The purpose of this article is to investigate the forms and styles of pond at private housing in terms of diachronically influencing characteristics in the Choson Dynasty. From various literatures and records, we have selected 73 cases of pond. We have analyzed the types of pond based on square type, squared type with islets, and modified types and found the following results: 1) Chronically, shapes of pond had been chanced from the three prototypes into their features of deducting side or edge, adding a triangular or trapezoid shape, and installing more islets, and replaced their figures with gradually progressive from side having a straight lined shape to a curved one. 2) As for characteristics of arranging ponds, we found three patterns of arrangement - the juxtaposition with a similar shape of pond, juxtaposition with a different shape of pond, and the juxtaposition with a pond having different topological level in the light of the relation with a stream and a pond. We can conclude the two changed patterns of ponds at private residence in Choson Dynasty that the one had been transformed shapes of pond with sides of pond, and the others had been transformed juxtaposition with either a stream or a natural stream. From this research we can find an important implications in understanding patterns and types of garden in the Choson Dynasty from exploratory approach and in the future the relationship between topographical characteristics of private residence and Confucian ideas, and shapes of pond is needed to be examined in explanatory manner.

This is a theoretical and empirical study on Kasaya, the Buddhist monk's robe, which is one of the traditional Korean costumes that has kept it original form, as well as it being the most symbolic ritual costume in Buddhism. The purpose of the study is to see the different types of Kasaya, and the transitions it has gone through since Mid Joseon Dynasty. The analysis was performed after categorizing Kasaya in the following manner: layers, the way to wear, symbolism in construction, sewing, etc. Having a variety of Ilwolguangcheop(日月光貼) is a feature of Korean Red Kasaya. In the beginning, Its shape was very similar to shape of Hyungbae(胸背), and this was a royal gift and had the same meaning as an official uniform for a Buddhist monk. So designs of the Cheop(貼) could have been transformed from those of Hyungbae with a Buddhist twist. The conclusion of the study is as follows: Double layered Kasaya shows its transition from double layer to single layer. The fastening ornaments have been simplified in all materials from Yeongja(纓子). The latch type and three-paired Yeongja type transformed into hook type and one-paired Yeongja type. Color is the most common feature above all, and it is mainly in red. The form of Korean Kasaya has a significant relation with development of Buddhism. The integration of the Zen sect would have influenced the integration of Kasaya, which shows diversity throughout the period.

$2 \times 2$ 요인계획법에서 주효과가 전혀 존재하지 않거나 단지 하나만이 존재하는 경우의 교호작용을 위한 일반적인 F 검정과 순위변환을 이용한 F 검정 (FR 검정)의 제1종 오류율과 검정력은 전반적으로 비슷한 수준이나 정규분포보다는 지수분포하에서의 FR 검정의 검정력이 상당히 높은 수준임을 알 수 있다. 반면에 주효과들이 모두 존재하는 경우의 FR 검정의 제1종 오류율은 F 검정에 비하여 효과의 크기가 증가할수록 감소하고 주효과의 구성방법에도 영향을 받으며, 검정력은 효과의 크기와 표본의 크기를 크게할수록 증가하되 FR 검정의 검정력은 F 검정에 비하여 낮은 수준이며 주효과의 구성방법 및 모집단의 분포형태에 따라 민감하게 변화함을 알 수 있다.

Using the genomic library constructed at the downstream of the niiA promoter, which induces the over-expression of an inserted DNA fragment, we have attempted to screen the genes affecting growth or development by over-expression. The wild-type strain was transformed using the AMA-niiA(p) library and cultured on 1.2 M sorbitol media, in which asexual sporulation is induced, but sexual development is repressed. Over 100,000 strains transformed to $pyrG^+$ were analyzed with regard to any changes in phenotype. Consequently, seven strains were isolated for further analyses. These strains were designated NOT [niiA(p) over-expression transformants] stains. Four of the strains were of the inducible type, and the remaining strains were of the multi-copy suppression type. Two of the inducible-type strains, NOT 1 and NOT40, harbored genes which had been inserted in reverse direction, suggesting that the mutant phenotypes had been derived from an excess amount of anti-sense mRNA. Domain analyses of the deduced polypeptides from the DNA fragments rescued from the transformants revealed that NOT1, NOT40 and NOT6 harbored a LisH motif, a forkhead domain, and a $Zn(II)_2Cys_6$ binuclear zinc cluster, respectively.

Generalizing twist moves of classical knots, we introduce $t(a_1,{\cdots},a_m)$-moves of virtual knots for an $m$-tuple ($a_1,{\cdots},a_m$) of nonzero integers. In [4], M. Goussarov, M. Polyak and O. Viro introduced finite type invariants of virtual knots and Gauss diagram formulae giving combinatorial presentations of finite type invariants. By using the Gauss diagram formulae for the finite type invariants of degree 2, we give a necessary condition for a virtual long knot K to be transformed to a virtual long knot K' by a finite sequence of $t(a_1,{\cdots},a_m)$-moves for an $m$-tuple ($a_1,{\cdots},a_m$) of nonzero integers with the same sign.

We investigate surface brightness profiles (SBPs) of dwarf galaxies in field, group, and cluster environments. Using images from the Korea Microlensing Telescope Network (KMTNet) Supernova Program (KSP) for the NGC 2784 group and SDSS for the Virgo cluster, SBP types are classified into profiles with single exponential (Type I), double exponential (Type II and Type III). Type II and Type III have smaller and larger outer sizes than inner sizes, respectively. SBP types of field dwarfs are compiled from a previous study. The distributions of SBP types are different in three environments. After comparing sizes of dwarfs in different environments, we suggest that since sizes of some dwarfs are changed due to the environmental effects, SBP types are able to be transformed. It makes that the distributions of SBP types in three environments are different.

The issues of preventive and condition-based maintenance, online monitoring, system fault detection, diagnosis and prognosis are of increasing importance. This study introduces a technique to detect and identify faults in induction motors. Stator currents were measured and stored by time domain. The time domain is not suitable for representing current signals, so wavelet transform is used to convert the signals onto frequency domain. The raw signals can not show the significant feature, therefore difference values between the signal of the health conditions and that of the fault conditions are applied. The difference values were transformed by wavelet transform and the features are extracted from the transformed signals. The dynamic time warping method was used to identify the fault type. This study describes the results of detecting fault using wavelet analysis.

The theological properties of aqueous suspensions of Black Hills bentonite were measured by using a Couette-type viscometer. Three kinds of flow units in aqueous bentonite suspension were postulated. Each has a different average relaxation time, one Newtonian. One of the non-Newtonian types is thixotropic, and the other is non-thixotropic. The thixotropic non-Newtonian unit is transformed to a Newtonian unit by shear stress. If the stress is relieved, the transformed unit returns to its original state. Two flow equations were derived by introducing chemical kinetics consideration for such a transition into the generalized theory of viscous flow. One equation describes the "upcurve," a diagram of rate of sheat versus shear stress, obtained by increasing the rate of shear, and the other relates to the "downcurve" obtained by decreasing the shear rate. The equations satisfactorilly describe the experimental thixotropic hysteresis of bentonite suspensions. The equations also were successfully applied to the flow curves of the suspensions containing various amounts of monovalent electrolyte (KCI).
