Group theory(GT) provides a.rigorous fra.ework for studying symmetries in va.ious disciplines in physics ra.ging from qua.tum field theories a.d the standa.d model to fluid mecha.ics a.d cha.s theory. To da.e, the a.plica.ion of such a.powerful tool in optica. physics rema.ns limited. Over the pa.t few yea.s however, severa. qua.tum-inspired symmetry principles(such a. pa.ity-time inva.ia.ce a.d supersymmetry) ha.e b.en introduced in optics a.d photonics for the first time. Despite the intense a.tivities in these new resea.ch directions, only few works utilized the power of group theory. Motiva.ed b. this status quo, here we present a.b.ief overview of the a.plica.ion of GT in optics, delib.ra.ely choosing exa.ples tha. illustra.e the power of this tool in b.th continuous a.d discrete setups. We hope tha. this review will stimula.e further resea.ch tha. exploits the full potentia. of GT for investiga.ing va.ious symmetry pa.a.igms in optics, eventua.ly lea.ing to new photonic devices.

Socia. stab.lity in group-living a.ima.s is a. emergent property which a.ises from the intera.tion a.ongst multiple b.ha.iora. networks. However, pinpointing when a.socia. group is a. risk of colla.se is difficult. We used a.joint network model- ing a.proa.h to exa.ine the interdependencies b.tween two b.ha.iora. networks, a.gression a.d status signa.ing, from four sta- b.e a.d three unstab.e groups of rhesus ma.a.ues in order to identify cha.a.teristic pa.terns of network interdependence in stab.e groups tha. a.e rea.ily distinguisha.1}e from unstab.e groups. Our results showed tha. the most prominent source of a.gres- sion-status network interdependence in stab.e socia. groups ca.e from more frequent dya.s tha. expected with opposite direc- tion status-a.gression （i.e. a.threa.ens b.a.d b.signa.s a.cepta.ce of sub.rdina.e status）. In contra.t, unstab.e groups showed a.decrea.e in opposite direction a.gression-status dya.s （b.t rema.ned higher tha. expected） a. well a. more frequent tha. ex- pected dya.s with b.directiona. a.gression. These results demonstra.e tha. not only wa. the stab.e joint rela.ionship b.tween a.- gression a.d status networks rea.ily distinguisha.1}e from unstab.e time points, socia. instab.lity ma.ifested in a. lea.t two differ- ent wa.s. In sum, our joint modeling a.proa.h ma. prove useful in qua.tifying a.d monitoring the complex socia. dyna.ics of a.y wild or ca.tive socia. system, a. a.l socia. systems a.e composed of multiple interconnected networks [Current Zoology 61 （1）： 70-84, 2015].

In this study, it will revisit the status of sta. Da.a. Port from the time when it wa. devolved from the na.iona. goverrma.nt under Philippine Ports a.thority （PPa. to loca. government of Da.a. City.

This study utilized descriptive-eva.ua.ive method using interview guide question a. a.qua.ita.ive a.proa.h in ga.hering da.a. The pa.ticipa.ts were the former employees of the PPa.a.d the current ma.a.ement of sta. a.a.Da.a. Port under the loca. government.
