The purpose of this study was to evaluate the perception of students' and employees' perception with for their high school foodservicein Bustin area. For this purpose, questionnaires were distributed among the 324 students and 93 employees in 12 high schools in the Busan area. The students assessed the importance and performance of school foodservice as 4.00/5.00 and 2.97/5.00,, respectively, and the employees assessed the importance and performance of as 4.07/5.00 and 3.77/100, respectively. Tice importance mean scores of students wereshowed significantly (p<0.01) higher scores in internal environment factor and sanitation factor than those of employees, hut the performance mean scores of students wereshowed significantly (p<0.01) lower scores in all the factors than those of employees. The importance grid of students and employees showed that the items of the high with to the low with of consideration of preference in menu, appropriate the meal hours, rapidnessrapidity of service, and prompt dealing with complaints were high scores to the students, but low scoresto the employees. The performance grid of students and employees showed that the items of the low with students to the high with employeesfreslrness of food ingredients, offering the consistency of consistently good service, rapidnessrapidity of service, prompt dealing with complaints, communication between students and employees, and food cleanliness were low scores to the students, but high scores to the employees of dish. 'Therefore, it would seem to be desirable that the foodservice manager may be plans the strategies with the involvement of students in the process from planning the menu to proposinge of ideas for improvement.

A gneral method for the preparation of oxotungsten(Ⅳ) complexes of the type[WOLC1₂](Where LH₂= the Schiff base derived from salicylaldehyde and its derivatives, and S-methyldithiocarbazate) usingWOC1₄as a precursor, is described. The characterizationis performed by means of the usual physicochemical techniquences. In the complex the coordination around tungsten atom is approximately octahedral with two chloride ligands in the trans position, and the remaining two equatorial sites and two axial positions occupied by ONS donor atom set of L and the terminal oxygen. Consequently the imino nitrogen of the L ligand is trans to the terminal oxygen.

저자들은 최근 약 5㎝ 길이의 근위부 맬관을 가진 불완전 중복요도를 발견하여 이의 완전적출술을 시행하여 병리 검사상 편평 상피세포로 구성된 요도를 확인하였기에 문헌적 고찰과 함께 보고하는 바이다. Duplication of the urethra within a single penile shaft is a rare anomaly. These can be divided into those that are in the sagittal plane, which is most common, and those that occur side by side. In some cases, the accessory channel is complete, having a separate bladder opening and no communication with the more normal ventral urethra. In other case, the accessory urethra is incomplete, either ending blindly or communicating with the urethra distal to the bladder neck. We report on a 20-year-old male with incomplete double urethra.

$[M(NO)_2Cl_2]_n(M = Mo, W)$을 출발물질로 사용하여 3단계 합성과정을 거쳐 $[Cl(dppp)(NO)_2M({\mu}-pyz)M'(NO)_2(dppp)Cl][ClO_4]_2$와 $[Cl(phen)(NO)_2M({\mu}-pyz)M'(NO)_2(dppp)Cl][ClO_4]_2$(M,M'= Mo or W; phen = 1,10-phenanthroline; dppp = 1,3-bis(diphenylphosphino)propane; pyz = 1,4-pyrazine) 형의 새로운 대칭 및 비대칭 이핵 착물을 합성하였다. 최종 생성물은 실리카겔 칼럼($2{\times}20$ cm)을 통해 아세톤으로 용리시켜 분리하였다. 합성한 착물은 원소분석과 적외선, 핵사기 공명 및 전자 흡수스펙트럼 등을 이용해서 그 특성을 조사하였다. 적외선 스펙트럼은 모든 착물이 팔면체 구조로서 두 개의 NO기가 cis 위치로 배위되어 있음을 나타냈으며, $^1H$ 및 $^{13}C$ 핵자기 공명 스펙트럼은 이들 착물이 pyz가 다리결합하고 있는 이핵 착물임을 나타내었다. Several new symmetric and asymmetric homo and hetero dinuclear complexes of the type $[Cl(dppp)(NO)_2M({\mu}-pyz)M'(NO)_2(dppp)Cl][ClO_4]_2$ and $[Cl(phen)(NO)_2M({\mu}-pyz)M'(NO)_2(dppp)Cl][ClO_4]_2$(M,M'= Mo or W; phen = 1,10-phenanthroline; dppp = 1,3-bis(diphenylphosphino)propane; pyz = 1,4-pyrazine) were synthesized in three-steps starting from $[M(NO)_2Cl_2]_n(M = Mo, W)$. The final products were purified by eluting it through silica gel column ($2{\times}20$ cm) with acetone as the eluent. Characterization of these complexes and some related complexes was accomplished through UV-vis., $^1H$-NMR, $^{13}C$-NMR and IR spectroscopies as well as elemental analysis. The infrared spectra indicate that the NO groups occupy cis-positions of the octahedral. The $^1H$ and $^{13}C-NMR$ data for the new compounds revealed a dimeric structures with bridged pyz.

