  • Colonial ascidian, Eusynstyela monotestis (Tokioka, 1953), is newly reported from Korean waters. The specimens of E. monotestis examined in this study were collected at subtidal zone of Beomseom, Munseom, Seopseom and Chagwido in Jeju-do by SCUBA diving. The genus Eusynstyela Michaelsen, 1904 is also new to Korean waters and it is distinct from other genera by having branchial sac with folds, longitudinal stigmata, hermaphrodite gonads on both sides, 1-2 male follicles in each gonad and body wall with endocarps. Eusynstyela monotestis is distinct from other species by having gonad with only single male follicle. In this paper, detailed descriptions and photographs of Eusynstyela monotestis (Tokioka, 1953) are provided.

  • Many articles on operative treatment strategies for osteochondral lesions of the talus (OLT) have been published. On the other hand, there are only a few reports on the conservative treatment of OLT. Understanding the natural history of OLT is essential to establishing the correct treatment. Conservative treatment might lead to comparable clinical outcomes compared to the current options of the operative treatment in isolated OLT lesions. OLT lesions can be divided into two (or possibly three) types. Hence, the prognosis and outcome of certain operative treatments should be evaluated further. The prognosis of OLT combined with instability or malalignment appears poorer than that of isolated OLT lesions. Therefore, concomitant pathologies should be evaluated together when treating patients with OLT.

  • This study aims to evaluate the cultural street and to find ways to revitalize a culture street. To achieve this, the study relied on empirical study method and the descriptive method; additionally, present condition survey was performed with a user interview. As a result, the item of 'night visit' shows the highest mean and the item of 'convenience of walking' follows. It means that this street has such a good condition in the convenience and accessibility of physical environment that it gives pedestrians pleasure like night activity and satisfying their curiosity. 5 lowest items of inquiry, however, are all about regional history and origin. It means that this cultural street did not reflect the history and embody the original form of the street. Also, this study proposes 4 type of street; a street with contents, a street with sequence, a street for pedestrians, and a street with identity.

  • A colonial ascidian, Synoicum clavatum has previously been reported from Japan. Here, we provide detailed descriptions and illustrations of S. clavatum as the first record in Korea. Synoicum clavatum is characterized by club-shaped colonies with oval head and elongate stalk, circular cloacal systems, a branchial sac with 14-16 stigmata rows of 10-17 stigmata per row and a stomach with smooth surface. The specimens of S. clavatum were collected in the subtidal zone (15-25 m depth) at Beomseom and Mumseom in Jeju-do while SCUBA diving from 2000 to 2014.

  • We here report nine species of Tephritidae and five species of Platystomatidae from North Korea deposited in the Hungarian Natural History Museum (five new Korean records marked with asterisks): Acidiella pachypogon, Campiglossa $absinthii^*$, C. hirayamae, C. $loewiana^*$, Sphaeniscus atilius, Tephritis $brachyura^*$, Tephritis $sinensis^*$, Trupanea amoena, Xanthomyia $alpestris^*$, Rivellia alini, R. apicalis, R. asiatica, R. longialata, and R. nigroapicalis. Except for C. hirayamae, all other species are newly recorded in North Korea. As a result, a total of 22 tephritid and five platystomatid species are recognized for the North Korean tephritoid fauna. In South and North Korea together, a total of 120 nominal species of six tephritoid families are now officially recognized (1 Lonchaeidae, 1 Pallopteridae, 1 Ctenostylidae, 14 Platystomatidae, 14 Pyrgotidae, and 89 species of Tephritidae).

A Study on the Constructional Intention and Aesthetic Consciousness in the Architecture of Tongdosa Jajang-temple (통도사(通度寺) 자장암(慈藏庵)의 건축에 내재된 조영의도(造營意圖)와 미의식(美意識)에 관한 연구)

  • This paper aims at proposing constructional intention and aesthetic consciousness in the architecture of Jajang-temple, which was originally built by the great monk, Jajang in 7c. The results are as follows : 1) The layout and form of buildings in Jajang-temple were remarkably followed the situations and shapes of natural rocks related to Gumwa legend about the original establishment of the temple. 2) As natural rocks were penetrated into both the inner and outer space of buildings and so artificial skills were more or less restrained, it seems to be short of geometrical regularity, symmetry and formal integrity. 3) However it can be said that these architectural treatments were based on the aesthetic consciousness, so called In-Cha and Jol-Bak, which were conceived by intellectual elites in Chosun dynasty.

Geometric Style and Two-Dimensional Transformation : Alois Riegl's Theory of Visual Perception and Vienna Art Nouveau Architecture (기하양식과 2차원적 각색 : 알로이스 리글(Alois Riegl)의 시지각이론과 비엔나 아르누보 건축)

  • Alois Riegl's aesthetic theory of visual perception provided one of important conceptual backgrounds for Vienna Art Nouveau architecture. Riegls theory of visual perception consists of geometric style and two-dimensional transformation. Riegl's theory of geometric style is based on the modern aesthetic theory of abstraction, which says that the artistic perfection can be obtained not from a direct imitation of natural objects, but from an abstract transformation of them. Riegl's theory of two-dimensional transformation, on the other hand, aims at obtaining artistic perfection by disintegrating volumetric conditions of natural things into planes and combining the planes thus obtained into another new world of art. These two theories of Alois Rigl's provided an important aesthetical background for the design strategy of 'abstract ornamentaion of two-dimension' in Vienna Art Nouveau architecture. This paper is to review the basic concept of Alois Rigl's theory of geometric style and two-dimensional transformation.
