This study evaluated the effects of the number of feeding days and feeding rate on the growth of growing-out flounder Paralichthys olivaceus. Three replicated groups of fish ($141{\pm}1.9g$) were hand-fed a commercial feed under different feeding regimes for 9 weeks. Fish in group 6F-1S were fed to satiation twice daily for 6 consecutive days and starved for 1 day. Fish in groups 4F-1S and 3F-1S were fed to satiation twice daily for 4 and 3 days, respectively, and starved for 1 day. Fish in group 6F-90% were fed a diet of 90% of 6F-1S twice daily for 6 consecutive days and starved for 1 day. The weight gain, feed efficiency and daily feed intake of the fish groups in 4F-1S and 3F-1S were not significantly different from those of group 6F-1S. The weight gain and feed efficiency of fish in group 6F-90% were not significantly different from those of group 6F-1S. The results of this study suggest that the growth of growing-out flounder fed to satiation twice daily for 4 or 3 days after starving 1 day was similar to that of fish fed to satiation for 6 days, and that the proper feeding rate for growth could be lowered to 90% of satiation without growth suppression.

The 6-port phase correlator consists of one in-phase power divider and three 3-dB 90-degree phase difference power dividers, and is mainly used in a demodulation circuit that determines the phase of an input signal. This paper proposes the wideband 6-port phase correlator that consists of an in-phase power divider using a wideband 2:1 impedance transformer with three 37.5-Ω coaxial cables, and a 3-dB 90-degree phase difference power divide using Wireline. The proposed wideband phase correlator fabricated at a center frequency of 1000MHz has the value of the input reflection coefficient(S₁₁ and S₂₂) -14dB or less in the frequency range of 640~1270MHz. Also, the signal transmission characteristic(S_i1), from the in-phase power divider input port to four output ports, has the amplitude of -6.5±0.6dB and the phase error of within ±3.4°, and the signal transmission characteristic(S_i2), from the 90 degree phase difference power divider input port to four output ports, has the amplitude of -6.1±0.6dB and the phase error of within ±6.2°.

Since late 1960s, we have had the discourse about the way of succession of korean traditional architectural heritage. Through 60s and 70s, the formal mimesis and transformation was pretty much dominated in domestic design currents. After 80s, we could see a kind of different ways of design to deal with traditions in architectural practices. These methodology can be summarized as spatiality, abstraction and diversity. These discourses acted as bases for aesthetic and formal stream which might be needed to present the formal possibilities for various commercial needs. Especially, the interior design field utilized those ideas in order to show korean identity for the commercial needs such as korean restaurant, korean bar, or korean costume shop. Interior designers positively adapted the ideas from architectural discourse and created their own vocabulary after 90s. Before 90s, interior designers did very representational mimesis to express korean identity designing commercial facilities. However from mid 90s they could establish new tendencies in expressing korean traditional moods. These tendencies are a focus on spatial relationship, abstraction and materiality, utilization of traditional objects and lighting method.