$[{Mo(NO)_2Cl_2}_n]$ 및 $[{W(NO)_2Cl_2}_n]$의 다핵착물과 킬레이트 리간드인 1,10-phenanthroline을 반응시켜 중성화합물인 $[Mo(NO)_2Cl_2(phen)]$ 과 $[W(NO)_2Cl_2(phen)]$을 각각 합성하였다. 아세톤 용매에서 이 cis-디니트로실 화합물과 과염소산 은(I)을 1:1로 반응시켜 $[Mo(NO)_2(phen)(S)Cl][ClO_4]$ 및 $[W(NO)_2(phen)(S)Cl] [ClO_4]$ (S = acetone)의 양이온 화합물을 얻었다. 이 1가 양이온 화합물과 피라진을 2:1의 양론으로 각각 반응시켜 $[Cl(phen)(NO)_2M(pyz)M'(NO)_2(phen)Cl][C1O_4]_2$(M = Mo, M' = W) 및 $[Cl(phen)(NO)_2M(pyz)M'(NO)2(phen)Cl][C1O4]2$(M = Mo, M' = W)형의 호모 및 헤테로 이핵착물을 합성하였다. 합성한 착물의 특성은 원소분석과, $^1H-,\;^{13}C-$핵자기 공명 및 자외선, 전자흡수스펙트럼을 이용해서 조사하였으며 이들 분광학적 결과로부터 디니트로실 이핵착물의 기하학적 구조가 피라진 다리 리간드를 중심으로 한 $C_{2v}$ 대칭구조임을 확인할 수 있었다. The neutral monomeric compounds $[Mo(NO)_2Cl_2(phen)]$ and $[W(NO)_2Cl_2(phen)]$ (phen= 1,10-phenanthroline) have been prepared by reactions of polymeric compounds $[{Mo(NO)_2Cl_2}n],\;[{W(NO)_2Cl_2}n]$ with chelate ligands. Additions of one equivalent of silver(I) perchlorate to these cis-dinitrosyl compounds in acetone solution produce $[Mo(NO)_2(phen)(S)Cl][ClO_4]\;and\;[W(NO)_2(phen)(S)Cl][ClO_4]$ (S = acetone). The homo- and hetero-dinuclear complexes, $[Cl(phen)(NO)_2M(pyz)M'(NO)_2(phen)Cl][ClO_4]_2$ (M = Mo, W) and $[Cl(phen)(NO)_2M(pyz)M'(NO)_2(phen)Cl][C1O_4]_2$ (M = Mo, M' = W) have been prepared by these monocationic complexes with pyrazine ligand respectively. These complexes characterized by elemental analysis, $1^H-\;and\;^{13}C-NMR$, infrared, and UV-visible spectroscopy are reported. The spectral data indicate that homo- and hetero-dinuclear complexes were symmetrical structures of $C_{2v}$.
