  • Two ennomine species, Amblychia angeronaria Guen$\acute{e}$e and Peratostega deletaria (Moore), are reported for the first time from Korea. Amblychia angeronaria was collected from Isl. Gageo-do, in the south west of Korea. The species is distinguished by the large wingspan, the ochreous forewing with a row of large white dots on the postmedian and a grayish apical dot, and the grayish or dark ochreous hindwing with undulating postmedial line and dark grayish subterminal line. Peratostega deleraia was collected from Isl. Jeju-do, and can be distinguished by the dark brown forewing with a blackish dentate postmedian and a light brown apical dot, and the dark brown hindwing with the light brown subtermen and angulate termen. Diagnosis and description of the species are given along with figures of the male and female genitalia.

  • In Korea, 104 species of Notodontidae have been recorded. The genus Odontosia H$\ddot{u}$bner is characterized by the elongate and serrate margin of its forewing and the prominent harpe of valva and many spinular cornuti on the vesica of the male genitalia and the robust ductus bursae and large, ovate and sclerotized corpus bursae of the female genitalia. Only one species of Odontosia, O. patricia Stichel, 1918, has been reported from Korea. In this paper, Odontosia sieversii ($M\acute{e}n\acute{e}tri\grave{e}s$, 1856) is newly added to the Korean fauna based on three male specimens collected at Mt. Bangtaesan, Gangwon-do, Korea. Diagnosis for the species and photographs of adult and genitalia of the genus Odontosia are provided.

  • A nolid species, Roeselia triangulalis (Leech) is reported for the first time from Korea. Two males were collected from Jeju Island, South Korea. Roeselia triangulalis can be distinguished by the bipectinate male antennae, broad frons, long labial palpi, costally dark brownish spot and the rounded dark brownish postmedial line of forewing. In the male genitalia, the long saccus, the slender valve with distally expanded and spine-like harpe and long spinular cornutus of vesica are distinguishing characters. In the female genitalia, the simple sterigma, the long ductus bursae and the large ovate corpus bursae with a lip-shaped signum are distinguishing characters. Diagnosis and description of the species are given with the figures of the male genitalia.

  • Shape controlled synthesis of inorganic nanocrystals is one of the important issues in materials chemistry due to their novel shape dependent properties. Although various shapes of nanocrystals have been developed, a systematic account on the shape control of these nanocrystals still remains an important subject in materials chemistry. In this article, we will overview the recent developments in the geometrical shape evolution of semiconductor and metal oxide nanocrystals obtained by nonhydrolytic synthetic methods. Many structurally unprecedented motifs have appeared as zero-dimesional (D) polyhedrons, one-D rods and wires, two-D plates and prisms, and other advanced shapes such as branched rods, stars, and inorganic dendrites. Important parameters which determine the geometrical shapes of nanocrystals are also illustrated. In addition, as a possible application of such nanocrystals for biomedical sciences, we further describe their utilizations for cancer diagnosis through nanocrystal-assisted magnetic resonance imaging (MRI).

  • Feeding is an interaction between a child and caregiver, and feeding difficulty is an umbrella term encompassing all feeding problems, regardless of etiology, severity, or consequences, while feeding disorder refers to an inability or refusal to eat sufficient quantities or variety of food to maintain adequate nutritional status, leading to substantial consequences, including malnutrition, impaired growth, and possible neurocognitive dysfunction. There are 6 representative feeding disorder subtypes in young children: infantile anorexia, sensory food aversion, reciprocity, posttraumatic type, state regulation, and feeding disorders associated with concurrent medical conditions. Most feeding difficulties are nonorganic and without any underlying medical condition, but organic causes should also be excluded from the beginning, through thorough history taking and physical examination, based on red-flag symptoms and signs. Age-appropriate feeding principles may support effective treatment of feeding difficulties in practice, and systematic approaches for feeding difficulties in young children, based on each subtype, may be beneficial.

  • The genus Microplitis (Braconidae: Microgastrinae) is reported for the first time from Korea. The Microplitis has often quite small hypopygium, very short ovipositor and rugose propodeum with large aleola. The genus contains 190 described species, among them 19 speceis were recorded in Korea. Microplitis varicolor was established by Viereck in 1917. The species is found as new to Korea in this study. Microplitis varicolor is endoparasitoid, especially attacking species of Noctuidae (Insecta: Lepidoptera) including pests of leguminous crop. In this study, diagnosis, photographs and host lists are included.

  • The purpose of this study is to develop the systematic process on the discrimination of Sasang constitution with the pulse diagnosis apparatus. The pulse waves were acquired at the right and the left Guan point with 1420 people who were apparently healthy. In order to minimize the effect of aging on the shape of pulse wave, the age groups of 30s, 40s, and 50s were used. Taeum group was the best to classify, Soyang group was the worst. With the same group size, the sensitivity of Soyang group was increased. Input variables were selected with the consideration of the floating-sink ratio, tests of equality of group means, multiple comparison, multicollinearity, and structure matrix. To increase the sensitivity of Soyang, the variables which could tell the difference between Soyang and Soeum were selected.

  • The genera Dero and Allonais belong to the family Naididae. Most species in the genus Dero have unique morphological characters including a branchial fossa and/or gills at the posterior end of the body. The genus Allonais has no eyes unlike its close relative the genus Nais. Of these genera, one species of Dero, D. obtusa, was recently reported in Korea. However, the genus Allonais has not been recorded in Korea. Here, we report Dero dorsalis Ferroni$\grave{e}$re, 1899 and Allonais pectinata (Stephenson, 1910) with a diagnosis and illustrations.

  • From a result of surveys on the biodiversity monitoring for moths in Korea, six species of micro-moths that were never known from Korea are reported here for the first time from this country. They are: Udea pseudocrocealis(South, 1901) of the family Crambidae, which has been known as endemic to Japan; Epinotia albiguttata (Oku, 1974) of the family Tortricidae, which was known belonging to Hikagehamakia Oku, 1974; and four species of the family Gelechiidae: Protoparachronistis concolor Omelko, 1986 and P. discedens Omelko, 1986, which were described from Primorisk, Russian Far East; Thiotricha pancratiastis Meyrick, 1921, which is known from Isl. Jejudo, and Thiotricha sp. which is being described in a separate paper. Here we provide images of adults and genitalia for the unrecorded species with a brief diagnosis.

  • The genus Blacus Nees is cosmopolitan genus of the subfamily Blacinae. The members of genus Blacus endoparasites of colepterous larvae: Staphylinidae, Nitidulidae, Cryptophagidae, Scolytidae, Anobiidae, Curculionidae and Melyridae. Previously, 13 Korean species of the genus have been investigated by several researchers. In this study, eight species of the genus Blacus are reported for the first time from Korea: Blacus apaches Achterberg, B. chabarovi Belokobylskij, B. compressus Belokobylskij, B. fischeri Haeselbarth, B. interstitialis Ruthe, B. mamillanus Ruthe, B. robustus Haeselbarth, and B. ussuriensis Belokobylskij. Diagnosis and host records are given for each species.
