however, none of the options can be considered the gold standard. This study examines the horizontal stability of the ACJ after a complete dislocation was repaired using one of two Ethibond suture techniques, the loop technique and the two holes in the clavicle technique. Methods: In this single-blind, randomized clinical trial, 104 patients diagnosed with complete ACJ dislocation type V were treated using Ethibond sutures with either the loop technique or the two holes in the clavicle technique. Horizontal changes in the ACJ were radiographically assessed in the lateral axial view, and shoulder function was evaluated by the Constant (CS) and Taft (TS) scores at intervals of 3, 6, and 12 months after surgery. Results: The horizontal stability of the ACJ was better with the two-hole technique than the loop technique at all measurement times. CS and TS changes showed a significant upward trend over time with both techniques. The mean CS and TS at the final visit were 95.2 and 11.6 with the loop technique and 94.0 and 11.9 with the two-hole technique, respectively. The incidence of superficial infections caused by the subcutaneous pins was the same in the two groups. Conclusions: Due to the improved ACJ stability with the two-hole technique, it appears to be a more suitable option than the loop technique for AC joint reduction.

This paper deals with the problem of channel identification for Single Input Multiple Output (SIMO) slow fading channels using clustering algorithms. Due to the intrinsic memory of the discrete-time model of the channel, over short observation periods, the received data vectors of the SIMO model are spread in clusters because of the AWGN noise. Each cluster is practically centered around the ideal channel output labels without noise and the noisy received vectors are distributed according to a multivariate Gaussian distribution. Starting from the Markov SIMO channel model, simultaneous maximum ikelihood estimation of the input vector and the channel coefficients reduce to one of obtaining the values of this pair that minimizes the sum of the Euclidean norms between the received and the estimated output vectors. Viterbi algorithm can be used for this purpose provided the trellis diagram of the Markov model can be labeled with the noiseless channel outputs. The problem of identification of the ideal channel outputs, which is the focus of this paper, is then equivalent to designing a Vector Quantizer (VQ) from a training set corresponding to the observed noisy channel outputs. The Linde-Buzo-Gray (LBG)-type clustering algorithms [1] could be used to obtain the noiseless channel output labels from the noisy received vectors. One problem with the use of such algorithms for blind time-varying channel identification is the codebook initialization. This paper looks at two critical issues with regards to the use of VQ for channel identification. The first has to deal with the applicability of this technique in general; we present theoretical results for the conditions under which the technique may be applicable. The second aims at overcoming the codebook initialization problem by proposing a novel approach which attempts to make the first phase of the channel estimation faster than the classical codebook initialization methods. Sample simulation results are provided confirming the effectiveness of the proposed initialization technique.

In banquets of royal courts held in the late Joseon Dynasty, a procedure that follows the customs as well as physical components to follow that procedure were necessary. A noticeable trait of the red blinds(朱簾) is that they are seen in the naeyon(內宴) types of banquets, which is mostly centered on the queen dowager and relatives, and they function as a makeshift facility that divide the different banquet spaces according to the hierarchy of the royal family. Furthermore, the red blinds within the court played an important role in the procedure of the banquet along with the incense, as it was drawn upon the queen dowager's appearance to signal the beginning, and folded out again to signal the end. This indicates that they were of higher importance within the banquet space. The red blinds used in the playacting stage of the royal court not only segmented the space, but also upon being taken down, expanded and integrated the banquet hall, thereby maximizing the playacting stage. Once the banquet was finished, the red blinds within the court were once again folded out so as to restore dignity to the space. The red blind is a symbolic item that could open the private space of the court so as to enable communication with the public space, and also close it off to restore privacy. Also, the layout of the banquet space was divided by the red blinds into primary, secondary, and tertiary hierarchal space, according to the status of the royal family and the banquet attendants. In other words, the red blinds played an important role in its the symbolic meaning in the national precedent as well as distinguishing the hierarchy of space within the naeyon banquet in the royal court.
